Common Commands
Common commands are described in the IEEE 488.2 (IEC 625-2) standard. These commands have the
same effect on different devices. The headers of these commands consist of "*" followed by three letters.
Many common commands are related to the status reporting system.
Command
Parameters
Short
Description
*CLS CLear Status sets the status byte (STB), the standard event register (ESR) and the
EVENt -part of the QUEStionable and the OPERation registers to zero. The command does
not alter the mask and transition parts of the registers. It clears the output buffer and the
tooltip for remote error messages.
Clear Status;
no query
*
ESE
Event Status Enable sets the event status enable register to the value indicated. The
query *ESE? returns the contents of the event status enable register in decimal form.
0...255
Event Status
Enable
*
ESR?
Event Status Read returns the contents of the event status register in decimal form
(0 to 255) and subsequently sets the register to zero.

IDN?
IDeNtification returns the instrument identification. The (default) response is of the
form "Rohde&Schwarz,ZVL-6,1303.6509K06/100007,1.10", where:
ZVL-6 is the analyzer type
1303.6509K06 is the order number of the analyzer
100007 is the serial number of the analyzer
1.10 is the firmware version number.
The ID string can be configured in the System Config dialog or in via SETUP – General
Setup – GPIB – More – *IDN? Format.

Query; query only
*
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.
Individual Status
Query; query only
*
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.
The query form writes a "1" into the output buffer as soon as all preceding commands have
been executed. This is used for command synchronization.
Operation
Complete
*
OPT?
OPTion identification query queries the options included in the instrument and
returns a list of the options installed. The response consists of arbitrary ASCII response data
according to IEEE 488.2. The options are returned at fixed positions in a comma-separated
string. A zero is returned for options that are not installed.

Pass Control Back indicates the controller address to which GPIB bus control is
returned after termination of the triggered action.

PRE
Parallel poll Register Enable sets parallel poll enable register to the value indicated.
The query *PRE? returns the contents of the parallel poll enable register in decimal form.

PSC
Power on Status Clear determines whether the contents of the ENABle registers is
maintained or reset when the analyzer is switched on.
*PSC = 0 causes the contents of the status registers to be maintained. Thus a service
request can be triggered on switching on in the case of a corresponding configuration of
status registers ESE and SRE.
*PSC 0 resets the registers.

RST
ReSeT sets the instrument to a defined default status. The command resets all setups,
restoring the factory default values defined for remote control operation. In contrast the
command SYSTem:PRESet resets the active setup only. The default settings are indicated
in the description of commands.
Reset;no query

SRE
Service Request Enable sets the service request enable register to the value
0...255
