If themodulation mode is very narrow, the modulation fre-quency is 600Hz. If the modulation mode is narrow, themodulation frequency is 1200Hz.Flat cable (36-pin) about 256mm (E37-0979-05)ANT Jig for BPF adjustment (E30-3418-08)Fig. 1Fig. 2Fig. 3BPF center frequency (Production default):384MHzPass bandwidth: ±2.5MHz at 3dBCenter frequency: 49.95MHzPass bandwidth: ±7.5kHz at 3dBCenter frequency: 49.95MHzPass bandwidth: ±3.75kHz at 3dB3dB max.2.5MHz 2.5MHz3dBmax.7.5kHzMorethan55dB30kHz 30kHz7.5kHz3dB max.3.75kHz3.75kHzMorethan35dB12.5kHz 12.5kHz
