Step 4. CCD azimuth rough adjustment

(1) Input the command m110 from the PC keyboard and

then press the Enter key.

(2) Loosen the P side azimuth fixing screw about a half

turn using hex wrench driver (across 2.5 mm).

(3) Rotate and adjust the CCD azimuth adjustment screws

so that the output waveform of the oscilloscope meets

the following specification.

Specification : A portion (second) of the output

waveform should be parallel.

(4) After the adjustment has been completed, tighten the

CCD azimuth fixing screw loosened at the procedure

(2) above.

Step 5. CCD focus fine adjustment

(1) Connect the filter tool between the TP1 on the RD-35

board and oscilloscope CH1 as shown in the figure.

(2) Input the command m100 from the PC keyboard and

then press the Enter key.

(3) Rotate and adjust the second and third CCD adjust-

ment screws from the mechanical deck chassis so that

the ◊ part (eye patterns) of the output waveform (TP1)

of the oscilloscope CH1 becomes maximum.

(4) Tighten the loosened two hexagon cap screws at the

bottom of the optics block in “procedure (3) of Step

2”, and check that the ◊ portions (eye patterns) do not

change.
