TinySA Spectrum Analyzer HandHeld,100kHz to 960MHz Portable 2.8 inch Touch Screen Frequency Analyzer MF/HF/VHF UHF Input,As a signal generator with 650mA Battery

Used for identifying radio signals.

Neat little SA. Not particularly accurate, but good enough to show spurs and harmonics from transmitters.

Just an amazing piece of kit.I use the analyser, but of more use to me is the signal generator aspect.I mainly use it in the 70cm and PMR446 bands, but also at 2m too.For the price it's superb, but just be aware the FM modulator has a fixed deviation of 5Khz, not a criticism just a comment.Would I buy again ? Absolutely. Outstanding value for money.

For the cost this is a super device for teaching and analysing basic problems. It includes a signal generator and the connectors required for experimentation. Whilst not designed to compete with high end systems, I would definitely recommend this new version of the unit for basic work. Does not suffer from some of the issues mentioned in other forums. Very pleased with the device.

This is an excellent little device. The instructions are easy to understand, the display is clear and easy to read despite its small size. Being able to display it on a PC and to control it from that PC is a bonus as is the ability to use the device as a signal generator. The range covered is impressive, battery life is good and I am sure that this device will more than justify the cost.

There was no pen stylus in the box?

So far I have only used the aerial to measure the spectral levels of a transmitter. The self check function confirmed the basic operation of the unit and the self calibration function appeared to be consistent. It is very easy to overload the input to the analyser and when this happens distortion occurs. I recommend that extra attenuation is used to counter the problem. If levels are kept within bounds then the unit works well.

A super handy device for radio spectrum working, at least in my area of amateur radio. It is most useful as it is portable and I can use it in the pen for antenna tuning etc.It is too early to give a complete review, it needs a few months of use to describe all its uses.
