Keysight’s new DDS source in the PNA and PNA-X Network Analyzers makes phase and group delay measurements 10 times faster with 30 times less noise in the trace.  Join Keysight Fellow Dr. Joel Dunsmore as he walks through short measurement demonstrations highlighting these new enhancements. 
Noise Figure Measurement Comparison Webinar
Original webinar date: February 8, 2022
In this webinar, Keysight Fellow Dr. Joel Dunsmore will show Noise Figure measurements on multiple instruments such as the Network Analyzer, Signal Analyzer, and the Noise Figure Analyzer.

This will be a direct comparison showing demonstrations on each of these solutions in the lab.
Distortion Characteristics
Demo: Distortion Characteristics
Original webinar date: June 30, 2021
In this webinar Dr. Joel Dunsmore will demonstrate distortion characteristics under CW Drive with two-tone intermodulation distortion.  With modulation drive, error-vector magnitude (EVM) and Adjacent Channel Power (ACP) will also be demonstrated.
Spurious Testing
Demo: Spurious Test
Original webinar date: June 16, 2021
In this webinar Dr. Joel Dunsmore will demonstrate close in carrier spurious, higher order mixing products, and spurious vs. LO drive level.
Noise Figure Measurements
Demo: Noise Figure Measurements on Converters
Original webinar date: June 2, 2021
In this webinar Dr. Dunsmore will demonstrate Noise Figure measurements on converters with embedded LO, mixers with external LO and high-gain considerations.
Power Dependent Measurements
Demo: Power Dependent Measurements on Converters
Original webinar date: May 19, 2021
One thing you want to know about your frequency converters is it’s gain compression or where the non-linear behavior starts. Join Keysight Fellow Dr. Joel Dunsmore as he gives a short 20-minute demo of this measurement on the PNA network analyzer with the enhanced DDS source.
