Common commands are taken from 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 register to zero. The command does not
alter the mask and transition parts of the registers. It clears the output
buffer. |
|
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. |
|
Standard Event Status Query;
query only |
|
*IDN? IDeNtification query 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
Configdialog. |
|
Identification 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 query writes
message "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. |
|
Option Identification Query;
query only |
|
*PCB Pass Control Back indicates
the controller address to which GPIB bus control is returned after termination
of the triggered action. |
0...30 |
Pass Control Back;
no query |
|
*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. |
0...255 |
Parallel Poll Register Enable |
|
*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. |
0 | 1 |
Power On Status Clear |
|
*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 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. |
0...255 |
Service Request Enable |
|
*STB? STatus Byte query reads the
contents of the status byte in decimal form. |
|
Status Byte Query;
query only |
|
*TRG TRiGger 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. |
|
Trigger;
no query |
|
*TST? self TeST query triggers selftests
of the instrument and returns an error code in decimal form
(the output is zero in the current firmware version). |
|
Self Test Query;
query only |
|
*WAI WAIt to continue prevents servicing
of the subsequent commands until all preceding commands have been executed
and all signals have settled (see also command
synchronization
and *OPC). |
|
Wait to continue;
no query |
