ELECTRICAL CHARACTERISTICS

T_AMB= 125°C (operating range 210°C to180°C), V_CC= 15V, (operating range14·5 to15·5V). Max and Min values are

guaranteed by either production test or design. They apply within the specified temperature and supply voltage ranges unless

otherwise stated.

NOTES

1. This is the nominal input level to provide the preset video modulation index for the selected standard. Any variation from the

nominal level will change the RF modulation index.

2. The actual clip level is set relative to the input video level. The level of 1·17V only applies if the video input signal is correctly

proportioned. The white clip circuit operates only when the AGC is disabled.

3. Measured at CH38 with R&S EMFP demodulator and UAF Video Analyser.

4. Measured at CH21 with R&S EMFP reference demodulator and UAF Video Analyser. Synchronous demodulation.
