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:
Not Available
To initiate the measurement trigger
system:
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 Keysight 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.
Not Available
To query the WTG_meas bit (bit 3):
STAT:OPER:COND?(@1)
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
a triggered measurement is desired.
The trigger system is waiting for a trigger signal in the initiated state.
You can immediately trigger the measurement as follows:
Not Available
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.
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.
