eML Monaural Modulator (MM)

video and audio television modulator, fixed output channel

SAW filtered

synthesized visual and aural carriers, synthesized frequency offsets

high carrier-to-noise ratio

low spurious and low-out-of-band noise

very compact, 12 modulators in 1U (1.75") chassis

other module types e.g. SM, PM can be accommodated in the same chassis
powered by redundant MPS-9 or non-redundant SPS-9
ordering information: MM-xxx where xxx is the channel number
