8 Select the item "1. SC FREQUENCY" with the ARROW
key and press the ENTER key.
(1) Subcarrier Frequency Adjustment for INT mode
Test Point: TD4 (SC VCXO)
8 Connect the Frequency Counter to TD4 as shown in Fig.
4-1-2.
8 Adjust the data with the ARROW key so that the
Subcarrier Frequency becomes 17.734 47 MHz ± 40 Hz.
8 Press the ENTER key for the next adjustment.
(2) Subcarrier Frequency Adjustment for LL mode
Test Point: TD4 (SC VCXO)
8 Connect the Frequency Counter to TD4 as shown in Fig.
4-1-2.
8 Adjust the data with the ARROW key so that the
Subcarrier Frequency becomes 17.734 47 MHz ± 40 Hz.
8 Press the ENTER key for the next adjustment.
(3) Line Lock Phase Adjustment
Test Point: Video Output Connector
AC Live Waveform
8 Connect the CH1 of the Oscilloscope to the Video Output
Connector.
