2 Only Stimulus Menus
This section describes the menus that are available when the stimulus is set to
2 only.

TDT 2 dest

Pressing the TDT 2 dest softkey produces a pull-down menu used to select the
channel used as the destination channel for TDT measurements. The choices
available for this pull-down menu depend on the other TDR or electrical plug-
in, if any, in the mainframe.
Any electrical channel is potentially a valid TDT destination channel. The TDT
destination may not be assigned to a channel already assigned as a TDT
destination.
If no other valid TDT destination channels are available then "none" is the only
choice. If a TDT destination other than none is selected then the preset TDR/
TDT control will turn on and preset the TDT destination channel.

Normalize response . . .

The Normalize response function is available for all the Stimulus types except
differential and common mode. The Normalize response function allows you to
change the risetime of the normalized step, to select TDR and TDT
normalization, to turn on or off the display of the normalized TDR or TDT trace,
to change the scaling of the normalized trace, and to establish the normalization
filter values and reference plane.
Risetime
The Risetime function allows you to change the normalized step's risetime from
a minimum of
or
which ever is greater, to a maximum of
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
