Demodulated Bitstream Output
The Demodulated Bit Stream Output sends a raw, synchronized bit stream (FSK, some PSK only)
through an XML interface to an external application.
When Demodulated Bit Stream Output is selected, the parameters of the decoder software (e.g., de-
modulator, shift frequency, center frequency etc.) must be set to correct values at first. The synchronized
bit stream - after demodulation - will now be available and is sent through the XML interface to a user ap-
plication.
For FSK signals the polarity is changed from the menu Options | Signal Polarity, and then using the
buttons in the window shown. For more information see “Signal Polarity” on page 43.
For PSK signals the configuration of the symbol definition is in the menu Options | Symbol Definition.
For more information see “Signal Polarity”.
If you select an FSK or PSK demodulator in Bitstream Output or Autocorrelation mode, the signal polarity
definition is available.
