3 Features and Functions
• The sweep count is valid only while scanning. If no channels have been
assigned to the scan list, the specified sweep count is ignored (no error
is generated).
• You can specify a sweep count in conjunction with a trigger count and
a sample count. The three parameters operate independent of one
another, and the total number of readings returned will be the product
of the three parameters.
• 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.
• The
CONFigure and MEASure? commands automatically set the sweep
count to 1 sweep.
• The instrument sets the sweep 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.

Sample Count
The sample count sets the number of auto- triggered samples the internal
DMM will take per channel per trigger. The sample count applies to both
scanning and stand- alone DMM measurements (with no scan list). The
front- panel sample annunciator (“ * ”) turns on during each measurement.
