Product-Specific Commands—Description
:SENSe:DDEMod:MODulation?
Description This query returns the digital communication
format used by the demodulator.
At *RST, this value is set to DP-QPSK or QPSK. It’s
device dependent.
Syntax :SENSe:DDEMod:MODulation?
Parameter(s) None
Response Syntax <Modulation>
Response(s) Modulation:
The response data syntax for <Modulation> is
defined as a <CHARACTER RESPONSE DATA>
element.
Returns the modulation that is set.
APSK, Amplitude and Phase-shift keying as the
modulation for the digital communication format
is selected.
BPSK, Binary phase-shift keying (BPSK) as the
modulation for the digital communication
formatis selected.
DP-CW, Differential Quadrature keying (CW) as
the modulation for the digital communication
formatis selected.
DP-APSK, Differential Quadrature Phase-shift
keying (DPSK) as the modulation for the digital
communication formatis selected.
