BANDwidth
This command is used to define how the minimum frequency offset between different port groups is
determined for Simultaneous Measurement with Frequency Offset.
The minimum frequency offset specifies the minimum frequency difference between the measurements
performed in parallel in any two different port groups. The frequency offset which is actually used may be
larger than the minimum offset as the firmware chooses the smallest multiple of the frequency spacing
between the points in a segment or in a linear frequency sweep, respectively, which is larger than the
minimum offset.
Channel number.
If unspecified, this parameter is set to 1.
The minimum frequency offset to be used is directly specified by the command
SOURce<Ch>:GROup:SIMultaneous:FOFFset:MOFFSet:DVALue.
The minimum frequency offset to be used is calculated by the firmware as a product
of the (possibly segment specific) measurement bandwidth and the factor specified by
the command
SOURce<Ch>:GROup:SIMultaneous:FOFFset:MOFFset:BWFactor. In this
calculation of the minimum frequency offset neither static nor dynamic bandwidth
reduction of the measurement bandwidth is considered, the firmware uses the
measurement bandwidth as it has been specified via
SENSe<Ch>:BWIDth[:RESolution] (for the entire sweep) or via
[SENSe<Ch>:]SEGMent<Seg>:BWIDth[:RESolution] (segment specific).

SOURce<Ch>:GROup:SIMultaneous:FOFFset[:STATe] <Boolean>
This command is used to activate/deactivate the Simultaneous Measurement with Frequency Offset which
performs measurements within different port groups in parallel while applying different frequency offsets to
the measurements in different port groups.
Even when this flag is set to ON the Simultaneous Measurement with Frequency Offset may not be active
if not all preconditions for this mode are met. For each precondition there is a unique return value for the
query SOURce<Ch>:GROup:SIMultaneous:FOFFset:CONDition? which is returned when the
according precondition is not met. A complete list of all preconditions for the Simultaneous Measurement
with Frequency Offset can be found in the description of its return values. It is possible to first activate the
Simultaneous Measurement with Frequency Offset and afterwards issue other remote commands to set
up all necessary preconditions.
Channel number.
If unspecified, this parameter is set to 1.
ON | OFF – activates or deactivates Simultaneous Measurement with
