1. Extend the VDA-49 board with a extension board.Measuring equipment: Oscilloscope
2. Write the customer settings of the switches (S101,
S201, and S301) on the VDA-49 board down in1. Generate following signal from the signal generator.
following table.Output: 270 M bits/sec. (4:2:2 component signal)
3. Set their switches as follows:2. Set the oscilloscope as follows:
CH1:AC 200 mV/DIV
Ref. No. (Address)Setting at adj.Customer Setting
TIME: 2 ns/DIV
S101 (A-1)No. 1: OFF
TRIG:CH1
No. 2: ON
No. 3: OFFCH1 adjustment
No. 4: ON3. Connect the signal generator to the CH1 SDI IN connector.
4. Connect the oscilloscope to the CH1 SDI OUT 1 connector.
S201 (A-2)No. 1: OFF
5. Adjust the output level on the oscilloscope.
No. 2: ON
Adjustment point:1RV101/VDA-49 (E-1)
No. 3: OFF
Specification: ?20 mV p-p800
No. 4: ON
S301 (A-2)No. 1: OFFCH2 adjustment
No. 2: ON6. Connect the signal generator to the CH2 SDI IN connector.
No. 3: OFF7. Connect the oscilloscope to the CH2 SDI OUT 1
No. 4: ONconnector.
8. Adjust the output level on the oscilloscope.
4. Turn on the power of equipment (the signal generator,Adjustment point:1RV201/VDA-49 (E-1)
oscilloscope, and interface unit PFV-L1 or PFV-L10),Specification: ?20 mV p-p800
and warm up them for about ten minutes.
CH3 adjustment
9. Connect the signal generator to the CH3 SDI IN
connector.
10. Connect the oscilloscope to the CH3 SDI OUT 1
connector.
11. Adjust the output level on the oscilloscope.
Adjustment point:1RV301/VDA-49 (E-2)
Specification: ?20 mV p-p800
12. After turning off the power, reset the switches (S101, S201,
and S301) on the VDA-49 board to the customer settings.
