Input Signals and Test Conditions
Unless otherwise specified, the following conditions apply when each measurement is made.
1. VIF, SIF blocks: No signal
2. Deflection Block: Horizontal/vertical composite sync signals are input and the deflection block must be locked into
the sync signals (Refer to the Deflection Block Input Signals and the Test Conditions).
3. Bus control conditions: Set the following conditions unless otherwise specified.
Y Input is 42 Pin (EXT-V IN),
C Input is 44 Pin (S-C IN)
(Video SW=1, C.Ext=1)
Other DAC except the above-mentioned conditions is all initial conditions.
4. Y Input condition: No signal unless otherwise specified.
(Sync is necessary to obtain synchronization).
5. How to calculate the demodulation ratio and angle:
B-Y axis angle = tan-1(B(0)/B(270))+270°
R-Y axis angle = tan-1(R(180)/R( 90))+90°
G-Y axis angle = tan-1(G(270)/G(180))+180°
B-Y axis amplitude Vb = SQRT(B(0)*B(0)+B(270)*B(270))
R-Y axis amplitude Vr = SQRT(R(180)*R(180)+R(90)*R(90))
G-Y axis amplitude Vg = SQRT(G(180)*G(180)+G(270)*G(270))
