Agilent Technologies Switch/Measure manual Trigger Count

Features and Functions 2

Front Panel Operation: Scan (Configure) > INTERVAL > EXTERNAL

To initiate the scan and store all readings in memory, press the

Scan (Measure) key. Between scan sweeps, “WAITING FOR TRIG” will be displayed on the front panel. When a TTL pulse is received, the scan starts and readings are stored in memory.

Note: To stop a scan, press and hold the Scan (Measure) key.

Remote Interface Operation: The following program segment configures the instrument for an external scan.

TRIG:SOURCE EXT	Select external mode
TRIG:COUNT 2	Sweep the scan list 2 times
INIT	Initiate the scan

Note: To stop a scan, press and hold the Scan (Measure) key.

Trigger Count

You can specify the number of triggers that will be accepted by the internal DMM before returning to the “idle” state. The trigger count applies to both scanning and stand- alone DMM measurements (with no scan list).

•Select a trigger count between 1 and 500,000 triggers, or continuous.

•You can store at least 500,000 readings in memory and all readings are automatically time stamped. If memory overflows, the new readings will overwrite the first (oldest) readings stored; the most recent readings are always preserved.

•You can specify a trigger count in conjunction with a sample count and a sweep count. The three parameters operate independent of one another, and the total number of readings returned will be the product of the three parameters.

•The CONFigure and MEASure? commands automatically set the scan trigger count to 1.

•The instrument sets the scan trigger count to 1 after a Factory Reset (*RST command). An Instrument Preset (SYSTem:PRESet command) or Card Reset (SYSTem:CPON command) does not change the setting.

Front Panel Operation: Scan (Configure) > SCAN TRIGGER > COUNTEDINFINITE

Remote Interface Operation: TRIGger:COUNt

To configure a continuous scan, send TRIG:COUNT INFINITY.
