Trigger Count<br />
Sweep Count<br />
Features and Functions 3<br />
You can specify the number of triggers that will be accepted by the<br />
internal DMM before returning to the “idle” state. The trigger count applies<br />
to both scanning and stand- alone DMM measurements (with no scan list).<br />
Select a trigger count between 1 and 500,000 triggers, or continuous.<br />
You can store at least 500,000 readings in memory and all readings are<br />
automatically time stamped. If memory overflows, the new readings will<br />
overwrite the first (oldest) readings stored; the most recent readings are<br />
always preserved.<br />
You can specify a trigger count in conjunction with a sample count and<br />
a sweep count. The three parameters operate independent of one<br />
another, and the total number of readings returned will be the product<br />
of the three parameters.<br />
The CONFigure and MEASure? commands automatically set the scan<br />
trigger count to 1.<br />
The instrument sets the scan trigger count to 1 after a Factory Reset<br />
(*RST command). An Instrument Preset (SYSTem:PRESet command) or<br />
Card Reset (SYSTem:CPON command) does not change the setting.<br />
Front Panel Operation: Scan (Configure) > SCAN TRIGGER > COUNTED|INFINITE<br />
Remote Interface Operation: TRIGger:COUNt<br />
To configure a continuous scan, send TRIG:COUNT INFINITY.<br />
The sweep count sets the number of sweeps per trigger event during a<br />
scan (a sweep is one pass through the scan list). The front- panel sample<br />
annunciator (“ * ”) turns on during each measurement.<br />
