Oscilloscope Probing in Power Electronics – What to Use and Why
Power electronics designs have inherent measurement challenges. Proper probe selection and use is critical for operator, equipment and DUT safety and also has a large influence on the accuracy of the measurement. Join Teledyne LeCroy as we describe what high voltage and isolated probes are best suited to each measurement.
Part 1: How to Choose the Correct High Voltage Probe
Date: April 2, 2025
Time: 11:00AM Pacific | 2:00PM Eastern
Duration: 60 mins including live Q&A
In part 1, we’ll discuss how to choose the correct high voltage probe, taking into consideration the application and the accuracies required, and the safety of the operator, equipment, and DUT. The difference between the “right” probe and the “wrong” probe is usually not black and white, but more of a shade of gray.
Topics covered in this webinar:
- Important probe specifications
- Probe architectures, types and characteristics
- Probe fit to various applications
Who should attend? Any engineer who is probing in any type of power conversion system with floating voltages above 12 V.
What attendees will learn? Attendees will gain a thorough understanding of the different types of HV probes and how to choose the best probe for the specific application.
Presented by: Ken Johnson, Director of Marketing; Jon Shechter, Product Marketing Engineer; William Kaunds, Product Marketing Manager
Part 2: Real-World High Voltage Probing Comparisons – Highlighting Basic Specification and Performance Differences
Date: May 21, 2025
Time: 11:00AM Pacific | 2:00PM Eastern
Duration: 60 mins including live Q&A
In part 2, we’ll use basic probe comparisons with simple measurements on lower-speed high voltage signals to draw attention to the performance degradations of probes with seemingly “normal” specifications, and describe why these performance degradations occur.
Topics covered in this webinar:
- Comparison of “older” and more recent vintage HV differential probes from multiple manufacturers
- “Best-in-class” equipment from 20 years ago
- Price vs. performance – you often get what you pay for
- Instrument isolated inputs versus HV isolated probes
Who should attend? Any engineer who is probing in any type of power conversion system with floating voltages above 12 V.
What attendees will learn? Attendees will gain a better understanding of how to identify a measurement problem caused by a poorly performing probe or a misapplied probe.

Part 3: Real-World High Voltage Probing Comparisons – Specialized HV Optical Probes and 60V Common-mode Probes
Date: June 25, 2025
Time: 11:00AM Pacific | 2:00PM Eastern
Duration: 60 mins including live Q&A
In part 3, we’ll improve on our understanding of high voltage probing by using higher-speed signaling (consistent with GaN and SiC devices) and highlighting what can be expected from HV optical probes or other application-optimized probes. We’ll apply everything already learned in Parts 1 and 2, but add significant measurement challenges to the probes to further differentiate their performance capabilities and characteristics.
Topics covered in this webinar:
- HV optical probe topologies – how are they constructed?
- Performance tradeoffs of optical vs. electrical probes
- Optimized probes for 60 V common-mode applications
Who should attend? Any engineer who is probing in any type of power conversion system with floating voltages above 12 V.
What attendees will learn? Attendees will gain a better understanding of how to identify a measurement problem caused by a poorly performing probe or a misapplied probe.
