Calculate the pin 41 (H.out) frequency variation rate when the voltage on pin 45 is varied by
±0.05 V with
a horizontal oscillation frequency of 15.734 kHz.

Measure the phase difference SPH1 of the pin 41 (H.out)
waveform in relation to the pin 49 (HD.out) waveform
when a 50 Hz composite video signal is applied to TP52.
Measure the phase difference SPH2 of the pin 45
waveform in relation to the center of the input signal’s
horizontal sync signal Also, apply a 60 Hz composite
video signal to pin 52 and measure SPH3.
