Dear AMMRLers,
First of all, thanks for quick replies to Arnold, Eric, Jerry, Joseph,
Michael, Neil, Philip, Sauriol, Scott, Shaoxiong, and Virgil.
The problem was due to the PTS as some replies pointed out. With a PTS from
another instrument, wobble behaved normal.
Do you have vendors to recommend for PTS repairing?
Cheers,
Jerry
Original Inquiry:
=====================
Dear Colleagues,
I am putting an AVANCE DRX400 console together for our ODNP instrument and
running into a wobble problem. The tuning curve is there in the very
middle, but there are washout regions 20MHz apart and 16MHz wide. Has
anybody seen this before? What could be the possible reasons? I appreciate
your help.
The console is controlled by Topspin 1.3 pl8 on the WIN XP computer.

Jerry
