| D.L, | The D.L. of M51395AP is applied commonly. |
A pot core and a screw core are manufactured by Taivo Yuden, Japan.
Adjustment of electrical characteristic for PAL/SECAM dual system circuit M51395AP/M51397AP.
Adjustment is achieved as following sequence.
- 1. Bell filter transformer "T1" (M51397AP) Apply SECAM color signal to the input. Adjust bell filter transformer "T1" to make the color signal envelope at test point "TP2" into flat.
- Ident discriminator coil "L1" (M51397AP) Adjust ident discriminator coil "L1" to give maximum ident filter voltage value at test point "TP1".
- 3. Discriminator (Demodulator) coil "T3/T4" (M51397AP) Adjust discriminator coil "T3/T4" to make the voltage of no color signal equal to the clamp voltage (~7.2V) at pins 18 and 22.
- 4.4.433619MHz free run frequency (M51395AP) Apply PAL B/W signal (no burst) to input, and connect 0.01μF between pin 1 and GND.
Connect high input impedance frequency counter at pin 17.
Adjust the trimmer capicitok "Ct" to frequency 4.433619MHz.
5. Burst cleaning coil "L10" (M51395AP)
Apply PAL color signal to input.
Adjust burst cleaning coil "L10" to give minimum chroma output signal value at pin 24.
Delay line transformer "T2", chroma difference signal control "VR3" (M51395AP)
Adjust delay line transformer "T2" and chroma difference signal control "VR3" to correct demodulated ratios at pins 18, 20 and 22. If demodulated ratios are not correct, readjust burst cleaning coil "L10".
