SAW filtered NTSC MONO audio/video mini modulator.
Features
- 135-Channel Range 54-860 MHz
(CATV 2-135) - >45dBmV min adjustable output
for optimum carrier-to-noise
performance - Compatible with most manufacturers mini-modulator chassis
- State-of-the-art digital phase locked-loop (PLL) design guarantees precise frequency locking for
solid drift-free operation - Microprocessor control enables quick digital push-button channel
selection for ease of installation, configuration, and improved system uptime - SAW (surface acoustic wave) filtered for superior adjacent channel performance enables drop-in channel expansion
- In-band carrier-to-noise ratio >65dB ensures superior picture quality
- Automatic selection of aeronautical offsets (12.5kHz, 25kHz) for trouble-free configuration
- Front panel access to controls enables easy setup
