During the *Signal Generator Back-to-Basics Webcast*, hosted by Agilent Technologies, on 29 February 2012, we received a number of real-time questions from a broad audience. 

If one person asks - someone else will want to know the answer too - so we have captured various questions and answers and are posting them individually here, in this Forum, for your future reference and immediate enjoyment!

*Question: If you wanted to determine how much EVM a receiver could tolerate at a given error rate, how would you control a signal generator to increase the EVM of its output in a ramp fashion to see when the receiver's EVM tolerance was exceeded?*
