Review: A must have for any RF hobbyist. - When you consider that to buy a spectrum analyser with the features of the TinySA ten years ago it would have been comparable to the price of a small family hatchback car. So for the price of a cheap night out the TinySA is even more remarkable. What the hardware and software developers have achieved in such a small package and for the price is remarkable. I placed my order, via desertcart Prime, prior to reading the reviews so I was fearful I’d end up receiving one of the myriad of inferior copies, thankfully that was not the case and the unit I received was the genuine article. In my working life I had access to the cutting edge of test equipment technology, now that I’m retired my needs are more pedestrian but the TinySA easily meets these needs with features to spare. As well as displaying signals I’ve been able to determine their modulation and accurate keying speeds using squaring techniques and AM/FM detection methods with this analyser. The hardware and software developers need to be congratulated for creating this exceptional tool.
Review: Good functionality for a great price - I bought the TinySA Spectrum Analyser to check performance of UHF radio mic system Receivers and Transmitters running at frequenices up to 865 MHz, and it works well, both in generating signals to test the receivers and measuring signals from the transmitters. The Windows software that can be downloaded is not the best, and is not especially intuitive to use : I found that setting up signal parameters is often just as easy using the touchscreen on the device itself. The one advantage of the USB link to a computer is the button to capture the screen display from the analyser, and then save it in a choice of common image formats : that's a great way to record results of measurements.

## Features

- 【Frequency Range 】Tiny Spectrum Analyzer with two inputs, high quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. Color display showing 290 scan points covering up to the full low or high frequency rangefrequency range. The tinySA contains all the components of a conventional heterodyne swept spectrum analyzer.
- 【Built-in Calibration Signal Generator】When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 0.1MHZ-350MHz, UHF square wave output between 240MHz-960MHz. Built-in calibration signal generator that is used for automatic self test and low input calibration.
- 【Tiny Spectrum analyzers & ESD Function】Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz.Color display showing 290 scan points covering up to the full low or high frequency range. Bulit-in rechargeable battery allowing a minimum of at least 2 hours portable use.The performance of the 2021 latest version 3.1 will be more stable and sensitive, with a new ESD protrcted function enable the product to have a higher antistatic level and a longer service life.
- 【PC Control】Connected to a PC via USB it becomes a PC controlled Spectrum Analyzer.The USB interface implements the Serial over USB (CDC) protocol and there is a large set of commands that can be invoked over the serial interface. These command can be used to perform measurements or update internal settings. The driver for Windows will install automatically after connecting to a Windows PC. The driver for Linux is built into the kernel.
- 【Package List】1x Tiny Spectrum Analyzer; 2 x 20cm RF Cable;1 x USB Cable;1 x SMA Female to Female Connector;1x Touchscreen Pen;1 x SMA Telescopic Antenna.It's very useful as an antenna analyzer for your ham station, easy to set without fancy calibration.The firmware of the tinySA can be updated by the user. New versions of the firmware needed please contact seller for download link.

## Questions & Answers

**Q: Are these genuine a TinySA or one of the many fakes as described on tinysa.org**
A: There _are_  lots of fakes around and I believe the Amazon could have fallen foul of them. I did get mine from Amazon, viz:

https://www.amazon.co.uk/gp/product/B08HVJ8ZSF/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

which is fine. However, I'm told that, to be safe, Mirfield Electronics would be wiser.

**Q: Exactly how can I use this to find out the frequency of something?**
A: if you highlight the markers and scan up and down the peak freq will be highlighted

**Q: Can this be used to connect a directional antenna (used for a sim card huawei router) to fine tune the antenna direction for maximum signal reception?**
A: Hi Paul,
If the router uses the 800 or 900mhz 4G bands then possibly yes, but if the router uses the 1.8Ghz band then no as the maximum frequently of the Mini SA is 930Mhz.
I hope this helps.
Kind regards,
D.

**Q: will this help me to work out if someone is trying to jam my wifi? thanks**
A: Very doubtful: 

I don't think that the SA gets up to wifi. frequencies (2.4 and 4 GHz).

Most conflicts between wifi users relate to a very crammed bandwidth so other households are likely, quite inadvertently, to conflict with one another's traffic.
