Manual operation: See "Minimum Offset" on page 576
SOURce<Ch>:GROup<Grp>:SIMultaneous:FOFFset:MOFFset:MODE <arg0>
This command is used to define how the minimum frequency offset between different
port groups is determined for Parallel 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 fre-
quency offset which is actually used may be larger than the minimum offset as the firm-
ware chooses the smallest multiple of the frequency step size between the points in a
segment or in a linear frequency sweep, respectively, which is larger than the minimum
offset.
Suffix:

Channel number.
If unspecified, this parameter is set to 1.
<Grp>
Parameters:
<arg0> DIRect | BANDwidth
DIRect
The minimum frequency offset to be used is directly specified by
the command SOURce<Ch>:GROup<Grp>:SIMultaneous:
FOFFset:MOFFset:DVALue.
BANDwidth
The minimum frequency offset to be used is calculated by the
firmware as a product of the (possibly segment specific) mea-
surement bandwidth and the factor specified by the command
SOURce<Ch>:GROup<Grp>:SIMultaneous:FOFFset:
MOFFset:BWFactor.
In this calculation of the minimum frequency offset neither static
nor dynamic bandwidth reduction of the measurement band-
width is considered, the firmware uses the measurement band-
width as it has been specified via [SENSe<Ch>:]BWIDth[:
RESolution] (for the entire sweep) or via [SENSe<Ch>:
]SEGMent<Seg>:BWIDth[:RESolution] (segment specific).

Manual operation: See "Minimum Offset" on page 576
SOURce<Ch>:GROup<Grp>:SIMultaneous:FOFFset:STATe <arg0>
This command is used to activate/deactivate a frequency offset for parallel measure-
ments on an R&S ZNB/ZNBT with Internal second source.
