Teledyne LeCroy Webinar – Taking the TDR for a Spin: Interpreting Impedance Profiles

Date: Wednesday, August 7th
Time: 11:00 AM Pacific | 2:00 PM Eastern


Presenter: Eric Bogatin, Dean of the Signal Integrity Academy



The TDR measures instantaneous impedance. When the interconnect is uniform, we can interpret the instantaneous impedance as a characteristic impedance. When it is not uniform, the instantaneous impedance depends on the rise time of the TDR. We can still use the impedance at a rise time as a figure of merit.

In this webinar, you will learn how to interpret a TDR’s measured instantaneous impedance profile in terms of the interconnect’s characteristic impedance and time delay, and the location of impedance discontinuities. We’ll look at a variety of cables and PCB interconnect structures.

Teledyne LeCroy 2-Part Webinar: Protocol Compliance Testing & Physical-Layer Testing

Date: Tuesday, July 23rd & Thursday, July 25th
Time: 11:00 AM Pacific | 2:00 PM Eastern


Presenters: Gordon Getty, Technical Marketing Manager and Dr. Patrick Connally, Product Marketing Manager


Before the official compliance program kicks off in August, get a masterclass in PCI Express 4.0 from the only company that covers all the required compliance tests – from electrical through Link layer and Transaction layer.

Teledyne LeCroy’s PCI Express physical-layer and protocol test experts will break down each test, explaining the background theory, how the test procedure works, how passes and failures are determined, and how to track down and debug problems.

Part One will cover Protocol Compliance Testing, Part Two will cover Physical-Layer Compliance Testing.

Teledyne LeCroy Webinar: Beyond the TDR

Date: Wednesday, july 17th
Time: 11:00 AM Pacific | 2:00 PM Eastern


Presenter: Eric Bogatin, Dean of the Signal Integrity Academy


Time Domain Reflectometer (TDR) displays the instantaneous single-ended or differential impedance profiles of an interconnect and the location of discontinuities. While this is valuable information, there is additional information we can extract by expanding to multiple ports and looking at not just the differential impedance, but also the common impedance and even the location of cross talk and mode conversion.

In this free webinar, Teledyne LeCroy introduces the value of looking at multi-port and mixed mode TDR and impedance measurements: the best measurement practices and how to analyze the results.

Orolia Webinar: Advanced Simulation Test Systems for Controlled Reception Pattern Antennas

WEBINAR: Measuring and Debugging CAN/CAN FD Signals with an Oscilloscope

Date: Thursday, June 27th
Time: 1:00 PM EDT | 10:00 AM PDT

Lisa Perdue, simulation product manager, Orolia; Stéphane Hamel, director, testing, Orolia; Dean Kemp, defense segment manager, NovAtel

Controlled Reception Pattern Antennas (CRPAs) are advanced, multi-element antenna solutions that are designed to protect a GNSS/GPS receiver from jamming sources. When combined with antenna electronics, they form an Anti-Jam Antenna System (AJAS). These systems utilize several available technologies and vary in the number of elements.

This webinar will cover the basics of AJAS and CRPA, and the methods used to test them. Details on simulation system configurations, calibration techniques, and use case examples will also be presented.
