The actual memory address index (1 to 999) can be selected usin
g
the
[:SOURce]:LIST:INDex[:NSELect] command. The selected memory address can
be requested by means of the [:SOURce]:LIST:INDex[:NSELect]? query.
A sequence list of memory addresses can be defined usin
g
the
[:SOURce]:LIST:SEQuence:STARt and [:SOURce]:LIST:SEQuence:STOP
commands.
A sequence list of memory addresses can be reported usin
g
the
[:SOURce]:LIST:SEQuence:STARt? and [:SOURce]:LIST:SEQuence:STOP?
queries.
The len
g
th of a sequence list, i.e., the number of volta
g
e and current points, can
be requested by the [:SOURce]:LIST:VOLTa
g
e:POINts? and

The source of the next step in the sequence list (the step tri
gg
er) can be defined
and requested by the [:SOURce]:LIST:SOURce command, respectively the
[:SOURce]:LIST:SOURce? query. The followin
g
sources are possible:
• If source = TIMer, the internal timer of the power supply is used to count
the step interval time.
• If source = EXTernal or BUS, the active tri
gg
er source depends on whether
the START line of the tri
gg
er bus at the rear of the power supply is active
or not. If active, step pulses from the external STEP input will cause the
next step to be performed. If not active, the next step will be performed
after the
