Portable Tinysa Spectrum Analyzer

The TinySA Spectrum Analyzer is a remarkable tool packed with features in a compact, portable design. Despite its small size, it delivers accurate and reliable results, making it perfect for hobbyists and professionals alike. The interface is intuitive, with a clear display that’s easy to navigate, even for beginners. I’ve used it to analyze signals across a wide range of frequencies, and it performs exceptionally well, providing detailed insights that are usually found in much more expensive equipment. The rechargeable battery and portability are huge pluses, allowing me to take it anywhere. If you’re looking for a powerful, budget-friendly spectrum analyzer, the TinySA is an excellent choice. Highly recommended!

Who would have thought that you could have Spectrum Analyzer AND Signal Generator capabilities for such a great price? I've used this unit at home and to measure spectrum at a repeater site. It works well standalone, BUT connecting it to a laptop gives you a lot more flexibility, ease of use, and ability to save or record measurements for future sharing. I've also used the Signal Generator function. You can even enter PL or CTCSS tones for FM modulation to test repeater receivers.

I use this almost everyday working with rf mic systems. After a couple of months working with it I really like it as a way to see the rf space in the environments I work in. It’s not my only tool in my work but it helps me to plan out what frequencies I can use and what bands I can operate on. In that regard, It’s been a good tool. It’s held up well but im quite protective of my gear so im not throwing it around. But it seems reliable and a nice addition to my bag.

I purchased this meter from a known supplier that is listed as having a genuine meter. I am very happy with the TinySA, and it is good value for the money. I have no issues with reading the meter, and it's easy to perform the self-tests and calibration. I did have an issue with the strap being damaged upon arrival, and I did reach out to the supplier using the "Contact Us" however they did not respond back to me. It's a small matter, but it makes me wonder if there will be any support. I'm happy with the meter, but I needed to take away a star over the strap being damaged in the box, and no response from the supplier.

Utilization is daunting at first, through the website instructions and YouTube, I am able to explore a lot now, and know what I am looking at, I am not a professional in any means, so this was completely new to me, I utilize it now through my work on radios, primarily testing the range sweep for finding out if the radios are in tune our have drifted out of tune. I am still working on learning all the features, but it is a great tool. The readability is good, small screen, but you can hook it up to a computer for a broad view, battery life, so far, no issues with what I am using it for.

Nice little unit. Many years of bug box prime test equipment use. This little guy does a LOT of what the 5-digit units can do. Very useful tool.

The screen is a bit small but usable. With the software and USB it's much easier to use on a PC where you can make the display as big as you want. I tested it with a function generator for a frequency standard and it is acceptably accurate. Both the sine wave and square wave look like what you would expect. This is an excellent addition to my test gear at an amazing price. Came from a vendor recommended by the manufacturer as not a clone as well. I have been finding it very useful and hard to beat for this much money.

I've used HP SAs and to tell the truth this one won't meet Aerospace standards. But considering that most ham and consumer applications don't need that degree of compliance, imo, this device exceeds expectations. It has most of the features I expect from an SA. I trotted it through almost all of it's settings except for measuring phase noise. The accuracy of the device depends on how you set up the display and RBW. At first when measuring the frequency of the output of my handheld at 146.49 MHz the marker was way off but by adjusting the RBW and sweep settings it was spot on. Oh, btw, you'll run into the same issues when using a high end SA. The only limitation I see with the device is the upper limit of 900 MHz. But that can be worked around with an external mixer and the appropriate LO. We did that at the last place I worked at with an older noise figure meter that wouldn't work into the x-band. Since I don't intend to work above 70cm it isn't a problem for me. The only thing I need is a directional coupler for 3rd order measurements. I was disappointed with the PC interface software but I think that may be because it wasn't written for Win10. The documentation for the device will not teach one how to use an SA. It is not an O'Scope and the settings are not intuitive. This is a sophisticated piece of test equipment that requires training to use. I would recommend going to the HP or Agilent web sites to learn how to use their equipment which will port over nicely to this piece of gear (or find an Elmer).
