Sets Number of Scanning Cycles
ARM:COUNt <number> sets 1 to 32767
scanning cycles per INIT command.
Default is 1 scanning cycle.
Sets the Trigger Source
TRIG:SOUR defines the trigger source to
advance the scan. Sources are:
BUS = *TRG via GPIB interface
EXT = Event In connector
HOLD = Hold Triggering
IMM = Automatic advance (default)
TTLT = TTL Trigger Bus Line (0-7)
ECLT = ECL Trigger Bus LIne (0-1)
Enables Command Module "Trig Out" Port
Enables the Command Module's "Trig Out"
port, TTL Trigger bus line (0-7), or ECL Trigger
Bus lines (0-1).
Sets Continuous Scanning Cycles
Use INIT ON or INIT 1 to enable continuous
cycles. Default is fixed number of scans as
determined by the ARM:COUN command.
Selects Scan Mode
Sets NONE|VOLT|RES. This command has
no effect on the Relay Driver Module.
Selects the Channel List for Scanning
SCAN <channel_list> defines channels to be
scanned using the trigger source set by the
TRIG:SOUR command.
Enables Scanning
Enables scanning for any trigger source and
closes the first channel in the channel list.
Advances Channel List
Advances channel list when trigger source is
TRIG:SOUR BUS or TRIG:SOUR HOLD.
