While the TDR step's risetime applied to the system under test is fixed, the
measured response has a set of mathematical operations applied to it. These
mathematical operations effectively change the displayed response to the
system just as if a different TDR step risetime had actually been applied. This
allows you to select a risetime for TDR/TDT measurements that is close to the
actual risetime used in your system. This risetime value applies to both TDR
and TDT normalized channels. For more information on normalization, see the
chapter titled Improving Time Domain Network Measurements.

Key Path
TDR/TDT
The TDR/TDT function is used to select between TDR and TDT for normalization.
Both TDR and TDT channels can be normalized. This control selects which
normalized trace is referred to for the following controls. Before TDT
normalization can be done, you must select a TDT destination ( TDT 1 dest ).

Key Path
TDR or TDT normalize
The TDR normalize function is available if the TDR mode is selected by using
the previous menu otherwise the TDT normalize function is available. In either
case, this function turns on or off the display of the normalized trace. The TDR
and TDT normalization functions can be on at the same time.

Normalize scaling . . .
The Normalize scaling function is used when vertical and horizontal scaling of
the normalized response is required that is independent from that of the source
channel. This function only appears when TDR or TDT normalize is set to on.
