MEASUREMENT METHOD
Input no more than 300-mV_p-p as a burst signal to chroma input pin (TP45).
Measure the DC voltage difference (vBH) between the H blanking period and picture period of the B-Y
output pin (TP47).
3) Measure the DC voltage difference (vRH) between the H blanking period and picture period of the R-Y
output pin (TP48).

1) Input no more than 300-mV_p-p as a burst signal to chroma input pin (TP45).
ON 2) Measure the picture period DC voltage V_B of the B-Y output pin (TP47).
3) Measure the picture period DC voltage V_R of the R-Y output pin (TP48).
1) Use the following formula to calculate the difference (V_RB) between the voltage axes from the following

formula using the values obtained in C₁₂ above.
V_RB = V_R − V_B
1) No signal input to the chroma input pin (TP45) (set SW₄₅ to A).

2) Observe the CW output pin (TP50) and measure the output frequency X_f.
Note 1: Where the bus data are not specified, set the preset values.
Note 2: Ensure the sync signal is always input to TP38 (SYNC IN).
