Abstract: All new UNITY systems are equipped with computer-controlled 63 dB attenuators on the observe and decouple channels,as well as with linear amplifiers and T-R switch preamplifiers.
The combination of these elements means that the capability for performing shaped pulse experiments is inherent in all UNITY system.
There does exist a routine in/unmr/psg named shape-pulse.c,which generates Gaussian,half-Gaussian,and hermit pulses for attenuators,and this routine is documented in the source code of the routine.

Key words: NMR, Shaped Pulses, Attenuator
