  • ...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 Tiny spectrum analyzer and want a new one, you could apply a replacement for it..
  • [Frequency Range] Spectrum analyzers like the Tiny spectrum analyzer 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 Tiny spectrum analyzer contains all the components of a conventional heterodyne swept spectrum analyzer. Color display showing 290 scan points covering up to the full lo....
