It would be useful for some test situations to have the level you set on the generator also set the measurement chirp level. The reverse is already true.
And if that were an option, then a "Measure Now" button that triggers a measurement without going through the setup/options screen first would be nice. My clicker finger would be glad to avoid as my clicks as possible.
A one-click SPL meter cal would also be a nice option, bypassing the cal result/confirmation windows. It takes 3 clicks to cal the meter now, one would be excellent.
You see where this is going. It's not me being lazy, I'm really hurting my clicker finger with so many clicks!
Possible bug: I noticed that sometimes the SPL meter won't indicate an input even though it has one and the meter is turned on. Closing and re-opening the meter fixes that. The level meter conflicts with the SPL meter of course, and the level meter wins. I don't use the level meter much, but use the SPL meter and re-cal it quite a bit, usually with the Generator window up.
Combining the SPL meter and the generator in a single "test bench" window would be really slick...and avoid clicking to focus windows.
The next one is pretty out there...have an option to generate a group of closely-spaced HF tones, more than two, more like 20-30 or more. The technique is covered in Deane Jensen's "Spectral Contamination" AES paper. He used a programmable arbitrary waveform generator and an ancient hardware FFT plus some filtering to reveal distortion behavior that is not generally detectable with THD and IMD. I'd like to experiment with his technique using modern hardware and REW, but the limitation is being able to generate the multi-tone test signal. But I realize that one may not even make it to the list, but I thought I'd toss it out there.
Thanks for all your hard work!
