delay mode (A probe 10:1 should be used unless otherwise
specified.)

3)

Frequency counter

4)

Pattern generator

5)

Digital voltmeter

6)

Audio generator

7)

Audio level meter

8)

Audio distortion meter

9)

10) Alignment tapes

KRV-51N2

Part No.: 8-192-605-32

2-1-2. Equipment Connection

Unless otherwise specified, connect and adjust the measuring
instruments as shown in the following diagram.

Fig. 6-2-1.

2-1-3. Input Signal Check

Video signal produced by a pattern generator is used as an adjustment
signal to perform electrical alignment for this unit. This video signal
must satisfy the specification.

Unless otherwise specified, place the switches and controls of this
unit in the following positions:

INPUT SELECT    switch ............................. LINE or LINE 1

 (Remote commander)

Connect an oscilloscope to the Video Input terminal. Check that the
synchronizing signal of the Y signal has an amplitude of
approximately 0.7V and that the burst signal has an amplitude of
approximately 0.3V and its waveform is flat. And check that the
level ratio of burst signal to “red” signal is 0.30 : 0.66. The video
signal (color bar) used for electrical aligning this unit is shown in
Fig. 6-2-2.
