IQ Pulse Inspector | Digital Signal Decoder

The IQ Pulse Inspector block offers a fully automatic digital signal burst/pulse classification and demodulation/decoder:

IQ Pulse Inspector and Decoder Block


You can record IQ data and get this displayed within a waterfall view.

Within this view you can mark and select any signal of interest and get an automatic real-time classification and decoding. You can also run an automatic classification over the full recording which will give you a table of all found signals (which can go into the thousands).

You can then select any signal within the table for an automatic decoding.


Single signals/bursts can be saved as I/Q data e.g. for setting up an own database. In addition the marked/decoded signal will be display within an own view and will be send for further process to the SPECTRA or IQ output. The pulse detection is adjustable e.g. you can change Minimum Rise and Minimum Power.

The Pulse Rate and Pulse Center from the selected pulse will be shown in detail:

We have just added ASK, PSK and FSK Demodulation.

We just integrated an autodetect of QPSK and BPSK decoding into the IQ symbol decoder.
