Envionic FA845 HF+LF spectrum datalogger

904,00 € tax excl.

New product

This new device has all the functions of the FA735, and also has a new feature, a spectrum analyzer.

The difference: 

The spectrum analyzer can be tuned to any frequency from 10 MHz up to 3.7 GHz. The sensitivity is better than the wideband sensitivity of the FA735.  The FA845 still also has the wideband RF mode that the FA735 has.

More details


More info

The spectrum analyzer is slower than wideband, however, because it has to scan the frequency range, and in one second it can, for instance, measure 100 different frequencies (while the wideband mode measures all frequencies at the same time).

The frequency range and bandwidth can be selected, and pre-set settings are available for the frequency bands of interest. You can also program your own settings. The results of the scans are logged on the memory card.

The FA845 looks the same as the FA735.

The delivery includes instrument case, LogPer antenna (for 700 to 6000 MHz), memory card and a card reader.
