Re: Problem setting spectral width

With respect to the attached portions of the message about problems
changing the spectral width, the AMX users were very lucky that they got
error messages when changing the spectral width. We have ARX spectrometers
and the manifestation of this "feature" was that it happily changed the
spectral width and simultaneously shut down the digitizer to 2 bits.
Needless to say this was a bit unfriendly. However, we had no warning of
the problem. I had that version on for a couple of weeks before I realized
what it was doing. Reducing the spectral width by selecting SW-SFO1 from
displayed data did not introduce the error; typing in a value for SW did.
Once I realized what was going on, I permanently cured it by reading in any
default parameter files that we keep, selecting "DIGTYPE" (even though the
correct choice was displayed) and restoring the parameter files with the
wpar command. In a busy multi-user environment like we have I would not
even be able to guess how much time was wasted before I discovered this was
going on.
