Command
Parameters
Description
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.
*ESR?
Event Status Read; query only
Returns the contents of the event status register in decimal form (0 to 255) and subsequently sets the
register to zero.
*IDN?
IDeNtification query; query only
Returns the instrument identification. The response is of the form "Rohde&Schwarz,ZVA8-
4Port,12345,0.10.1.23", where ZVxx-nPort is the analyzer type 12345 is the serial number of the
analyzer 0.10.1.23 is the firmware version number. The ID string can be changed in the System Config
dialog.
*IST?
Individual STatus query; query only
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.
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.
*OPT?
OPTion identification query; query only
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.
*PCB
0...30
Pass Control Back; no query
Indicates the controller address to which GPIB bus control is returned after termination of the triggered
action.
*PRE
0...255
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
0 | 1
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; no query
Sets the instrument to a defined default status by closing all open setups and creating a single setup
"Set1" with factory-defined or user-defined default settings (see PRESet:USER[:STATe]).
*SRE
0...255
Service Request Enable
Sets the service request enable register to the value indicated. Bit 6 (MSS mask bit) remains 0. This
command determines under which conditions a service request is triggered. The query *SRE? returns
the contents of the service request enable register in decimal form. Bit 6 is always 0.
*STB?
STatus Byte query; query only
Reads the contents of the status byte in decimal form.
*TRG
TRiGger; no query
Triggers all actions waiting for a trigger event. In particular *TRG generates a manual trigger signal
(Manual Trigger). This common command complements the commands of the TRIGger subsystem.
*TST?
self TeST query; query only
Triggers selftests of the instrument and returns an error code in decimal form.
*WAI
WAIt to continue; no query
Prevents servicing of the subsequent commands until all preceding commands have been executed
and all signals have settled (see also command synchronization and *OPC).
