R&S RTB2004 - FFT bug with scale markers

[javadesigner]

On an R&S RTB 2004 (with latest 02.300 firmware), I'm seeing various wonky FFT related behaviors.

For example, changing the horizontal scale in FFT mode makes the graticule markers display wrong! Instead of "mV" and "mS", now they just show "m".

Please see attached screenshot. This can't be expected behavior so many years later after its release can it ?

Hi.
I still use 02.202, and I don't have that problem.

Thanks - FYI it doesn't happen all the time, seems to be quite random when it starts doing this.
