Basic Setup Limitations

It is recommended that you use the DUT based experience instead. If you use the TDR Setup explained in this topic, you cannot:

  • Run TDR Calibration Wizard
  • View T-Parameters
  • View S-Parameters

The standard DUT-based experience has the following advantages:

  • Easyest to use and most intuitive.
  • Shows available S-parameters and time domain parameters.
  • Allows use of the TDR Calibration Wizard.
  • Allows assignment of custom names to ports.
  • Ability to apply fixture DeEmbedding.

This version of the TDR Setup dialog is not recommended, but is provided for those users who desire a more traditional TDR setup experience. Four most users, you'll want to use the TDR DUT Based Setup dialog.

Click Setup > TDR Basic Control to open this dialog. Or, click the Trigger button, located at the bottom of the screen. With the TDR Basic Control setup dialog:

  • You can configure both differential and common mode traces to provide mixed stimulus S-parameters.
  • Time-domain parameters are not available.

As shown in above screen capture, the TDR Setup dialog includes drawings that represent each TDR head. The following table describes the controls that you can click on to configure the TDR step.

Click To Configure
On a channel symbol to configure the Channel Step
For a TDR module, turns the TDR step on and off.
For a receiver module or channel, turns the channel on and off.

To configure the TDR reflection waveform, use the Channel Setup dialog for the TDR module. If the TDR Basic Setup dialog's TDR Stimulus Mode setting is set to Differential, the Channel dialog will include vertical tabs from which you can configure either a Differential or Common Mode waveform. This is shown in the following screen capture.
