Examples of the use of Special Event Qualifiers
You have set up a system to make a series of DCV measurements if the input
signal reaches 0.9 V and continue to take measurements until the level reduces
below the threshold. The input signal is a varying DC voltage. The Initiate layer is
set to Continuous ON, the ARM layer events to Immediate. The Trigger layer is
setup to start taking measurements when the input signal reaches the preset
level. The required level can be manually set within the Trigger Setup menu. The
remote commands (from the default) are:
TRIGger:SOURce INT
TRIGger:LEVel 0.9
TRIGger :SLOPe POSitive
You have no control of the signal level to set the level above 0.9 V so you cannot
do a quick check that everything is correctly configured. To test that the system
will take measurements as required, you can send a special event qualifier
remote command to take one measurement:
TRIGger:SIG
The default Delay will be executed before the reading acquisition triggers. To
override the Delay, you would send TRIGger:IMMediate. Note that
TRIGger:IMMediate is not the same as TRIGger:SOURce IMMediate.
