REW Measurement sweep levels inconsistency

[AustinJerry]

In the most recent REW betas, I notice that the Measurement Level default is 0dBFS. While I can't be sure, I believe earlier versions had the default level set to -12dBFS.

Regardless, for my first measurement, I manually change the default to -12dBFS, a level I am more comfortable with. I the run the measurement sweep for the LFE channel and get a maximum measurement level of 89dB, with a 21.4dB headroom. I then immediately run a second measurement without changing any setting, and this time the maximum measurement level is 101dB, with a headroom of 10.1dB. The difference between the two is 12dB, which leads me to believe something is amiss with how the measurement screen is seeing the desired output level that I set. Is this a known issue or expected behavior?

The default level is -12 dBFS. If the signal level the generator is already set to before running the sweep is different there is a bug that can change the measurement level to that level after the sweep ends, but it still shows the original level on the measurement dialog. That bug has been fixed for the next beta, in the meantime open the signal generator and set the output level for whatever signal it opens on to your desired sweep level.

Thank you, John!
