ADJUSTMENT PROCEDURE

1. Test Equipments Required

The following Test Equipments are required for adjust-

ment of the Digital Video Multiplexer WJ-FS28.

Underscanned Colour Video Monitor

Vectorscope

Waveform Monitor

PAL Signal Generator

Colour Bar Signal

Ramp Signal (with and without Carrier)

Composite Sync Signal (300 mV Negative Polarity)

Sweep Signal or Multi Burst Signal (more than 10MHz)

Oscilloscope

Frequency Counter

Digital Voltmeter

PAL Black and White Camera

2. Disassembling Procedure for the

Adjustment

Referring to Fig. 2-1, remove six screws that secure the

Upper Cover and remove the Upper Cover.

Fig. 2-1

Remove six screws.

3. Connection and Setting up for

Adjustment

3.1. Connection

Fig. 3-1 shows the connecting diagram for adjustment of

the WJ-FS28.

Fig 3-1

Connect the Underscanned Colour Video Monitor through

the Vectorscope and Waveform Monitor to the Recording

Output Jack on the Rear Panel of the WJ-FS28.

Terminate the input terminal of the Underscanned Colour

Video Monitor with 75

Ω

Connect the Signal Generator to the Camera Input

Connectors 1, 2 and 3 on the Rear Panel of the WJ-FS28.

Connect the prove of the Digital Voltmeter, Oscilloscope

or Frequency Counter at the desired Test Point in each

adjustment step.

3.2. Setting Up

This adjustment should be done after 30 minutes warm up

of the WJ-FS28.

Setting of the Switches for adjustment are as follows:

<Front Panel>

VTR/Camera Selection Switch ...............................Camera

Microphone Level Controls ...................Mechanical Center

<Main Board>

SW901 (Picture Stability)...............................................ON

SW501 (Microphone 1)..................................................0

SW502 (Microphone 2)..................................................0

SW503 (Microphone 3)..................................................0

SW504 (Microphone 4)..................................................0

Turn the Power Switch on while pressing the Cursor ( )

and SELECT (–) buttons simultaneously, ring the buzzer

for one second and enter the Test Mode.

The adjustments should be done with this condition,

unless otherwise specified.

Turn the Power Switch off to quit from the Test Mode.
