Greetings
Recently, there has been growing interest in experiments
that require the 2H lock to be interrupted and the field to be
held under program control. This is essential when doing 2H
decoupling work, and very useful for gradient pulse experiments.
The AM and AMX (prior to digital lock) spectrometers do not
have provision to do so.
We have modified our AM and AMX systems to add this feature.
The mod. interfaces with the Lock reveiver and the PFP unit, and
is controlled by one of the extra control lines available.
I can supply anyone interested with the technical details of the
modification. I can also supply the hardware as a kit.
