19.3.1 Responses of the component cascade
The "Deembedding" > "Cascade" tab combines the S-parameters of all included com-
ponents and shows the response curves of the measurement setup for each S-param-
eter:
●
Magnitude response
●
Phase response
●
Group delay response
While the response curves on the component tabs show the S-parameter characteris-
tics of a single component, the cascade shows the combined characteristics for all
components including the mismatch between the components. The DUT is not consid-
ered.
Port selection
Selects the S-parameter. The response curves (magnitude, phase, and group delay
response) of the setup cascade for the selected parameter are shown. You can refresh
each graphic, and display it on full screen.
19.3.2 Responses of the measurement setup
On the "Deembedding" > "Response" tab, you see the resulting transfer function char-
acteristics of the deembedded measurement setup. These response curves include
also the characteristics of the DUT and its interaction with the input connector of the
oscilloscope.
You can see the following characteristics:
●
Magnitude response
●
Phase response
●
Group delay response
●
Step response
Using these response curves, you can assess the correction of the signal by deembed-
ding. In particular, you can compare realtime deembedding with software deembedding
and check whether the accuracy of the realtime deembedding is sufficient for the mea-
surement task.

The graphic opens in full view, where you can analyze the response function: zoom
in and out, use the cursor.
On the "Response" tab, you see also some parameters of the uncorrected measure-
ment setup including the DUT. All parameters are related to a frequency range from
DC to the configured effective bandwidth.
