Product-Specific Commands—Description
:SENSe:DDEMod:MODulation
Description
This command sets the digital communication
format used by the demodulator.
At *RST, this value is set to DP-QPSK or QPSK. It’s
device dependent.
Syntax

Parameter(s)
Modulation:
The program data syntax for the first parameter is
defined as a <CHARACTER PROGRAM DATA>
element. The allowed <CHARACTER PROGRAM
DATA> elements for this parameter are:
"APSK|BPSK|CW|DP-APSK|DP-BPSK|DP-CW|D
P-FreeRun|"DP-Intensity
Sampling"|DP-OOK|DP-16QAM|DP-QPSK|FREE
RUN|"Intensity Sampling"|OOK|16QAM|QPSK|".
Selects the modulation for digital
communication format used by demodulator.
APSK, selects Amplitude and Phase-shift keying
as the modulation for the digital communication
format.
