• 319730 04/27/10 00:03 ZAFAR AHMED Cavities signal is good in RHRS but not in Parity DAQ.

I guess the bad cavities today are due to the low-current running and
that we forgot to restore the high-current gain settings and phases.

Regarding the problem we had Sunday in low-current mode:  No signals
were seen in the counting DAQ.  This was because the cable fell out
of the Fastbus.  I think Ahmed has fixed it.

We should always check high-current with spot++.  Plotting cavities
versus striplines with counting mode should show an ellipse.
(It's not a line because there's a phase.) If we don't get this
well-known result there is a problem with the cabling or with
the high-current setup.  This is a basic checkout that should be
done before a Qsq measurement in the future.
