[Upgraded Version: ESD Protection Diodes] Produced by Hugen, tinysa with latest hardware V0.3.1, the displayed version info is "ESD protected" meaning the diodes are installed which will be more stable and sensitive with higher antistatic level and longer service life. NOTE: Due to the old inventory might mix with the new batch, and If you got the old version TinySA and want a new one, you could apply a replacement for it.

[Frequency Range] Spectrum analyzers like the tinysa use a resolution filter that is used to isolate the input power in a small frequency range. This resolution filter is swept across the desired frequency range. The fastest scanning speed occurs with an RBW or 300kHz or wider and is about 2 scans per second. But with increase of the frequency span and decrease of the RBW the scanning speed decreases quickly. A scan from 0MHz to 350MHz with an RBW of 10kHz takes about 2 minutes.

[2 in 1 Device] 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. The tinysa contains all the components of a conventional heterodyne swept spectrum analyzer.
