*PSC <numeric>
This is the power on status clear (reset on power-up) command.
If the argument is nonzero, the service request enable mask register (SRE) and the Event Status
Enable mask registers (ESE) are cleared at power-up. If the argument is zero, the above
mentioned registers retain their contents when the device is switched on and off. This enables a
Service Request when the device is switched on.

*RST
Reset acts on the tester setting like the RESET key.
This command does not change the status of the GPIB-bus interface, the set-GPIB-bus address,
the mask register of the Service Request function, or the output buffer. A current service request
is reset only if it has not been produced by a message in the output buffer.
ALL

Also influences the OPC bit in the event status register.

The options string consists of a comma-separated list. There is a position in the list for every option. If the option is
present, the option designator is given. If the option is not present, the designator is replaced with a “0.” For example, the
response for an instrument with only GPIB installed is “0,0,B60,B61,0,0,0.”
4
Any numeric value is accepted, but the result is rounded to either 0 or 1. A 0 enables the power-on SRQ, while a 1
disables the power-on SRQ.
