Customer reported that they could not lock (using 2H) or gradient shim. Looked at 2H RF path and good signal coming out of console to probe. Problem must be on receive side. Swapped the following parts for troubleshooting: 2H Diplexer Lock Preamp 2H RF Relay (verified operation) 2H Filter (bypassed) Believe issue is the Mixer…

Lineshape does not meet spec. Needs 3D Gradient shimming. Found that the upper barrel was not centered in magnet field. Re-centered upper barrel. Performed 3D gradient shimming successfully. Obtained lineshape spec after RT shimming. Performed H1 and C13 performance specs, all passed. Default shims and power level vales saved. New gradient map saved.
nstalled DOTY HX probe. Lineshape was marginal, as was S/N. Had to install sample from below like a solids probe. Was unable to get it to work with the upper barrel and sample eject because the probe is longer and has too much air leakage. See message below sent to DOTY. Judy, I was assisting…
