|
The VCom A2020 Agile CATV Modulator offers performance, flexibility and reliability to meet the most demanding requirements. It accepts video and audio baseband inputs and provides a modulated visual and aural carrier on any NTSC channel (or PAL - optional) in the 45 to 550 MHz and 550 to 850 MHz ranges.
Features:
Versions available for NTSC, PAL B/G, I and D/K
RF level output:
+50 dBmV VHF model 45 to 550 MHz
+50 dBmV UHF model 550 to 850 MHz
Front panel dip switch control
T7 to T13 (7 to 43 MHz) channel operation (extended operation)
Fully quartz synthesized visual and aural carriers exceed FCC required intercarrier stability
SAW filtering ensures broadcast quality RF performance
Carrier to noise does not degrade with decreased RF level adjustment
Defeatable audio pre-emphasis or aural carrier for BTSC stereo compatibility
Frequency offsets automatically selected for FCC/DOC requirements (fully synthesized)
Ultra low noise performance -72/-92 dBc
80 channel system noise performance £¾55 dBc/4 MHz
Micro processor based diagnostic routines ensure specifications for correct operation
Low cost
Space efficient - 8 modulators require only 4U (7" rack height)
High reliability, state of the art design using MMIC, microstrip and SMT technology
Durable design is reflected in stainless steel chassis
