To build a scan list from the remote interface:
–The MEASure?, CONFigure, and ROUTe:SCAN commands contain a scan_list
parameter which defines the list of channels in the scan list. Note that each
time you send one of these commands, it redefines the scan list. To determine
which channels are currently in the scan list, you can send the ROUTe:SCAN?
query command.
– To initiate a scan, execute the MEASure?, READ?, or INITiate command. The
MEASure? and READ? commands send readings directly to the instrument’s
output buffer but readings are not stored in memory. The INITiate command
stores readings in memory. Use the FETCh? command to retrieve stored
readings from memory.
See the Keysight 34970A/34972A Programmer’s Reference Help for more
information on using these commands.
– When you reconfigure a channel and add it to the scan list using MEASure? or
CONFigure, it is important to note that the previous configuration on that
channel is lost. For example, assume that a channel is configured for DC
voltage measurements. When you reconfigure that channel for thermocouple
measurements, the previous range, resolution, and channel delay are set to
their Factory Reset (*RST command) state.
– Each time you initiate a new scan, the instrument clears all previously stored
readings.
– To stop a scan, execute the ABORt command.
