EXCITERS & MODULATORS

EMCEE supplies a wide selection of modulators for all world analog and digital television formats. 

Our composite output analog modulators are rich with features and provide pristine audio and video baseband modulation for clear and crisp video broadcast pictures.  Ask about  our EMEX1 exciter for high power broadcast application and integration.

For ATSC digital applications, choose our fully ATSC A.53 compliant DRP-1000.  It accepts an ASI or SMPTE 310 input and provides an error free digital transport stream output at an I.F. frequency of 44 MHz.  When used in translator mode it also provides  wide band RF tuning and digital de-modulation.

For MMDS digital video applications, we offer a robust and low-cost  64QAM modulator.  For more demanding applications a modulator with Ethernet networking and SNMP is available.

The following chart is provided to select the proper digital modulation format for your area.
