Operating Manual 1145.1084.12 – 30 985
<Ch>
Channel number.
<group_no>
Port group number.
In "set" direction this suffix is ignored.
Range [def. unit]
As port groups must be non-empty and disjoint, the maximum number of port
groups for an n-port analyzer is n. [–]
<log_port1>, ...
Numbers of all logical ports in the port group. The port numbers must be
omitted if the command is used as a query.
Range [def. unit]
Overall, the specified ports must define a non-empty subset of the set of logical
port numbers; repetitions are not allowed.

Types
Device-specific, command or query
Example:
See SOURce<Ch>:GROup<group_no>
SOURce<Ch>:GROup:SIMultaneous:FOFFset:CONDition?
This command is used to query the operation mode of Simultaneous Measurement with Frequency Offset.
The following list contains all possible return values of this query.
Please note that this query will return an error if the channel specified by <Ch> does not contain any trace.
This is due to the fact that without traces no measurements are performed so that no information about
Simultaneous Measurement with Frequency Offset is available.
This query waits until all previous commands are fully executed because these commands may affect the
operation mode of Simultaneous Measurement with Frequency Offset.
 0, "switched off"
Simultaneous Measurement with Frequency Offset is switched off, meaning
SOURce<Ch>:GROup:SIMultaneous:FOFFset[:STATe]? would return 0.
 1, "active"
Simultaneous Measurement with Frequency Offset is active, meaning it has been activated via
SOURce<Ch>:GROup:SIMultaneous:FOFFset[:STATe] ON and all preconditions for this
mode to be operational are met.
 -1, "too few port groups"
There must be at least two port groups defined, otherwise no parallel measurement is possible.
 -2, "invalid port groups"
The ports in different port groups must be pairwise independent regarding their source generator.
This means that on analyzers with every two ports sharing a source synthesizer, these ports may
not be in different port groups because in that case the ports in these port groups are not able to
operate at different frequencies as it is required for Simultaneous Measurement with Frequency
Offset.
 -3, "permanent port without port group"
Simultaneous Measurement with Frequency Offset will not be activated if there are permanent
ports defined in the port configuration which do not belong to any port group.
 -4, "invalid sweep type"
Simultaneous Measurement with Frequency Offset requires either a linear frequency sweep or a
segmented sweep.
 -5, "frequency converter not supported"
Simultaneous Measurement with Frequency Offset is not able to operate together with a
