The marker suffix must be in the range between 1 and 10, the number of ports depends
on the analyzer model. No restrictions apply to channel, trace, and diagram suffixes.
In remote control, one active trace can be selected for each channel; see
​
chapter 5.3.2,
"Active Traces in Remote Control" , on page 343. This concept simplifies the remote con-
trol command syntax, because it allows the active trace in a particular channel to be
referenced by means of the channel suffix. To keep the syntax transparent, <Ch> is used
for channel settings (it denotes the configured channel), whereas <Chn> is used for trace
settings (it denotes the active trace in the channel).
6.2 Common Commands
Common commands are described in the IEEE 488.2 (IEC 625-2) standard. These com-
mands have the same effect and are employed in the same way on different devices.
The headers of these commands consist of "*" followed by three letters. Many common
commands are related to the status reporting system; see
​
chapter 5.5, "Status Reporting
System" , on page 349.
Table 6-1: List of common commands
Command Parameters / Remarks Short Description
*CLS
CLear Status
– / no query 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 and
the tooltip error messages for remote control.
*ESE
Event Status Enable
0...255 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 Queries the instrument identification string of the R&S ZNC, including the man-
ufacturer, the instrument type, its serial number, and the software revision. The
response is of the form "Rohde&Schwarz,ZNC<Max. Freq>-
<Ports>Port,<Serial_no>,<FW_Version> (e.g. Rohde-Schwarz,ZNC8-2Port,
1311.6004.12,12345,1.10.12)".
The IDN information is editable; see
​
"Define *IDN? + *OPT?" on page 319.
*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 exe-
cuted. 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.
The OPT information is editable; see
​
"Define *IDN? + *OPT?" on page 319.
