Review on SEESII Portable TinySA Spectrum Analyzer V0.3.1 With SMA Male To UHF Female Cables, 100KHz To 960MHz Frequency Range, 2.8'' Touchscreen And Signal Generator For MF/HF/VHF UHF Input Analysis by Anthony Rael

The TinySA works just fine! And so far in testing, the accuracy of this device is not to bad. First thing, an ACTUAL instruction manual would have been really nice. There is no documentation at all on how to operate the TinySA. Luckily there are several YouTube vids out there to help you along. The menu IS a bit confusing. There is a lot of back and fourth in the menu to set the parameters you desire. Once again, nothing is clearly explained. The "LISTEN” feature seems to be disabled, this allows you to listen in on the frequency being monitored. I don’t even think there is an actual speaker in this unit. This is my MAJOR DISAPPOINTMENT! As this feature would have been very handy from time to time.When doing the SELF TEST of CALIBRATION, the high and low ports must be connected together with the supplied jumper cable!If you do not follow this procedure, the unit will fail the test and not calibrate correctly. For the price, it’s definitely a great unit and worth every penny. Just watch the videos on how to use and setup the TinySA, as I stated. It is a bit confusing to operate.
