SCPI Commands for Digital Interfaces
TM-XDOP-01XN 4–39
• FORever and INFinity cause the sequence to repeat forever. A query will
return 9.9E37, representing INFinity.
Selecting a Trigger Source
If any triggers are programmed into the sequence, select a trigger source:
PROG:TRIG:SOUR {BUS|MAN|EXT|IMM}
• BUS - trigger signal is IEEE 488.1 GET or *TRG
• MANual - trigger input is from the front panel TRIGGER key
• EXTernal - The external trigger line is selected as the source.
• IMMediate - The source is the SCPI command “INIT:IMM”
Editing Step Parameters
Commands are provided to edit only one of voltage, current, power, OVP level,
step duration, or end action.
Program step voltage:
PROG:STEP<step_number>:VOLT <voltage>
Program step current:
PROG:STEP<step_number>:CURR <current>
Program step power:
PROG:STEP<step_number>:POW <power>
Program step OVP level:
PROG:STEP<step_number>:OVP <OVPlevel>
Program step time (duration):
PROG:STEP<step_number>:DWEL {<time>|TRIG}
To delete a step:
PROGram:STEP<step_number>:DELete
An error will result if the last step with the end action is deleted, without a new
end action programmed to take its place.
Deleting Sequences
If you no longer need a sequence, select it with the PROG:NAME command and
then delete it with the following:
PROGram:DELete
You can also use the following to delete all sequences:
PROGram:DELete:ALL
