GPIB Operation ML24xxA Native Commands
ML2437A/38A OM/PM PN: 10585-00001 Rev. P 8-81
TRGLVL (Set trigger level)
TRGMODE (Change trigger mode)
Syntax: TRGLVL <c>,<val>
c: 1, 2 or 1&2
val: -30 to +20 dBm
Remarks: If the Trigger source is set to INTA or INTB (internal A or B) the system
triggers on a rising or falling power level edge. Use this command to set
the level the channel must rise above or fall below before it triggers
when in READOUT or Power vs. Time mode.
Select channel 1, 2 or 1&2. Selecting 1&2 allows both channels to trigger
together on the same conditions without having to set up two sets of
trigger data.
Query: TRGLVL? <c>
Returned String: TRGLVL <c>,<val>
The TRG type commands return the trigger state of the selected channel
if the channel is ON. This depends on the settings of the “link triggers”
flag and the current mode of the sensor on the selected channel. If the
channel is OFF, the stored trigger state of the channel is returned.
Syntax: TRGMODE <mode>
mode: IND, COMB
Remarks: Changes the trigger operating mode between INDividual channel
trigger setups and COMBined trigger set ups. Individual set up is when
the trigger conditions for each channel are setup separately. The
combined setup allows both channels to trigger together on the same
conditions.
If a channel is OFF or sensors used in both channel configurations do
not include a sensor set to CUSTOM measurement mode, the
COMBined trigger mode is not allowed, and sending the GPIB command
TRGMODE COMB will produce an execution error.
Query: TRGMODE?
Returned String: TRGMODE <mode>
