*IDN?
IDENTIFICATION QUERY queries the instrument identification.
The device response is for example: "Rohde&Schwarz,R&S SML01,00000001,1.04"
01 = variant identification
00000001= serial number
1.04 = firmware version number
*IST?
INDIVIDUAL STATUS QUERY returns the contents of the IST flag in decimal form (0 | 1). The
IST flag is the status bit which is sent during a parallel poll.
*OPC
OPERATION COMPLETE sets bit 0 in the event status register when all preceding commands
have been executed. This bit can be used to initiate a service request.
*OPC?
OPERATION COMPLETE QUERY returns 1, if all preceding commands have been executed. It
is necessary to consider a sufficiently long time-out for the IEEE/IEC-bus.
* OPT?
OPTION IDENTIFICATION QUERY queries the options included in the instrument and returns a
list of the options installed. The options are separated from each other by means of commas. For
every option, a fixed position is provided in the response.

*PRE 0 to 255
PARALLEL POLL REGISTER ENABLE sets the parallel poll enable register to the value
indicated. Query *PRE? returns the contents of the parallel poll enable register in decimal form.
*PSC 0 | 1
POWER ON STATUS CLEAR determines whether the contents of the ENABle registers is
maintained or reset in switching on.
*PSC = 0 causes the contents of the status registers to be maintained. Thus a service request
can be triggered in switching on in the case of a corresponding configuration of
status registers ESE and SRE.
*PSC 0 resets the registers.
Query *PSC? reads out the contents of the power-on-status-clear flag. The response can be 0 or 1.
