Differential and Common Mode Stimulus
Menus
This section describes the menus that are available when the stimulus is set to
differential
or common mode.
TDR/TDT
This TDR/TDT function allows you to select either TDR measurements or TDT
measurements. The TDT measurement capability requires that an additional
TDR or electrical plug-in module be installed in the mainframe.

TDR response 1
The
TDR response 1
function is used to enable or disable the display of the
differential or common mode TDR response 1. The choices available are off,
differential, or common mode.

Response scaling . . .
The
Response 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 response 1 is set to differential
or common mode.
Key Path TDR/TDT Setup
TDR response 1 Response scaling . . .
Vertical There are two choices for vertical mode:
track source
and
manual
.
The track source mode sets the control of the vertical scaling for the
normalized trace to that of the source channel. When manual mode is
selected, the
Scale
and
Offset
menus appear allowing you to independently
change the vertical scale and offset of the normalized trace.
