ACC2 ACC characteristic 2

1. Input SG.E (input level: -18 dB) to pin 46.

2. Measure the pin 18 output amplitude.

3. ACC2 is defined as follows.

OV chroma overload characteristic

1. Input SG.E (eb = 800 mVp-p: chroma + 3 dB) to pin 46.

2. Measure the pin 18 output amplitude.

3. OV is defined as follows.

VikN killer operation input level

1. Input SG.E (variable level) at input level 0 dB to pin 46.

2. While monitoring the pin 18 output amplitude, lower the input level, and measure the input level when the output

amplitude vanishes.

KillP hue remaining with killer

1. Input SG.E (level: –40 dB) to pin 46.

2. Measure the pin 18 output amplitude.

APCU APC pull-in range (upper)

APCL APC pull-in range (lower)

1. Input SG.E (feb = fec = 3.579545 MHz) to pin 46.

2. After raising the frequency until the output from pin 18 vanishes, lower the frequency, and take the point at which

an output appears to be fu.

3. After lowering the frequency until the output from pin 18 vanishes, raise the frequency, and take the point at which

an output appears to be fl.

4. APCU and APCL are defined as follows.

APCU = fu – 3579545 Hz

APCL = fl – 3579545 Hz

R/BN demodulation ratio R-Y/B-Y

1. Input SG.E (eb = single chroma = ec + 50 kHz) to pin 46.

2. Take the pin 18 output amplitude when I

2C data is 11H D4 = 1 to be VRY.

3. Take the pin 18 output amplitude when I

2C data is 11H D5=1 to be VBY.

4. R/BN is defined as follows.
