Agilent Technologies L4400 manual Channel Delay, L4421A 40- Channel Armature Multiplexer

Operating and Programming 3

•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.

The following command sets the sweep count:

Usage:

•L4421A 40- Channel Armature Multiplexer

You can control the pacing of a scan sweep by inserting a delay between the L4421A channels in the scan list (useful for high- impedance or

high- capacitance circuits). The delay occurs following relay closure and any inherent settling time, and before the generation of the “channel closed” signal that would externally trigger a separate DMM (see “Scanning with External Instruments”).
