Operation
Auto Sequencing
Setting Sequence Repetitions
Set the number of times a sequence will repeat before stopping execution.
PROG:REP {ONCE <sequence_count>FORINF}
•ONCE will run the sequence once and return it to its STOP condition.
•<sequence_count> ranges from 1 to 9999. It will run the sequence the number of times specified before putting it into the STOP condition.
•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 {BUSMANEXTIMM}
•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 setpoint, current setpoint, 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 OVP level: PROG:STEP<step_number>:OVP <OVPlevel>
•Program step time (duration): PROG:STEP<step_number>:DWEL {<time>TRIG}
Deleting Steps
To delete any step from the sequence:
PROGram:STEP<step_number>:DELete
Subsequent steps are shift up.
Note The default value for a sequence’s repeat time and trigger source is repeat once and trigger from key. See “Setting Sequence Repetitions” on page 62 and “Using Auto Sequencing” on page 63 for an explanation of how to edit these values.
