A real time tunable electrooptic rf filter is demonstrated using a multichannel total internal reflection modulator to spatially filter the output of a Bragg cell. The demonstrated filter has a bandwidth to resolution ratio of 28. This ratio can potentially be increased to over 5000 with a like number of individually resolved frequencies.
