The Cortex HDR provides two different operating modes for the Playback function:
 Replay of data using the Test Modulator (Test Modulator mode). In this case the data are sent
to the Test Modulator for modulation and re-transmission at the IF level (720 MHz or 1.2 GHz).
The data can be demodulated by the Demodulators just as in real time reception.

 Replay of data at the ECL outputs (Data + Clock mode). In this case the data are sent directly to
the ECL outputs of the selected demodulator(s) in the selected output format. The Test
Modulator is not used nor the demodulation function of the Demodulators.
