The DUT perspective (upper left part of the dialog) now displays the selected DUT.
2. Activate the "Reference Impedance" tab.
3. In the DUT perspective, toggle select (one of) the related DUT ports.
4. Use the controls in the Reference Impedance tab to specify the impedance set-
tings. The user interface is identical to the one described in "Reference Impedance
tab" on page 355.
Frequency Offset tab
The "Frequency Offset" tab allows you to activate Parallel measurements on multiple
DUTs and to define a "Minimum Offset" between the stimuli.
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").
