Mastering EVM: Optimizing Your Signal Generator
IEEE North Jersey Section Co-sponsors the event
- When it comes to EVM, there is no single number to characterize performance, and until now, no simple way to get the best EVM performance. There are many controls to optimize generator quality: ALC; frequency response; IQ modulator; and gain stages. Setting up your VSG can be a complex and challenging task. Does it make sense to force test engineers to be generator designers? Thankfully the answer is no. Many modern VSGs now include “Optimize EVM” features. The firmware will automatically optimize itself for the best EVM. Part three of our “Mastering EVM” webinar series explores how to optimize your signal generator to meet your EVM requirements.

Mastering EVM: Optimizing Your Signal Generator
This webinar is intended for engineers who work on the signal generators to meet the EVM requirements.
You may be surprised to find that your vector signal generator (VSG) is very similar to an amplifier or modulator you are testing in your lab. Signal generators are traditionally characterized by RF parameters like output power; P1dB; ACLR; harmonics. Modulating a signal brings additional modulation requirements like IQ imbalance; IQ mismatch and phase noise.
When it comes to EVM, there is no single number to characterize performance, and until now, no simple way to get the best EVM performance. There are many controls to optimize generator quality: ALC; frequency response; IQ modulator; and gain stages. Setting up your VSG can be a complex and challenging task.
