*OPT?
This query requests the dc source to identify any options that are installed. Options are identified by
number. A 0 indicates no options are installed.
Query Syntax
*OPT?
Returned Parameters
<AARD>
*PSC
This command controls the automatic clearing at power-on of the Service Request Enable and the
Standard Event Status Enable registers. The query returns the current state of *PSC.
*PSC ON | 1
causes these registers to be cleared at power-on. This prevents a PON event from
generating SRQ at power-on.
*PSC OFF | 0
causes the contents of the Standard Event Enable and Service Request Enable registers
to be saved in nonvolatile memory and recalled at power-on. This allows a PON event
to generate SRQ at power-on.
Command Syntax
*PSC <Bool>
Parameters
0 | 1 | OFF | ON
Example
*PSC 0 *PSC 1

uncompleted trigger actions)
K the calibration function is disabled by setting CAL:STATe to OFF
NOTE: The device state stored in location 0 is automatically recalled at power turn-on when the
OUTPut:PON:STATe is set to RCL0.
