Practical Considerations for Reliable Characteriation of Electrical Devices

Date: Friday 13 October 2023

Time: 3am NZDT | 1am AEDT | Midnight AEST | 10pm AWST (Thurs 12th)

Various steps go into accurately characterising new devices, especially when measuring electrical signals, voltage, and current.

This webinar will cover these steps, discussing what’s necessary to ensure high-quality and repeatable measurements — particularly when characterising at cryogenic temperatures.

Lake Shore's Jason Chonko, the webinar's presenter, will discuss ways to:

• Reduce the impact of noise, self-heating, and other parasitics
• Simplify connections to the device under test, including ground connections
• Ensure simultaneous measurements when testing multiple samples
• Minimize ground loops and crosstalk on instrument cabling

By attending this webinar, you will learn:

• The importance of when to use shielding and guarding on fixturing and cabling
• How to identify and deal with common sources of environmental noise
• Single-ended vs. differential measurement techniques
• How to choose between a voltage or current source depending on the resistance of the device measured
• A new approach to performing DC and lock-in measurements
