R&S ZNB/ZNBT
The analyzer provides numeric suffixes for channels, traces, ports, markers etc. If
unspecified, a numeric suffix is replaced by 1.
The number of ports depends on the analyzer model. No restrictions apply to number
of markers, channel, trace, and diagram suffixes.
In remote control, one active trace can be selected for each channel; see
ter 6.3.2, "Active traces in remote
remote control command syntax, because it allows the active trace in a particular chan-
nel to be referenced by means of the channel suffix.
To keep the syntax transparent,

7.2 Common commands
Common commands are described in the IEEE 488.2 (IEC 625-2) standard. These
commands have the same effect and are employed in the same way on different devi-
ces. The headers of these commands consist of "*" followed by three letters. Many
common commands are related to the status reporting system; see

Short Description
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.
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.
Returns the contents of the event status register in decimal form (0 to 255) and
sets the register to zero.
Queries the instrument identification string of the R&S ZNB/ZNBT, including the
manufacturer, the instrument type, its serial number, and the software revision.
The response is of the form Rohde-Schwarz,ZNB<Max.
Freq>-<Ports>Port,<Order and Serial No.>,<FW_Version>, e.g.
Rohde-Schwarz,ZNB8-4Port,1311601044100005,2.90.1.125.
The IDN information is editable; see
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.
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" to the output buffer when all preceding commands have been exe-
cuted. This logic is used for command synchronization.
