Detailed Explanation of Measurement Method (1) DEMOD LPF frequency characteristics measurement Using the CXA1207A as a modulator, the configuration for SG41 is shown below.

DEMOD OUT
First, without inputting SG54, adjust VCAR so that the Y RF OUT (Pin 43) output frequency of the CXA1207A is 5MHz. 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. fo (MHz)–5 (MHz) 500 (mV)
GMOD =
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)

(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 V1, V2, V3, and V4 of output P63 (Pin 63 C OUT) and calculate the gain difference between channels using the following equations: V2 V1 V3 V1 V4 V1

Precautions Concerning Measurements (Refer to Electrical Characteristics Measurement Circuit). 1. Start measurements after making the following adjustments. 1) Recording level (video AGC) adjustment With the SW conditions (SW30: on) and the mode conditions: B the same as for measurement Nos. 11 to 13, adjust V31 so that the P34 (Pin 34 Y OUT) output is 500mVp-p when signal b (100% white, 500mVp-p Y signal) is input from SG30. 2) CAR adjustment (normal) With the SW conditions at the initial settings and the mode conditions: A, adjust V44 so that the frequency of the P39 (Pin 39 Y RF OUT) output is 4.2MHz. 3) Chroma emphasis adjustment With the SW conditions (SW24-1, SW24-2, SW53: on), and the mode conditions: P the same as for measurement Nos. 84 to 89, adjust V1 so that the signal level for the chroma interval of the P8 (Pin 8 REC C OUT) output is at a minimum when signal l is input from SG24 and signal i is input from SG53. (chroma interval 3.58MHz/99.3mVp-p) 2. Although no input conditions are indicated for C measurement Nos. 80 to 126, signal l is input from SG24. Unless otherwise specified in the input conditions, the frequency for SG24 is 15.734kHz. 3. Note that in regards to the measurements shown below, the characteristics change depending on the floating capacitance. 1) White/dark clipping level 2) Pre-emphasis characteristics 3) REC APC pull-in range 4. When taking measurements, use metal film resistors with an allowable deviation of 1% for R1, R2, R3, and R5, and use temperature compensation CH types for C1, C2, C3, and C4.

Description of Operation 1. 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).

2. 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).

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.

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.

The Y FM modulation carrier frequency is adjusted by applying an external DC bias to CARR CONT (Pin 44). When carrier adjustment is performed, gm1 and gm2, the deviation/smear gain, change in proportion to IXCAR at the same time. This results in the FM modulator sensitivity being roughly adjusted for the Dev IN/Sme IN signal level. Fine adjustment of the deviation frequency is accomplished by the DC bias applied to DEV CONT (Pin 43).

De-emphasized playback Y signal is input to the comb block. By passing the differential component of the nH signal and the (n+1) H signal through the limiter, the cross talk component, which is line noncorrelation, is extracted. Cross talk cancellation is accomplished by subtracting this cross talk component from the nH playback Y signal. In addition, by switching modes CFL1 and CFL2, the comb depth characteristics of PBY cross talk cancellation can be changed. The standard characteristics of comb depth for low frequency (approximately 1MHz) and insignificant input level (MAIN EMPH TC (Pin 3) 7.9mVp-p = –30dB) input are shown below.
