TDT 1 dest
The TDT 1 dest softkey only appears when the Stimulus is set to on or external.
Pressing the TDT 1 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 a valid TDT destination channel. If external stimulus
is selected, the TDT destination may not be set to the currently defined TDR
destination channel.
