go2signals go2DECODE Technical data

The performance of the software products depends on the hardware used. Technical parameters can differ under real operational conditions.
The parameters specified are limit values that cannot be guaranteed in all combinations. Specifications subject to change

Recognition

  • 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 decoder list
  • Slow multi tone modems are recommended to operate with fixed nominal frequency

Receivers:

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