IMD testing? Where?

[bcodemz]

Looking at the release notes for V5.30 there is mention of IMD TD+N bug fixing. Do we finally have IMD testing in REW now? But I can't find it. If we do, where is it? This is a very much appreciated new feature.

Thanks

In the Signal Generator:

19KHz and 20KHz multitone:

There is also an IMD vs Level ioption n the Stepped sine test.

This is just what I was looking for, thank you!

If I may, I feel the stepped sine test should be part of the measurement tab rather than RTA. Nobody knows about the IMD and multi tone testing because it's hidden under RTA, not where one would look when they look for measurement testing. Given the endless confusion on distortion due to harmonic distortion being a very insufficient test to capture all distortion generation mechanisms, and how IMD and multitone distorting testing is far better, it would be huge if IMD and multi tone distortion can get more spotlight on REW, especially when you have already taken the difficult step of implementing it. It deserves far more recognition and use.
