Get/Set output or input data rate in Hz
Get / Set the modulator type
Get / Set FEC code type
Define the code type;
(note: the codes OM73 and NONE
are supported only on the DISA
compliant military modem AMT73)
Get / Set the FEC code rate;
The code rate 1/4, 1/3, 9/10 are also
supported in DVB-S2B mode.
Get / Set Reed Solomon code rate
Get / Set the scrambler ON or OFF
Get / Set the Nyquist filter roll-off
Get/Set modulator or demodulator spectral
inversion. If demodulator is set to AUTO, it
automatically senses incoming spectral
inversion and inverts if detected. Only inverts
the modulation eye pattern I and Q.
Get/Set interface sources
(Back panel Input / output ports or loopback)
Get/Set the differential encoder
and decoder to ON or OFF
Get/Set the 10 MHz Reference
ON or OFF; Applies the 10 MHz reference to
the BUC and/or LNB.
Set the compatible Turbo mode
on the modulator / demodulator.
