Abstract: All the decoupling schemes of Varian have unique properties (especially in the width and perfection of decoupling). Each has attributes that suit different spectroscopic tasks. The Varian waveform generator incorporates the power and the flexibility, with a right design to meet your every of modulation need. Each and everychannel in a UNITY plus system has its own PROM controlled Phase Modulator.This PTOM contains a variety of decoupling schemes. It provides the user with GARP and WALTZ ("optional"), XY32, MLEV16, noise, cw, square wave, and sweptsquare wave, as well as access to the optional WFG customer -input text-file-driven decoupler schemes.
