Instrukcja jest OK. Schematy czytelne, opisane niektóre procedury.

2-5. Sync Level Adjustment
n Perform �2-3. +5 V Power Supply Voltage Adjustment� in advance. Measuring equipment: Waveform/vector monitor 1. Supply black burst signal from the signal generator to VIDEO IN connector. 2. Set the waveform/verctor as follows: MODE: WAVEFORM INPUT: CH-A REF: INT 3. Adjust the sync level on the oscilloscope. Measuring point: BLACK BURST OUT1 connector Adjustment point: 1RV201/SG-262 (H-1) Specification: A = 40 ±4 IRE (A = 286 ±30 mV p-p)
2-6. Offset Adjustment
n Perform �2-3. +5 V Power Supply Voltage Adjustment� in advance. Measuring equipment: Oscilloscope 1. Supply black burst signal from the signal generator to VIDEO IN connector. 2. Set the oscilloscope as follows: CH1: DC 20 mV/DIV TIME: 20 µs/DIV TRIG: CH1, LINES 3. Adjust the pedestal DC level on the oscilloscope. Measuring point: BLACK BURST OUT1 connector Adjustment point: 1RV203/SG-262 (J-1) Specification: A = 0 ± 10 mV dc

4. Make sure that each output signal of the BLACK BURST OUT 2 through 6 connectors satisfy the specification.
4. Make sure that each output signal of the BLACK BURST OUT 2 through 6 connectors satisfy the specification. 5. After turning off the power, reset the switch S201 on the SG-262 board to the customer settings.
