Features
• Heterodyne conversion system, in conjunction with the use of a SAW filter, insures optimum vestigial selectivity for adjacent channel headends.
• Accepts standard (sync. Negative) polarity video at 0.7 to 1.5 Vp-p level.
• All level controls are conveniently located on the front panel.
• High output power to +55 dBmV.
• A convenient monitor port is provided.
• Pre-emphasis may be disabled for special applications like an external stereo generator.
• All aeronautical channels are offset positive with a tolerance of ± 5 kHz as required by FCC rules.
• Rear Panel AC line convenience outlet.

RF
Frequency Range: 54 through 552 MHz. Channels Available: CATV Channels 2 through 78 and 95 through 99 FCC Frequency Offsets: All aeronautical channels offset positive with a tolerance of ±5 kHz. Output Level: +55 dBmV minimum, (typically adjustable from +43 to +55 dBmV). Output Impedance: 75 Ohms; return loss of 14 dB nominal. A/V Ratio: Audio Carrier -20 to -12 dB referenced to video carrier, adjustable. Frequency Stability, Visual: Within ± 10 kHz of assigned channel frequency. Within ±5 kHz of
assigned channel frequency on FCC offset channels. Aural Intercarrier Frequency: 4.5 MHz, ± 5 kHz. Spurious Outputs: -60 dBc minimum, measured at -15 dB A/V ratio and with modulator
output level of + 55 dBmV. In-Channel C/N: Better than 60 dB. Broadband Noise: -95 dBc @ ± 30 MHz or greater spacings. (Specified levels are referenced
to the video carrier and measured in a 4 MHz bandwidth.)
Video
Input level for 87.5% modulation: 1 Vp-p ± 3 dB, manual gain adjust with front panel control. Input Impedance: 75 Ohms, return loss of 18 dB minimum. Frequency Response: Flat ± 2 dB from 30 Hz to 4.2 MHz. Video S/N: 60 dB minimum, luminance weighted. L/C Delay: Within 50 nanoseconds of 0 nanoseconds L/C delay (complies with
FCC rule 76.605). Differential Gain: Less than ± 5% (10 to 90% APL). Differential Phase: Less than ± 5 degrees (10 to 90% APL).
Audio
Input Level for 25 kHz Peak Deviation: 175 mV rms minimum. Manual gain adjustment with front panel control. Input Impedance: 10K Ohms, unbalanced. Pre-emphasis: 75 m Sec. (may be disabled with internal jumper change) Frequency Response: 40 Hz to 15 kHz, ±1.5 dB, referenced to 75 m Sec. pre-emphasis curve.
4.5 MHz Intercarrier Stability: ±5 kHz, 0 degrees Celsius to + 50 degrees Celsius. Total Harmonic Distortion: 1.5% maximum. Hum and Noise: -60 dB minimum, referenced to 25 kHz peak deviation.
