28 cxa1810aq/ar detailed explanation of measurement method (1) demod lpf frequency characteristics measurement using the cxa1207a as a modulator, the configuration for sg41 is shown below. first, without inputting sg54, adjust v car so that the y rf out (pin 43) output frequency of the cxa1207a is 5mhz. use v caro for the v car voltage. next, apply v caro + 500mv, measure the y rf out (pin 43) output frequency fo of the cxa1207a, and then calculate the mod gain using the following equation. gmod = fo (mhz)? (mhz) 500 (mv) the compensation values are derived from gmod and from gdemod1 and gdemod2 of measurement nos. 57 and 59. standard mode compensation value : g c1 = 20log [g mod (mhz/mv) g demod1 (mv/mhz)] hi-8 mode compensation value : g c2 = 20log [g mod (mhz/mv) g demod2 (mv/mhz)] next, in order to set the sg41 carrier frequency, adjust v car so that the y rf out (pin 43) output of the cxa1207a in standard mode is 4.8mhz and in hi-8 mode is 6.7mhz. in the above state, measure the i/o gain for the sg54 (200mvp-p/300khz) input and p7 (pin 7 demod out), with the gain for standard mode being g lpf10 and for hi-8 mode g lpf20 . using these measured values and compensation values, the low frequency gain for demod lpf is determined using the following equations: standard mode : g lpf11 = g lpf10 - g c1 (db) hi-8 mode : g lpf21 = g lpf20 - g c2 (db) c x a 1 2 0 7 a f m m o d r e c m o d e s w 4 1 y r f i n l i m d e m o d l p f c x a 1 8 1 0 a t o b e m e a s u r e d c a r 1 4 7 0 0 4 7 0 0 s g 5 4 v c a r ( s g 4 1 ) y r f o u t 5 4 4 3 4 1 7 p 7 d e m o d o u t

(3) measurement of gain difference between pb acc channels the acc amplifier in the cxa1810a has a built-in 4-channel time constants, and those time constants can be switched by swp (pin 46) input. in addition, in ntsc playback chroma signal processing, pi return occurs in the swp (pin 46) input for low interval. in this measurement, the signal k, that is phase-inverted each 1h, is input to pbc in (pin 45) for the low interval of swp; the continuous wave of the signal is input for the high interval of swp. in this case, measure each channel level v 1 , v 2 , v 3 , and v 4 of output p63 (pin 63 c out) and calculate the gain difference between channels using the following equations: d gch12 = v 2 v 1 d gch13 = v 3 v 1 d gch14 = v 4 v 1 3 5 7 m v 1 4 3 m v 3 v 1 . 5 v 0 v 0 v 5 v v v o b v v o w v j o g v s g 2 6 ( p i n 2 6 d d s / m a s k i n p u t ) s g 3 1 ( p i n 3 1 r e c l / j v d i n p u t ) p 3 4 ( p i n 3 4 y o u t ) o u t p u t p e d e s t a l l e v e l r e f e r e n c e s y n c t i p l e v e l r e f e r e n c e s g 3 0 ( p i n 3 0 v i n 1 i n p u t ) 1 0 0 % w h i t e y s i g n a l
