Specification

go2MONITOR Specification


General

Classifier/Recognition:

  • The minimum signal length for the wideband modulation classifier is 100 ms.
  • Using the decoder (Recognition & Decoding) , the software is able to detect and process signals with a signal length of at least 1 ms.

Decoders and Demodulators:

  • MIL and PMR decoders may need an End-User-Certificate (depends on the country of the user)
  • One decoder = one line (to shorten the list). For the full list, download the actual decoderlist
  • Slow multi tone modems are recommended to operate with fixed nominal frequency
  • Obsolete decoders, end of live: See more information

Receivers:

  • The list can be extended on customer requests.
  • It is possible to connect multiple wide band an narrow band receivers to the software.
