13.7 DDS:WAVE:MODE
13.8 DDS:MODE:TYPE
13.9 DDS:MODE:WAVE:TYPE
13.10 DDS:MODE:FREQ
Set or query the duty cycle of the signal source
The query returns the duty cycle value
:DDS: DUTY 50 /*Set the signal source signal duty cycle to 50%*/
:DDS:DUTY? /*The query returns 50*/
:DDS:WAVE:MODE <bool>
:DDS:WAVE:MODE?
Set or query the modulation status of the signal source
:<bool> ::= {{1 | ON} | {0 | OFF}
The query returns ON, OFF
:DDS:WAVE:MODE ON /*Turn on signal source modulation*/
:DDS:WAVE:MODE? /*The query returns ON*/
:DDS:MODE:TYPE <type>
:DDS:MODE:TYPE?
Set or query the modulation type of the signal source
:DDS:MODE:TYPE AM /*Set the signal source modulation type to AM*/
:DDS:MODE:TYPE? /*The query returns AM*/
:DDS:MODE:WAVE:TYPE <type>
:DDS:MODE:WAVE:TYPE?
Set or query the modulation wave type when the signal source is modulated
:<type> ::= { SINE| SQUAre| RAMP}
The query returns SINE, SQUAre, RAMP
:DDS:MODE:WAVE:TYPE SINE /*Set the signal source modulation wave type to
SINE*/
:DDS:MODE:WAVE:TYPE? /*The query returns SINE*/
:DDS:MODE:FREQ <freq>
:DDS:MODE:FREQ?
Set or query the frequency of the modulating wave when the signal source is
modulated
Query returns frequency in scientific notation
:DDS:MODE:FREQ 1000 /*Set the signal source modulation wave frequency 1khz*/
:DDS:MODE:FREQ? /*The query returns 1.00000e+03*/
