The Federal Communications Commission requires that cable system modulators, which operate in the aircraft communications and navigation bands, are offset in frequency by 12.5 kHz. The A860 PLL oscillator is factory set to comply with FCC requirements for frequency accuracy (±5 kHz) in the aeronautical communication and navigation bands. - Page 7 Signal Combining Methods The output levels of the modulator should be the same as the output of the off-air strip amplifiers. The A860 modulators are usually combined with either the DSP806 channel processors, or XBS series strip amplifiers.
