SCPI Commands for the Counter
VX4101A MultiPaq Instrument User Manual
3–101
OUTPut:TRIGger:SOURce <channel>,<count>
This command allows a Counter input to be used as a trigger source. Either
channel 1 or 2 can be selected. Selecting channel 0 turns this feature off. The
divisor is the number by which the input signal is divided (e.g. a divisor of 10 on
a 10 MHz signal will result in a 1 MHz trigger output). You can set up the front
end with SENSe commands to provide attenuation, gain, offset, and filtering as
you would for any other measurement. Likewise, the trigger threshold and
hysteresis may also be selected.
SENSe subsystem commands can be used to configure the front-end to condition
the signal appropriately or if INP:SET:AUTO is ON or ONCE an auto-level
operation will occur.
The Counter will perform an implied abort for an output command that is
received during a measurement. The measurement in progress will be terminated
and the output command will be executed.
The Counter will not perform an implied abort for an output query that is
received during a measurement.
NOTE. When the Counter is in this mode, it cannot be used to perform frequency
and period measurements. Sending any command which would alter the current
configuration of the counter will result in an implied abort of this operation.
This operation can also be stopped by sending an ABORt or by resending this
command with the channel set to zero (0).
