System Trigger
The counter operates in one of three states depending on the status of the system 
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 measurements 
determined by the TRIGger:COUNt and SAMPle:COUNt settings are complete 
(i.e. # of measurements = TRIGger:COUNt x SAMPle:COUNt).
