Test Conditions for Color Difference Block 1: YUV input and matrix
Common Test Condition for Color Difference Block 1: YUV input and matrix
1. SW1 = B, SW2 = B, SW20 = ON, SW33∼SW39 = A, SW54 = OPEN, SW56 = OPEN
2. Transfer BUS control data with preset values.
3. Turn ACB operation switching to ACB OFF (0), and turn high blight color OFF (0).
4. Input sync signal [must be sync with input signal for testing except Sweep.] to #14 (sync input), and set SYNC-IN-SW to 1.
Note No.

B 1. Set Y mute ON (P-MODE: Y-MUTE, 001), brightness to center (10000000), color to center (1000000),
unicolor to maximum (1111111).

2. Input 2T pulse signal to TP4 so that #4 amplitude is 423 mVp-p.

3. Monitor #41 output waveform. When color SRT peak frequency is 4.5 MHz (0), measure gradients of color
SRT gain for minimum (00), center (10), and maximum (11) that are SB00MIN, SB00CEN, and SB00MAX as
shown in the figure below. Set SB00MIN to 0dB, calculate GS_B00CEN = 20 × log (SB00CEN/SB00MIN) and
GS_B00MAX = 20 × log (SB00MAX/SSB00MIN).
4. When color SRT peak is 5.8 MHz (1), measure gradients of color SRT gain for minimum (00), center (10), and
maximum (11). Calculate G_SB01CEN and G_SB01MAX.
5. Input 2T pulse signal to TP5 so that #5 amplitude is 300 mVp-p.
6. Monitor #43 output waveform. When color SRT peak frequency is 4.5 MHz (0), measure gradients of color
SRT gain for minimum (00), center (10), and maximum (11) that are SR00MIN, S_R00CEN, and S_R00MAX as
shown in the figure below. Set SR00MIN to 0dB, calculate GSB00CEN = 20 × log (SB00CEN/SB00MIN) and
GSB00MAX = 20 × log (SB00MAX/SSB00MIN).
