– Once you have initiated the scan, the instrument will continue scanning until
you stop it or until the trigger count is reached. See “Trigger Count” on
page 157 for more information.
– Mx+B scaling and alarm limits are applied to measurements during a scan and
all data is stored in volatile memory.
–The CONFigure and MEASure? commands automatically set the scan interval
to immediate (0 seconds) and the scan count to 1 sweep.
– The instrument sets the scan interval to immediate (0 seconds) 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) > INTERVAL > SCAN INTERVAL
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.
Note: To stop a scan, press and hold the Scan (Measure) key.
Remote Interface Operation:
The following program segment configures the
instrument for an interval scan.
Note: To stop a scan, send the ABORt command.
Manual Scanning
In this configuration, the instrument waits for either a front-panel key press or a
remote interface command before sweeping through the scan list.
– All readings from the scan are stored in volatile memory. Readings accumulate
in memory until the scan is terminated (until the trigger count is reached or
until you abort the scan).
