Setting Sequence Repetitions
Set the number of times a sequence will repeat before stopping execution.
PROG:REP {ONCE |<sequence_count>|FOR|INF}
•
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 {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 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
