To get access to the "Frequency Offset" configuration, set "Parallel Measurement" to
"Enabled") and activate the "Frequency Offset" tab.
It is essential to perform the calibration with the same "Frequency Offset" settings as
for the actual measurement; otherwise the calibration is deactivated ("Cal Off"). If there
is a mismatch, the Calibration Manager dialog provides additional information.
Parallel Measurement with Frequency Offset
Enables/disables a frequency offset in parallel measurements.
For segmented sweeps, the parallel measurements are performed segment per seg-
ment. If the Minimum Offset is specified as a "Bandwidth Factor" and the segments use
different measurement bandwidths, then the resulting frequency offsets are also differ-
ent.
Remote command:
SOURce<Ch>:GROup<Grp>:SIMultaneous:FOFFset:STATe
Minimum Offset
The "Minimum Offset" can be specified either as an absolute value ("Direct Value") or
as a multiple of the measurement bandwidth ("Bandwidth Factor").
Remote command:
SOURce<Ch>:GROup<Grp>:SIMultaneous:FOFFset:MOFFset:MODE
SOURce<Ch>:GROup<Grp>:SIMultaneous:FOFFset:MOFFset:DVALue
SOURce<Ch>:GROup<Grp>:SIMultaneous:FOFFset:MOFFset:BWFactor
State indication warning
When attempting to activate the "Parallel Measurement with Frequency Offset" (i.e. on
closing the "Define Parallel Measurement" dialog with the "OK" button), the VNA Firm-
ware checks whether the requested settings are technically feasible. If not, the firm-
ware disables parallel measurement (i.e. the measurements are performed one after
the other) and generates a warning message indicating the current configuration prob-
lem.
