The method of multi-channel RF pulse creation is
presented here by the use of a set of independent
wave-form synthesizers. They can operate directrly at
Larmor frequency as high as 512 MHz. Up to 16 channels
with absolute phase coherency can supply pulses to
transmit amplifiers of scanners operating at magnetic
fields up to 12 Tesla.
