I just updated to REW v5.20.2 today (I was probably a number of releases behind), and I noticed that the amplitude column is now exported with very coarse rounding (when using the "Export measurement as text" option).
The Y axis values are rounded to the nearest 0.1dB. This was not the case in the version of REW I was using previously (can't remember the version number), so it must be a relatively recent change.
Here are the first few lines of a frequency response file (exported from an older version of REW) vs. the same data re-exported from the current version of REW:
Original:
Exported from the current version of REW:
This makes exported measurements have a noticeable stairstep effect. Here's a zoomed-in part of a frequency response graph (in blue) compared to itself after exporting and re-importing (in red):
I hope this can be fixed soon.
