The use of frequency synthesis provides complete frequency agility in the 54-550 MHz range using off-air or CATV (STD, IRC, or HRC) channel plans. The use of a superior SAW filter in the IF circuitry allows adjacent channel operation when used with other modulators or signal sources.

An EAS/alternate IF feature allows automatic or manual EAS/AST IF insertion.
