– Once you have initiated the scan, the instrument will continue scanning until
you stop it or until the trigger count is reached. See
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.

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).
