Use VCARO for the VCAR voltage. Next, apply VCARO + 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)–5 (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 : GC1 = 20log [GMOD (MHz/mV) × GDEMOD1 (mV/MHz)] Hi-8 mode compensation value : GC2 = 20log [GMOD (MHz/mV) × GDEMOD2 (mV/MHz)] Next, in order to set the SG41 carrier frequency, adjust VCAR 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 GLPF10 and for Hi-8 mode GLPF20. Using these measured values and compensation values, the low frequency gain for DEMOD LPF is determined using the following equations: Standard mode : GLPF11 = GLPF10 - GC1 (dB) Hi-8 mode : GLPF21 = GLPF20 - GC2 (dB) —28— CXA1810AQ/AR (2) DDS measurement When a pulse with the following timing is input, the output from P34 (Pin 34 Y OUT) becomes as shown below; measures each DC difference. 357mV SG30 (Pin 30 VIN1 input) 100% white Y signal 143mV 3V 1.5V SG26 (Pin 26 DDS/MASK input) 0V 5V SG31 (Pin 31 RECL/JVD input) 0V VVOB Pedestal level reference P34 (Pin 34 Y OUT) output Sync tip level reference VVOW VJOGV (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.

Signal path during composite recording Composite signals input from VIN1 (Pin 30) and VIN2 (Pin 28) are selected by mode INSEL, passed through the VIDEO AGC, and Y/C separated by the comb filter. The Y signal is output to Y COMB OUT (Pin 14). Next, level adjustment is performed externally and then the signal is input to EMPH IN (Pin 5), after which hard clipping, emphasis, white/dark clipping, and FM modulation are performed and then the signal is output from Y RF OUT (Pin 39). In addition, the Y OUT (Pin 34) signal is input to Y IN (Pin 32), and then the monitor signal is output from VIDEO OUT (Pin 36). On the other hand, Y/C-separated C signal passes through the BPF and then along with being output to C OUT (Pin 63), the signal is also passed through ACC, chroma emphasis, and burst emphasis, low frequency converted, is passed though a LPF and then output from REC C OUT (Pin 8).

Signal path during playback (W CCD) The playback Y RF signal, after having passed though RF AGC and a soft limiter, is input to Y RF IN (Pin 41). After FM demodulation, the signal passes through the LPF and is then output from DEMOD OUT (Pin 7). After the waveform is formed and the level is adjusted by an external LPF, EQ, and peaking amplifier, the signal is input to DE EMPH IN (Pin 10), after which clipping compensation, de-emphasis and HHS cancellation are performed. Next, cross talk cancellation is performed by a comb filter and then the signal is output from Y COMB OUT (Pin 14). After the waveform is formed and the level is adjusted by an external EQ (LPF) and peaking amplifier, the signal is input to EMPH IN (Pin 5), where it passes through a noise canceler and is then output from Y OUT (Pin 34). On the other hand, the playback RF signal, after passing through AFM and ATF TRAP, is input to PBC IN (Pin 45), after which the low-frequency C signal is separated by the PBC LPF. Next, the playback C signal, which has undergone level control by the ACC and frequency conversion by PB CONV and PBC BPF, is subjected to cross talk cancellation by the comb filter, and then after undergoing burst de-emphasis and chroma de-emphasis, the signal is output from C OUT (Pin 63). By inputting the playback Y signal (Y OUT (Pin 34) output) to Y IN (Pin 32) and the playback C signal (C OUT (Pin 63) output) to C IN (Pin 64), the Y/C mixed signal is output from VIDEO OUT (Pin 36). CXA1810AQ/AR CXA1810AQ/AR 3. REC LEVEL adjustment The video signal input to VIN1 (Pin 30) and VIN2 (Pin 28) is selected by mode INSEL, and when mode video AGC is High, the signal is passed through SYNC AGC and PEAK AGC and then is output from Y OUT (Pin 34). The output level can be adjusted by applying an external DC bias (1.3 to 2.6V [Vcc = 4.75V]) to RECL/JVD (Pin 31). In the case of 100% white , 500mVp-p input, the following are the standard characteristics. Y OUT (Pin 34) output level (mVp-p) 600 500 400 1.0 1.5 2.0 2.5 3.0 REC L/JVD (Pin 31) control DC (V) 4.

The threshold value for raw signal and VOB/masking is 1.1V, and the threshold value for VOB/masking and VOW is 2.0V (when Vcc = 4.75V). In addition, the VOW replacement signal level can be varied within the range of the DC level (2.3V to 3.0V) for this pin; those standard characteristics are shown below.

Y/C separation adjustment Mode: REC, 5 SHP THRU = High Input signal : color bar 500mVp-p (Pin 30 V IN1) Adjustment method : Adjust RV110 (YC.SEP) → RV103 (COMB.ADJ) → RV110 (YC.SEP) in turn so that 3. 4. 5. 6. 7. the residual chroma component at Y COMB OUT (Pin 14) is minimum. Emphasis input Y level adjustment Mode : REC Input signal : color bar 500mVp-p (Pin 30 V IN1) Adjustment method : Adjust RV112 (EMPH.Y.LEV) so that the Y signal level at EMPH IN (Pin 5) is 500mVp-p. Y-FM carrier deviation adjustment Mode : REC, 22 E = Low (standard mode); E = High (Hi-8 mode) Input signal : 100% white, 500mVp-p (Pin 30 V IN1) Adjustment method : While monitoring the Y RF OUT (Pin 39) signal with a spectrum analyzer, adjust RV108 (CARR) so that the H SYNC spectrum (carrier) is 4.2MHz in standard mode and 5.7MHz in Hi-8 mode, and adjust RV107 (DEV) so that the 100% white Y level spectrum is 5.4MHz in standard mode and 7.7MHz in Hi-8 mode. Chroma emphasis fo adjustment Mode : REC, 2 TEST1 = High Input signal : color bar 500mVp-p (Pin 30 V IN1) Adjustment method : Adjust RV102 (CEMPH) so that the level of the flat portion of the chroma signal after burst emphasis output to REC C OUT (Pin 8) is minimum. PB Y level 1 adjustment Mode : PB, 27 W CCD = Low (when using one CCD delay line) W CCD = High (when using two CCD delay lines) Input signals : PB Y RF 200mVp-p (Pin 41 Y RF IN) Adjustment method : Adjust RV111 (PB.Y.LEV1) so that (when using one CCD delay line) DL IN 1 (Pin 23) or (when using two CCD delay lines) DL IN 2 (Pin 17) is 500mVp-p respectively. PB Y level 2 adjustment Mode : PB Input signal : PB Y RF 200mVp-p (Pin 41 Y RF IN) Adjustment method : When VIDEO OUT (Pin 36) is terminated with 75Ω, adjust RV113 (PB.Y.LEV2) so that the output is 1Vp-p.
