Note:

●

For a R&S ZNB with a single internal source or a R&S ZNBT frequency shifted par-

allel measurements are not available.

●

The port groups have to be set up exactly as in the VNA GUI, when "Enabled" is

selected in the "Define Parallel Measurement" dialog.

The measurement is then performed on port group 1 (ports 1 and 2) and port group

2 (ports 3 and 4) in parallel, applying a configurable frequency offset to port group

Even if the parallel measurement is properly configured and this flag is set to ON, the

frequency offset may not be active if not all preconditions are met. For each precondi-

tion there is a unique return value for the query SOURce<Ch>:GROup<Grp>:

SIMultaneous:FOFFset:CONDition which is returned when the according precon-

dition is not met. A complete list of all preconditions can be found in the description of

the command's return values. It is possible to first activate the frequency offset and

afterwards issue other remote commands to set up all necessary preconditions.

Suffix:

<Ch>

Channel number.

If unspecified, this parameter is set to 1.

<Grp>

Parameters:

<arg0> ON | OFF – activates or deactivates frequency shifted parallel

measurements
