There is some discussion on using another tinySA as a tracking generator here: https://groups.io/g/tinysa/topic/73309964. The more expensive GQ electronics version also has magnetic and electric field data, which makes it far more interesting to me. It is a surprisingly good instrument for less than $100 US. Chinese disregard of IP laws and their blatant lowest cost production standards cause poor quality copies that tarnish these brands and I urge everyone to make sure you only buy the genuine articles, both to be sure you get what you pay for, but also to support the original designers of the real products. Again, this was about 43 dBm down from the fundamental, meaning it was probably in compliance. For those of us who prefer a real manual, Kurt Poulsen, a ham from Denmark, has written up a comprehensive how-to document that might be of help. It is part of the Tektronix "Measurement Concepts" series. If you don't have a 0 ohm part use a very low value, under say 100ohms.
Here is the current copy of the V2.0 Schematic. https://www.arduino.cc/en/main/OldSoftwareReleases You will need to add the ESP32 capability to the IDE. But its the few bad ones who give a bad reputation to all the rest. Details below.. Your oscilloscope has a very low input impedance, typically 50 Ohms. As it happens, there is a relatively simple way to do this with "simpleSA". It is standalone with lcd display, portable device with battery. What differentiates TinySA from Nano VNA is the TinySA includes switchable input attenuators. Most obviously, the RTL-SDR does not have an integral battery, display screen and tracking generator output. Please be kind and respectful to help make the comments section excellent. /tinySA-user-manual-march2021.pdf. Nice to see proof that the Baofengs arent as bad as crudgedly old HAMS want to believe. The newer FW also solves the crash you have seen. The input/output specification of the tinySA is split over the 4 modes Low input mode spec: Input frequency range from 100kHz to 350MHz (with some limitations down to 10kHz) Input impedance 50 ohm when input attenuation set to 10dB or more. Ask Hackaday: Whats Your Tactical Tool Threshold? Thats not the case. Id rather use an old b/w TV set or green monitor. A race to the bottom doesnt even come close to describing most Chinese products. The base specifications on this are remarkably close to the NanoVNA which makes me think that theyre roughly the same thing under the hood. All connections are made using standard 0.1" headers and mating sockets.You can just see the edge of the ESP32 board mounted on the "RF" board, behind the display. Below: The "RF module". Then fit a short piece of wire is fitted as shown. There is a web site tinySA.org that has some details of a potentially commercially available version of Erik's original design. Like all prototypes, a few things usually go wrong ! Here's how I fitted them, using smd parts. What's in the Box - The TinySA Spectrum Analyzer - SMA-M Antenna
If not shure about quality dont buy but stop Is it possible to combine the two softwares into one on a single device? A flux pen can be handy also. The TinySA also has a more open design (the RTL-SDR is mostly implemented in a proprietary chip from Realtek) and has various useful SA features (attenuators, etc.). Pushing the jog wheel left or right moves the onscreen . https://scottyspectrumanalyzer.us. Is there a printable manual, like in a PDF.
Still, as I mentioned, their quality is higher and higher. You can put a spectrum analyzer into zero span mode with the power detector in linear mode (not logarithmic mode) and then adjust the trigger, sweep time, vertical position, and video bandwidth until you get a stable and meaningful time domain display. IMSAI Guy did an updated video teardown also. Again, this was only a rough test, with a test setup leaving much to be desired. The way it is its the best 50 bucks Ive ever spent (and I own high end HP gear as well). A few products with direct supervision and onsite QA are built to higher standards. Between it and the NanoVNA (which can also work as a signal generator) youve basically got $100-120 to get the RF (up to L-band) equivalent of a DMM very, very handy stuff.
I do not own a TinySA so I can not say if it has the modes necessary to allow it to be used as a zero span time domain analyzer. (shown at right center of the picture below.). It is based heavily on Erik's (PD0EK) original draft version but now uses a different micro controller and heavily revised software. And this is true for China as well as it is for western countries. The case of the tinySA is injection molded ABS, and a nice upgrade in look and feel from the open board design of the NanoVNA. Group Settings All members can post to the group. One is on loan to the president of the local ham club, and hes already planning to buy his own. Mine isnt that bad, but the NanoVNA to me without magnifying glasses is next to unreadable, and this one wouldnt change much, although Ill probably order one anyway just to support the project.
Twice as fast for the 2nd harmonic, three times as fast for the third, and so on. Spectrum Analyzer for 0.1-800MHz or, with Ultra mode enabled, level calibrated up to 6GHz. Right tool for the right job and all that. Connected to a PC via USB it becomes a PC controlled Spectrum Analyzer I may be a bit biased, since I was a beta tester for the tinySA, but I have to say the tinySA is a bargain. First Impressions A caveat: I'm by no means an expert on spectrum analyzers. I "might" alter the PCB at some time to V2.1 to correct that, but right now it's not on my to do list. Use as a Panadaptor.

Id submit that if these designer built these units in the US, Germany or Japan and sold them for 2x the China price, they would have a lot more happy customers who would actually could rely on the products they bought. Here we take a look at the TinySA ULTRA, a spectrum analyser and signal generator.Purchase here:https://s.click.aliexpress.com/e/_DkqY0AROther TinySA Ultra v. local time. A spectrum analyzer combined with a tracking generator, makes a very useful instrument to also allow sweeping of filters and such things. (V2.0 is almost identical, the parts that need to be added on V1 are present on V2.0) I will add this specific info soon for V2.0 As of 24th Aug though, nobody but myself has V2.0 panels. tinySA is very tiny handheld Spectrum Analyzer (SA). The panel is V-cut and is simply snapped into two individual PCB's to form the complete tinySA project.
Its a whole lot better than the RTL-SDR for lower frequencies The RTL-SDL (with the front end bypass for low frequencies) has a fixed internal sample rate 28.8 MSPS at 8 bits/sample, then decimated to a lower rate (1-2 MSPS) for the host.

This is just a taste of the "simpleSA" build. [see also links below for later versions] (NOTE R15 has been removed from the original Schematic links above) Right now I have NOT released Gerber files for this V2.0 version nor the software. You pay for a $50. It is always best to talk to other people who have purchased the product for their reviews. Spectrum analyzer =/= VNA, They might both deal with frequency and even have similar technology. With all the pleasantries dispensed, I turned to the one task pretty much every ham will want to turn a spectrum analyzer on: finding out just how bad the signal from a cheap handy talkie is. Because, of course, if a device shows you something, it must be precisely correct, right? The sine wave generated on the low output looked clean across the specified bandwidth, and the frequency was spot on. aaaaaa wrote a comment on CH552 USB Knob. I should have looked harder prior to posting my previous comment. To the left side is the input low pass filter and at the bottom edge you can see the two SAW filters with impedance matching components. NEW March 3rd 2021 I'm unsure if Dave keeps this upto date though. 100.
To AVOID SHORTS TO THE GROUND AREA , place a small piece of insulating tape under the parts. aaaaaa wrote a comment on CH552 USB Knob. I keep many of my files in triplicate on Dropbox, Google Drive and OneDrive. The tell-tale indications for internally generated spurs is that they move faster or slower than the expected rates for harmonics, or even moving in the opposite direction, or moving at the wrong rate as the center frequency is changed, i.e., if you change the CF by 1 MHz, any signal that does not move 1 MHz is a spur. A small problem was found though, 2 track cuts have to be made on one PCB. I dont have a use case for a good radio. While there are similarities, the tinySA is NOT NanoVNA hardware. The tinySA FW is based on the NanoVNA FW created by edy555. NOTE: For TG, TWO RF boards are required. Heres the teardown video link: Reserved. One end soldered to the connector pins, the other end linked across the 3v3 supply rail. It's in the form of a 100 x 100mm sized panel from a Chinese PCB supplier at low cost. Kurt describes the operation of the signal generator and spectrum analyzer functions and explains how to update the FW. March 3, 2021 These pages reflect FW version 1.3507 or later. Description: Transfer fuction in laymans term is output vs input and is usually in S domain. A second option is a PDF version of the wiki, which allows for easier reading for some people, that can be found here. The RTL-SDR is a receiver; there are ways to turn it into a spectrum analyzer, albeit with limited dynamic range and slow frequency scanning. The biggest is that the tinySA appears to crash when you click the screen off of one of the menus.
For 50 bucks, this thing is sweet! . A waterfall display is being looked at also. They are pull-ups on the I2C bus. @Dan Maloney: If your Baofeng was barely in-spec with at the 2nd order product, you are very likely to be waaay out of spec at the 3rd order frequency. Probably something like the Siglent SVA1015X or Rigol RSA3015N would be a better choice if you need both a VNA and spectrum analyzer, although the price point is a lot higher. Some modules on eBay will not cover that range, so ensure you buy the 240 - 960MHz modules. This has allowed it to grow much beyond its initial limitations over time. The device comes with a 2.8-inch resistive touch color display which shows the full frequency range in 290 scan points and has a rechargeable battery included for up to two hours of portable use. . When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between .1MHZ-350MHz, UHF square wave output between 240MHz-960MHz. Software:- see https://groups.io/g/HBTE files area. why do people always want Ferrari performance from a Volkswagon beetle? See the Groups.io HBTE group. At fifty bucks it is hard to say, no. If anything, it would be nice to have a, disposable, piece of test gear for situations where a lab grade instrument with NIST traceable calibration is not required. But if you want to do EMC pre-compliance probing and stuff like that, Id take the tinySA over nanoVNA for that job. aaaaaa wrote a comment on GPS device with ESP32. What now needs to happen Herb is for Erik to take all the code and create a new separate TinySA-App branch as I don't want to go any further into changing my program into a spectrum analyser program. The mods are only if the TG function is to be used and you built TWO RF boards. This is a copy of the changes, but please refer to the post above also. A suitable IF tap buffer and some amplification will be required before feeding into the simpleSA in this mode. Like the NanoVNA before it, the tinySA has the capability of PC control.
The conclusion that IMSA Guy reaches about the spurious indications was incorrect. Stop being triggered, it is the market position theyre trying to occupy. The tinySA hardware has components that the NanoVNA doesnt have, and the NanoVNA has components that the tinySA doesnt have. Try these sites: Theres a wiki here: https://www.tinysa.org/wiki/, And the groups.io group here: https://groups.io/g/tinysa/topics. Learn how your comment data is processed. You could probably modify the firmware to get some functionality, but I would guess the frontend would not be sensitive enough to be useful. Color display showing 290 scan points . There is another application specific to the TinySA here, appropriately named tinySA: http://athome.kaashoek.com/tinySA/Windows/, As noted here: https://tinysa.org/wiki/pmwiki.php?n=Main.PCSW. Donations can be done via credit card or PayPal. Reserved. Refer to the Schematic and BOM, as some parts need to be fitted on the rear or top of the PCB using either smd or axial parts. A built-in calibration signal generator that is used for automatic self test and (low) input calibration. I say this because Ive made similar looking devices.
connector JP1, we can easily add a second RF board for the tracking function. For those that prefer to read a document instead of browsing a wiki, there are two options. Ive got a bunch of li-ion cells in view of me right now labelled things like 5200mAh 9900mAh etc. (Comment Policy). (the upper frequency limit AND Si4342 module issues. Bill of material, software and other build documents will soo be available on GITHUB and a link will be placed here for that ASAP. If 3900 is used, also fit a 56k on top for best accuracy of the Cal output (-30dBm). I "might" alter the PCB at some time to V2.1 to correct that, but right now it's not on my to do list. Remove the SMA connectors before fitting. Details are in the Groups.io HBTE group, search for post #846. enthusiast. With Spektrum or GRC, from what Ive done, you can get a slow sweep so to have a wider bandwidth at the cost of sampling rate with the RTL-SDRs. The V2.0 PCB panel has arrived (Aug 19th, 2020). No warranty is given or implied that others may get the same results or that all parts may still be available. Page last modified on March 07, 2023, at 08:00 AM, Spectrum Analyzer with two inputs, high quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz or. Their picture can be seen much better from the shelve in the shack. I also found the touchscreen a bit finicky, which was a common complaint with the NanoVNA. This Install cross tools and firmware updating tool. Groups.io, tinysa@groups.io Notification
Is it asking too much to bump the screen size to 7? The RTL-SDR is OK but not great for 1.0 MHz 30 MHz. Industries that need specific alloys often get a bait-and-switch when they buy Chinese steel. Those products are cheap and also crappier than more expensive products. Manual. A spectrum analyzer is a tool that allows users to visualize signals on the radio spectrum. The original versions of the NanoVNA, NanoVNA2 and the TinySA are of much better quality (but still not lab quality) than what we will see from resellers in a few months. This hardly makes a fully usable and portable instrument so I decided to make a PCB for the "simpleSA" project and it is shown below. Erik is pretty clear that the code is still rough, and Im far from a Python guru so I might be having library problems that would be easy to fix for someone with more experience. Now you can get a $49 spectrum analyzer to go with it. It's an experimantal mode and experments are continuing. Most likely some shielding between the two RF boards will be needed of course. But unfortunately the TinySA doesnt go high enough in frequency to let you see the 3rd order products of a 70cm UHF transmitter. The minimum level is ~0.7 * 3v3 = 2.31v so there is a margin but not a lot.
The video compares the device to an HP 8591E spectrum analyzer. does the tinysa have the ability to compete with a 10k dollar (or more) spectrum analyzer? This cannot be undone. Some Si4342 modules may not cover that range, so Erik made some changes to the Si4342 module used as the local oscillator, to extend the range. The picture below shows how the 2 PCB's are stacked with the TFT display. Using this docker image and without installing arm toolchain, you can build the firmware. hell i could never afford an hp or other lab quality spectrum analyzers, but i can surely afford a tinysa! Overall, for $50, its a pretty handy device. The tinySA is a spectrum analyzer. project aim to provide an useful instrument for the RF There is also a groups.io Group which covers this device too. It reduces the overall current draw a little and still the BL level is OK. The tracking generator function can actually use the 'signal generator' function of the existing software but move it to the 2nd RF board and alter so it now tracks the SA function also. i am old enough to remember that japanese manufactured stuff was crap! Here it is at 30MHz and the Cal output is a nominal -30dBm. and took us a long time to catch up again. Briefly, the tracking generator has an oscillator which tracks that of the SA as it sweeps the selected band.
Are you sure you wish to delete this message from the message archives of tinysa@groups.io? Theres not a lot to see at first most of the interesting RF stuff is safely tucked under shielding. Page created by vk3pe (see QRZ.COM for contact details) April 2020. if you think they cant built top quality production facilities, again you would be sadly mistaken. A spectrum analyzer combined with a tracking generator, makes a very useful .
TINYSA USER MANUAL, FOR PRINTER, I never noticed him talking about Chinese product quality. To call these copies precision instruments is quite laughable. A tag already exists with the provided branch name. The NanoVNA made network analyzers cheap enough for almost everyone. This site uses Akismet to reduce spam. Here's how I fitted them, using axial (ie leaded) 1/4W parts. The PC can also be used to adjust parameters. the RF section. if you think they as a people are inferior to western people in production capability, you would be sadly wrong. A spectrum analyzer is a tool that allows users to visualize signals on the radio spectrum. Anyone who has used a NanoVNA will feel at home in the tinySA interface. The left side has two SMA jacks, labeled HIGH and LOW. The original tinySA uses several eBay modules which can be just connected up with co-ax cables and wires and connected to the PC. With so many weeks or months between the time of your impulsive click on the Buy Now button on AliExpress or eBay and the slow boat from China actually getting the package to your door, its easy enough to forget what exactly each package contains. You buy an ICOM for $400. Thats for good reason the code behind tinySA is a fork off the NanoVNA codebase, and the main developer of NanoVNA, edy555, is a contributor to the tinySA project, which is owned by Erik Kaashoek. This drawing gives an idea how the "simpleSA" is built. Hi, is there a similar device, but with a proper BAS output ? However, they may be useful for very casual measurements, fooling people who have no idea how to validate the results they see on the display. Watch [IMSAI Guy]s video after the break for his opinion. Very nice to have a nice manual. The PCB uses mainly SMD components, but with care, most any experienced builder should be able to tackle this project using standard hand tools. There are two pads on the PCB for the "FREQ OUT" and labeled on the PCB rear. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. I also have a giant box of 2800mAh cells from Japan. or tinySA Ultra for any spectrum analyzer product, without written permission. Well worth the watch if you want to know about the device, see it compared to some heavy iron on the bench, see how and why it is used, and get a fel for the good, the bad, and the ugly.
I decided to try the "tracking generator" function software which is being worked on at this time. And with the price of goods so low, the tendency to click and forget is all the easier. (On the V2.0 PCB, these parts will be part of the PCB.) Spectrum Analyzer Features. It is passive measurement as doesnt inject anything. Color display showing max 290 scan points providing gapless covering up to the full low or high frequency range. By enabling the ultra mode you acknowledge that you understand and agree with the limitations of the ultra mode.
As a beta tester, I received two tinySAs, versions 0.2 and 0.3, and as soon as they were available for purchase, I bought one. It has a switchable 2.6 kHz and 640 kHz bandpass filter, a 2.8 inch color screen displaying 290 scan points, a built-in attenuator adjustable from 0 dB to -31dB, Built-in 500mAh battery, auto calibration function and RF signal generator . Commercial ones are available and range from high end instruments either new or second hand, to relatively low cost units like the Rigole and Siglent instruments. I would definitely throw over 150 to an instrument like that. Some were serious, within the dynamic range and frequency range. If you have a modern scope it may already do this function, or you might be able to do a software solution. The . Another point to their advantage is that all the related industries are close together. This project looks to be an attempt to close off and monetize a bunch of work carried out by others. I found two Si4432 ISM transceiver chips, presumably one each for the high and low range of the tinySA. There is a good chance that if you are operating on High power and the 2nd order product is barely in-spec, then when you switch to Low power Ill bet you will see the carrier power drop but the 2nd order product amplitude will not change much. The tinySA is a mini portable spectrum analyzer, for the MF/HF/VHF bands from 100 KHz to 350 MHz and the UHF band from 240 MHz to 960 MHz in degraded mode. The built in signal generator function is handy, too, and the output level is high enough that you can use it as the LO for common double balanced mixers. Id like to hear what others have to say in regards to this assertion, or why I might be incorrect. There are some limitations, of course, but the price is right. Download. Itll be nice to have another signal generator around the shop. to simply blather on about china building shit, is to sit back and find out they have passed you by. Typo: Replace lower noise floor ~100dB for the frequency range spec. with lower noise floor ~-100dB for the frequency range spec., Heres Erik Kaashoek Youtube with new tinySA videos: https://www.youtube.com/user/superduramen/videos. Buyer beware. This Schematic is based on original work by PD0EK for a simple and low cost Spectrum Analyzer, known as "tinySA".

So, from now on, the version here is called "simpleSA" for lack of a better name at this stage. TRACE sets everything related to a trace. Welcome to the tinySAtm wiki! FREQ sets everything related to the frequency range to scan. tinySA is a trademark owned by its respective owner. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. Its very lightweight but feels solid in the hand. Yesterday there was an auto attenuate firmware upgrade. Posts to this group do not require approval from the moderators. You can see the Menu structure below. When you were measuring the Baofeng spurs did you have the transmit power in High or Low power mode?
All you need for smd parts is a soldering iron with about a 0.5 to 1mm tip, tweezers,a magnifying lamp or similar and solder wick to remove excess solder. Selectable resolution filters between 3kHz and 600kHz. Reference only!!. Erik's (PD0EK) Github page gives more information. An appeal to manufacturers: I understand that 2-3 screens are among the cheapest around, but please dont forget about people with less than perfect eyesight. Virtually no wiring is required, just the DC input if it's not being run from a USB port. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. Googling "TinySA", you will find a lot of reviews of it's performance by hams. Some amounted to little more than a radio scanner with visual display. It also fills a gap for NanoVNA owners trying to use the vna as a spectrum analyzer or signal generator. A PDF may be downloaded from. (this may change at a later date.)
