So, here I sit looking at spectra and all points from all machines (select any machine file database) and they all have the same baseband frequency of 500 Hz.

CSI v 4.92 -- anyone have an idea how to get this thing back?

Sam,

I'm not sure what you are referring to when you say "same baseband frequency of 500 hz".

Are you looking at a spectral graph of multiple points on a machine? If so then it will create the graph to the highest fmax and display all points on the same horizontal scale. The actual fmax of the reading does not change.

Does that help? If not, get another cup of coffee, stop to chat with some co-workers and come back and we'll give it another try.

I just opened some files of 2000 Hz baseband and some 5 kHz - or select any file, 500 Hz full scale is all you get anywhere you look.

A shot in the dark. Would your Fixed Frequency Scale Enabled be checked off under Axis options?

I think Wally has a winner.

Somehow - YES!

It was not obvious though. I searched for a checkbox and couldn't find one anywhere or not in an ovbious location. It is not with the plot options or Horz or Vert scaling or the like.

The break and coffee worked ---- now to go home and have sack time --- head weights an extra 20# of yeller buggers.

Thanks to all .... just brain damage on my end!
