Psk Subsystem - Hantek HDG 2000 Series User Manual

With the External modulating source, deviation is controlled by the ± 5 V signal level on the
front-panel MOD connector. For example, if you have set the frequency deviation to 180 degrees,
then a +5 V signal level corresponds to a +180 degree phase deviation. Lower external signal
levels produce less deviation, and negative signal levels produce negative deviation.
SOURce<n>:MOD:PM:INTernal:FREQuency <frequency>|MINimum|MAXimum
SOURce<n>:MOD:PM:INTernal:FREQuency? [MINimum|MAXimum]
Sets the frequency of the modulating waveform. The waveform chosen as the modulating source
will operate at that frequency, within the frequency limits of that waveform.
Parameter
2 mHz to 500 kHz, default 100Hz
Set modulating frequency to 10 kHz: SOURce1:MOD:PM:INTernal:FREQuency 10000
This command should be used only with the internal modulation source
SOURce<n>:MOD:PM:INTernal:FUNCtion SINusoid|SQUare|RAMP
SOURce<n>:MOD:PM:INTernal:FUNCtion?
Selects shape of modulating waveform.
Parameter
SINusoid|SQUare|RAMP, default
SINusoid
Select a square wave as the modulating waveform: SOURce1:MOD:PM:INTernal:FUNCtion
SQUare
This command should be used only with the internal modulation source
SOURce<n>:MOD:PM:SOURce INTernal|EXTernal
SOURce<n>:MOD:PM:SOURce?
Select the source(INTrnal or EXTenal) of the modulating signal.
Parameter
INTernal|EXTernal, default INTernal
Select external modulation source for CH1: SOURce1:MOD:FM:SOURce EXTernal

5.2.21 PSK Subsystem

PSK phase shift keying.is a digital modulation scheme that conveys data by changing, or
modulating, the phase of a reference signal (the carrier wave).
Any digital modulation scheme uses a finite number of distinct signals to represent digital data.
PSK uses a finite number of phases, each assigned a unique pattern of binary digits.
