Sets Number of Scanning Cycles
ARM:COUN<number> sets 1 to 32767 scans
through the channel list per INIT command.
Default is one scanning cycle.
Selects the Trigger Source
TRIG:SOUR defines the trigger source to
advance the scan. Default is TRIG:SOUR IMM.
TRIG:SOUR?
queries the current trigger source.
Sources are:
BUS = *TRG via HP-IB interface
EXT = Event In connector
HOLD = Hold triggering
IMM = Automatic advance
Selects Continuous Scanning Cycles
Use INIT:CONT ON or INIT:CONT 1 to enable
continuous scanning cycles. Default made is
fixed number of scans, with number set by
ARM:COUN<number>.
Selects Scan Mode
SCAN:MODE sets the RF multiplexers for
NONE, VOLT, RES, or FRES. NONE, VOLT,
and RES have no effect on RF multiplexer
operation.
FRES sets "paired-channel"
scanning.
Selects the Scan List
SCAN<channel_list> defines channels to
be scanned using the trigger source set by
the
TRIG:SOUR command.
Enables Scanning
INIT starts scanning for any trigger source
and closes the first channel in the channel list
.
Advances the Scan
TRIG can be used to advance the scan for
TRIG:SOUR BUS or TRIG:SOUR HOLD. The
command is not functional when TRIG:SOUR IMM
or TRIG:SOUR EXT is set.
