5.16.2.3 TDR Stimulus Settings dialog
This dialog allows you to configure the frequency sweep whose results are then used
for the time domain transformation and subsequent TDR simulation.
Access: System – [Applic] > "TDR" > "TDR Setup" > "Stimulus..."
After the settings are made, the resulting sweep parameters are shown in the lower
part of the dialog, as can be seen in the screenshot below.
Opening the dialog automatically activates the

Figure 5-73: TDR Stimulus Settings dialog
The "TDR Stimulus Settings" dialog offers basic settings. Instead of specifying the
sweep parameters directly, they are derived from time domain properties of the DUT.
After the settings are made, the resulting sweep parameters are shown in the dialog.
Advanced settings can be accessed via "Advanced Settings..." (see
Advanced Settings dialog"
Max. DUT Measure Delay / Max. El. Length / Max. Mech. Length
Defines the "length" of the DUT, which can either be specified as delay, electrical
length, or mechanical length.
Given the DUT's
i.e. setting one of them determines the other two.
Note: The length of the DUT determines the appropriate start frequency and step size
of the frequency sweep. It is important that the user enters a value that is at least as
high as the actual one. A higher value is acceptable as long as the resulting start fre-
quency is not below the analyzer's minimum frequency, which would be rejected by the
analyzer firmware.
