Scanning

Scan Count

You can specify the number of times the instrument will sweep through the scan list. When the specified number of sweeps have occurred, the scan stops.

•Select a scan count between 1 to 50,000 scan sweeps, or continuous.

•During an Interval Scan (see page 80), the scan count sets the number of times the instrument will sweep through the scan list and therefore determines the overall duration of the scan.

•During a Scan Once operation (see page 82), the scan count sets the number of front-panel key presses or scan trigger commands that will be accepted before terminating the scan.

•During an External Scan (see page 83), the scan count sets the number of external trigger pulses that will be accepted before terminating the scan.

•During an Alarm Scan (see page 84), the scan count sets the number of alarms that will be allowed before terminating the scan.

•You can store up to 50,000 readings in non-volatile memory during a scan. If you set a continuous scan and memory overflows (the MEM annunciator will turn on), a status register bit is set and new readings will overwrite the first readings stored (the most recent readings are always preserved).

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

•From the front panel, a Factory Reset (Sto/Rcl menu) sets the scan count to continuous. From the remote interface, a Factory Reset (*RST command) sets the scan count to 1 sweep.

•Front-Panel Operation:

00020 SCANS

The default is CONTINUOUS. To set the count to a value between 1 and 50,000 scans, turn the knob clockwise and enter a number.

•Remote Interface Operation:

TRIG:COUNT 20

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