An adjustable slew rate amplifier (26) in the input stage of an amplifier circuit (10) helps reduce offchannel frequency splatter. In instances where test sequences are input to an amplifier circuit that are used to measure maximum permissible input levels to the amplifier (34), inclusion of a low slew rate amplifier in the input loop further prevents the production of offchannel frequency splatter caused even by the input test sequence. The adjustable slew rate amplifier (26) is run at full slew rate, providing full-bandwidth amplification, during periods of normal circuit operation.
