The Trigger mode may also be enabled in the local mode by programming setup parameters without depressing the
ENT key. The setup values will then be programmed in the remote mode when the Device Trigger is received.
3.7.17
TO PROGRAM THE OUTPUT WAVEFORM (WVF) (Optional)
The header WVF with the optional A, B or C extension is used to identify the following argument as the Sine Wave
(SNW) or Square Wave (SQW) function of the Waveform.
The following example will program all outputs to the square wave function.
WVF
SQW
The following example will program only output B to the square wave function:
WVFB
SQW
3.7.18
TO OPEN (OPN) AND CLOSE (CLS) THE OUTPUT RELAY
The OPN and CLS headers open and close the output relays in the power source. There is no argument associated
with these headers. When the OPN or CLS headers is received the output voltage will be programmed to zero volts for
50 milliseconds before the output relays open or close.
3.7.19
TO PROGRAM DROP CYCLE (DRP)
The DRP header is used to identify the Drop Command. The argument is a numeric data field from 1 to 5. The
following string will drop the output voltage for phase B for five complete cycles and start at 0 degree of the wave form.
Note that all drop angles are relative to Phase A.
PHZ A 120 DRP B
3.7.20
TO PROGRAM THE DEFAULT FREQUENCY (FLM A)
The default frequency is the output frequency after power-up or after an IEEE-488 Device Clear.
The following example will program the default frequency to 400 Hz.
FLM
A
400
3.7.21
TO PROGRAM THE DEFAULT OUTPUT VOLTAGE (INI A)
The default voltage is the output voltage after power-up, IEEE-488 Device Clear or an Amplitude fault.
The following example will program the default voltage to 5 volts.
INI A 5
NOTE
If the default voltage is programmed to a value less than 5 volts, the settling time will
increase. In addition, there may be an amplitude fault when the voltage is
programmed from the default voltage to a value less than 50% of full scale.
