1)
Input a 3.58-NTSC rainbow (C-4 signal) burst/chroma signal with the same
burst/chroma amplitudes to the chroma input pin (TP54).
2)
Observe the BUS READ mode (5
th and 6th bits of the 1st byte).
3)
Switch the Indent sensitivity (set the subaddress (10) data low (C0) and high (D0))
and perform the following measurements.
4)
Increase the input signal amplitude from 0 and measure the input signal amplitude
at the switch to 3.58 NTSC mode.
(LOW (C0): vNCL, High (D0): vNCH)
5)
Lower the input signal amplitude from 100 mVp-p and measure the input signal
amplitude at the deviation from 3.58 NTSC mode.
(LOW (C0): vNBL, High (D0): vNBH)

1)
Input the signal C-1 to the chroma input pin (TP54).
(signal amplitude
= 50 mVp-p).
2)
When the subaddress (10) data are f0 = 3.58 MHz (00) and f0 = 4.43 MHz (60), and
subaddress (18) data are (38), connect 1.5 k
between the VI output pin 6 and the
5 V-VCC and observe the VI output pin 64.
3)
Measure the output amplitude when f0 = 3.58 MHz and calculate the gain in
decibels from the input (GFC3).
4)
Measure the output amplitude when f0 = 3.58 MHz ± 500 kHz and calculate the
gain in decibels from the input
(
+500 kHz: GFH3, 500 kHz: GFL3).
5)
Measure the output amplitude when f0 = 4.43 MHz and calculate the gain in
decibels from the input (GFC4).
6)
Measure the output amplitude when f0 = 4.43 MHz ± 500 kHz and calculate the
gain in decibels from the input
(
+500 kHz: GFH4, 500 kHz: GFL4).
