What Have You Been Missing In Your Pulsed VNA Measurements?

12/17/2013 ,08:00AM ,1 hour

Overview: This webinar will describe historical pulse measurement methods used by Vector Network Analyzers and the associated trade-offs. Then it will introduce the latest VNA pulse measurement capability based on a new, innovative, high-speed digitizer architecture. This new architecture enables VNA users to examine additional aspects of pulse characteristics that were previously unavailable. A number of the benefits will be shown, such as employing higher resolution sampling to investigate pulse edge effects and intra-pulse behavior, using longer record lengths to monitor time-variant events over greater spans of time, and the ability to adjust test parameters with the ability to see the response in real-time.

Who should attend:

  • R&D engineers involved with development of component and systems, including T-R modules for radar systems
  • Engineers needing to perform pulsed I/V testing for thermal reasons as might occur in an on-wafer device characterization situation or when testing higher power amplifiers in a bench-top scenario

What you will learn:

  • How to get a higher time resolution view of S-parameter data to spot anomalous intra-pulse behavior and rise/fall time issues
  • How to measure how pulse behavior changes over time due to amplifier or transmitter warm-up effects
  • How to compensate for DUT time delays when making pulsed measurements and make accurate measurements
