*OPC
Operation complete
Sets bit 0 in the event status register when all preceding commands have been execu-
ted. This bit can be used to initiate a service request. The query writes a "1" into the
output buffer when all preceding commands have been executed, which is useful for
command synchronization.
*OPT?
Option identification query
Queries the options included in the instrument. For a list of all available options and
their description, refer to the data sheet.
Return values:
<Options> The query returns a list of options. The options are returned at
fixed positions in a comma-separated string. A zero is returned
for options that are not installed.
Usage: Query only

*PSC <Action>
Power on status clear
Determines whether the contents of the ENABle registers are preserved or reset when
the instrument is switched on. Thus a service request can be triggered when the instru-
ment is switched on, if the status registers ESE and SRE are suitably configured. The
query reads out the contents of the "power-on-status-clear" flag.
Parameters:
<Action> 0 | 1
0
The contents of the status registers are preserved.
