Fig.11 Intermodulation distortion (dim)(1.) and cross-modulation distortion (dcm)(2.) as a function of Po sync.

Typical values; VCE = 25 V; IC = 850 mA;− − −Th = 25 °C;Th = 70 °C; fvision = 860 MHz.

1. Three-tone test method (vision carrier −8 dB, sound carrier −7 dB, sideband signal −16 dB), zero dB corresponds to

peak sync level.

Intermodulation distortion of input signal ≤ −75 dB.

2. Two-tone test method (vision carrier 0 dB, sound carrier −7 dB), zero dB corresponds to peak sync level.

Cross-modulation distortion (dcm) is the voltage variation (%) of sound carrier when vision carrier is switched from

0 dB to −20 dB.
