I just followed your advice ( thus the quote ) for stepped sine measurement to be better used for distortion...
As for v5.40...
I am running a MBP9,1 with Macos 10.13 / 10.14
and now you want a higher Macos to work with REW ?
Please make it work on 10.14.6
since I specially upgraded to 10.14.6...
How should I interpret the distortion figures in these measurements - also stepped sine...
The Motu 896mk3hd was measured with a loopback @ 48, 96 and 192 kHz
Distortion figures in stepped sine measurements go way up in the highs...with higher sampling rates
Thanks for hints

Hmmhh...
If I start the generator and start RTA after, the clock ∆ goes down to ca. 1.8 ppm and then struggles
If I start RTA first then the generator, the clock ∆ goes down all the way to 0.2 ppm and no flickering...
Is this only on my rig ?
Soundpath :
Motu analog out 1+2 out ( defined as output channel mapping 3+4 in REW )
Motu analog in 5+6 as input
timing ref analog out 2
loopback input analog 6
wrong ?
...if such dropouts happen, I would hear them for sure, not ?
I can listen to the loopback and can't hear anything...
I can re-check but am alsmost sure the clocks are the same everywhere...
