4. Measure the differential gain (DG) and differential phase (DP) using a vector scope with a 5-step function wave
5. To measure LS, input a 5-step function wave and measure the ratio of the sync level (S) to the luminance level (Y).
6. To measure clock leakage (Lck), measure the 4fsc (14.3 MHz) component in the output signal with a spectrum
7. To measure the noise level (N
8. The following formula is used to calculate the output impedance (Z
9. To measure the delay time (TD), measure the delay time of the output signal to the input signal. In this measurement,
