Initiate the Measurement Trigger System
Next, you must initiate or enable the measurement trigger system.
When the power system is turned on, the trigger system is in the idle
state. In this state, the trigger system is disabled, ignoring all triggers.
The INITiate commands enable the trigger system to receive triggers.
To initiate the trigger system, use:
Front Panel:
Not Available
It takes a few milliseconds for the instrument to be ready to receive a
trigger signal after receiving the INITiate:ACQuire command, and it
can take longer for Agilent Models N678xA SMU.
If a trigger occurs before the trigger system is ready for it, the trigger
will be ignored. You can test the WTG_meas bit in the operation
status register to know when the instrument is ready to receive a
trigger after being initiated.
Front Panel:
Not Available
If a bit value of 8 is returned in the query, the WTG_meas bit is true,
and the instrument is ready to receive the trigger signal. Refer to the
N6700 Programmer's Reference Help file for more information.
It will be necessary to initiate the measurement trigger system each time a
triggered measurement is desired.
Trigger the Measurement
The trigger system is waiting for a trigger signal in the initiated state.
You can immediately trigger the measurement as follows:
Front Panel:
Not Available
As previously discussed, a trigger can also be generated by another
output channel or an input pin on the digital port connector. If any of
these systems are configured as the trigger source, the instrument
will wait indefinitely for the trigger signal. If the trigger does not
occur, you must manually return the trigger system to the idle state.
Operating the Power System 4
SCPI Command:
To initiate the measurement trigger system:
INIT:ACQ (@1)
SCPI Command:
To query the WTG_meas bit (bit 3):
STAT:OPER:COND?(@1)
SCPI Command:
To generate a measurement trigger:
TRIG:ACQ (@1)
Alternatively, if the trigger source is BUS,
you can also program a *TRG or an IEEE-488
<get> command.
