5 Triggering and Gating
System Trigger
The counter operates in one of three states depending on the status of the sys-
tem trigger: idle, wait for trigger, and triggered.
Idle State
Counter configuration generally occurs while the instrument is in the idle
state (Figure 5-3). This includes configuration of the system trigger.
As shown, the counter is placed in the idle state by either of the following the
commands:
ABORt - aborts a measurement in progress.
*RST - resets the counter to its factory default values.
The counter also returns to the idle state after the total number of measure-
ments determined by the TRIGger:COUNt and SAMPle:COUNt settings are
complete (i.e. # of measurements = TRIGger:COUNt x SAMPle:COUNt).
