This command is used to set the duty-cycle of the square wave or the symmetry of triangular wave. The value is
given in percent .
Arguments
Type:
Numeric
Units: None (percent implied)
Range: 20 to 80
Rounding: to integer
Command Type: Setting or Query
Setting
Syntax:
:SOURce: DCYCle <ws><duty cycle value>
:SOURce: DCYCle <ws>MINimum|MAXimum
Query
Syntax:
:SOURce: DCYCle?[<ws>MINimum|MAXimum]
Response: NR3
4.13.2 OUTPut Subsystem
The Output Subsystem controls characteristics of the source's output. Included in this subsystem are the State and
Summing commands. The command structure is as follows:
:OUTPut
[:STATe] <Boolean>
:SUMming <Boolean>
Note: For model 4078, nothing changes in the commands above to control channel 1. But for channel 2, change
:OUTP to :OUTP2. For example, to change channel 2 output to ON, send the command: OUTP2 ON or
OUTP2 1.
4.13.2.1 Output State
:OUTPut [:STATe] <state 0,1>
This command controls whether the output is ON or OFF.
Arguments
Type:
Boolean
Command Type: Setting or Query
Setting
Syntax:
:OUTPut[:STATe]<ws>ON|1|OFF|0
Examples: :OUTP:STAT ON
:OUTP OFF
Query
Syntax:
:OUTPut[:STATe]?
Response: 0|1
4.13.3 Trigger Subsystem
The Trigger Subsystem is used to control the waveform triggering. The command structure is as follows:
:TRIGger
:MODE CONTinuous|TRIGger|GATE|BURSt
:BURSt <numeric value>
