ON
1)
Input a rainbow signal (signal C-1) to the chroma input pin (TP45).
Burst : chroma = 300 mVp-p : 300 mVp-p
2)
Measure the demodulation angles θB’ and θR’ in the outputs with the tint set to the maximum
(subaddress (03H), data (FE)). Calculate θBmax and θRmax by the following formulas.
θBmax = θB’ θBcnt
θRmax = θR’ θRcnt
3)
Measure the demodulation angles θB” and θR” in the outputs with the tint set to the minimum (subaddress
(03H), data (00). Calculate θBmin and θRmin by the following formulas
θBmin = θB″ θBcnt
θRmin = θR″ θRcnt

ON
1)
Input a rainbow signal (signal C-1) to the chroma input pin (TP45).
Burst : chroma = 300 mVp-p : 300 mVp-p
2)
As in C2, measure the amplitudes VBp and VRp of the B-Y output pin (TP47) and R-Y output pin
(TP48) when the 5-V VCC is set to 5 V + 0.3 V. Calculate the amplitude ratios BVp and RVp when the 5-V
VCC is set to 5 V.

Identification Sensitivity
B
ON
1)
Input a rainbow signal (signal C-1) to the chroma input pin (TP45).Burst : chroma = 1 : 1
2)
Gradually reduce the input signal amplitude from 100 mVp-p. When the B-Y output pin (TP47) signal
disappears (when the current is DC), measure the input signal amplitude vCB.
3)
Gradually increase the input signal amplitude from 0 mVp-p. When a demodulation signal appears on the
B-Y output pin (TP47), measure the input signal amplitude vBC.
C9
Bus Read Identification
B
ON
1)
Perform the same tests as above while observing the bus read : When the input signal amplitude is vCB,
check that the first bit is set to 0 (bCB).
When the input signal amplitude is vBC, check that the first bit is set to 1 (bBC).
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).
