*OPT?
This query requests the ac 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 as follows (see Chapter 4 under “Programming the Status
Registers” for register details):
1 or ON
Prevents the register contents from being saved, causing them to be cleared at power-on.
This prevents a PON event from clearing SRQ at power-on.
0 or OFF
Saves the contents of the Service Request Enable and the Standard Event Status enable
registers in non-volatile memory and recalls them at power-on. This allows a PON event to
generate SRQ at power-on.
The query returns the current state of *PSC.
Command Syntax

Parameters
0 | 1 | OFF | ON

WARNING: Recalling a previously stored state may place hazardous voltages at the ac source output.
This command restores the ac source to a state that was previously stored in memory with a *SAV
command to the specified location. All states are recalled with the following exceptions:
u CAL:STATe is set to OFF
u the trigger system is set to the Idle state by an implied ABORt command (this cancels any
uncompleted trigger actions)
NOTE: The device state stored in location 0 is automatically recalled at power turn-on when the
OUTPut:PON:STATE is set to RCL0.
