Category: Measuring, testing & control

Type: Quick start guide

Keysight E5071C ENA Option TDR, an advanced tool for high-speed digital designs, provides deep insights into the behavior of your devices and interconnects. With its ability to perform Time Domain Reflectometry (TDR) and Time Domain Transmissometry (TDT) measurements and analyze Eye Diagrams, this device empowers you to thoroughly evaluate signal integrity and characterize your designs accurately. This option offers a comprehensive range of features, including:

Comprehensive analysis of transmission and reflection parameters in both time and frequency domains
Support for single-ended, differential, and mixed-mode measurements

Comprehensive analysis of transmission and reflection parameters in both time and frequency domains
Support for single-ended, differential, and mixed-mode measurements

•To start the ENA Option TDR application, press “[Analysis] – TDR”.

After pressing the TDR softkey to turn the application ON, the

firmware will restart to enter the TDR mode.

Note:

•Firmware restart is requires since the ENA Option TDR uses

a different data process than the ENA

Exiting the Application

•Clicking on the [X] button closes the TDR application GUI, but

the TDR application (MODE) is not closed

•To close the TDR application (MODE), press Analysis > TDR

•To restart the TDR application GUI, click on Analysis > Start

TDR key

•To exit the ENA Option TDR application, press “[Analysis] – TDR”.

After pressing the TDR softkey to turn the application OFF, the

firmware will restart to exit the TDR mode.

TDR/TDT Mode: Setting Parameters

It is possible to mathematically remove the effects of a particular section of the

reflected response by specifying the gate range.

The gating results are

observed in the frequency

domain by coupling the traces.

The example on the left

couples the gate settings

between Trace1 and Trace2.

Observe the effects of applying gate on Trace1 in the time domain and observe the results on

Trace2 in the frequency domain.
