BUS CONTROLLED 3-CHANNEL VIDEO PREAMP FOR CRT DISPLAY MONITOR

VC3 Main contrast control characteristics3

Measuring the amplitude output at OUT (24, 28, 31).

The measured value is called VOUT (24, 28, 31).

ABL1 ABL control characteristics1

Measure the amplitude output at OUT (24,28,31). The measured

value is called VOUT (24,28,31), and is treated as ABL1.

∆VC3 Main contrast control relative characteristics3

Measuring condition and procedure are the same as described in

∆VC1.

VSC1 Sub contrast control characteristics1

Measure the amplitude output at OUT (24,28,31). The measured

value is called VOUT (24, 28, 31). Sub contrast control

characteristics VSC1 is calculated by the equation below:

VSC1=20Log VOUT (dB)

0.7

∆VSC1 Sub contrast control relative characteristics1

Relative characteristics ∆VSC1 is calculated by the equation below:

∆VSC1=VOUT (24)/VOUT (28),

VOUT (28)/VOUT (31),

VOUT (31)/VOUT (24).

VSC2 Sub contrast control characteristics2

Measuring condition and procedure are the same as described in

VSC1.

∆VSC2 Sub contrast control relative characteristics2

Measuring condition and procedure are the same as described in

∆VSC1.

VSC3 Sub contrast control characteristics3

Measuring the amplitude output at OUT (24,28,31).

The measured value is called VOUT (24, 28, 31).

∆VSC3 Sub contrast control relative characteristics3

Measuring condition and procedure are the same as described in

∆VSC1.

VMSC Main/sub contrast control characteristics

Measure the amplitude output at OUT (24, 28, 31). The measured

value is called VOUT (24, 28, 31). Main/Sub contrast control

characteristics VMSC is calculated by the equation below:

VMSC =20Log VOUT (dB)

0.7

∆VMSC Main/sub contrast control relative characteristics

Relative characteristics ∆VMSC is calculated by the equation

below:

∆VMSC = VOUT (24)/VOUT (28),

VOUT (28)/VOUT (31),

VOUT (31)/VOUT (24)

∆ABL1 ABL control relative characteristics1

Relative characteristics ∆ABL1 is calculated by the equation below:

∆ABL1= VOUT (24)/VOUT (28),

VOUT (28)/VOUT (31),

VOUT (31)/VOUT (24)

ABL2 ABL control characteristics2

Measuring condition and procedure are the same as described in

ABL1.

∆ABL2 ABL control relative characteristics2

Measuring condition and procedure are the same as described in

∆ABL1.

VB1 Brightness control characteristics1

Measure the DC voltage at OUT (24, 28, 31) with a voltmeter. The

measured value is called VOUT (24, 28, 31), and is treated as V B1.

∆VB1 Brightness control relative characteristics1

Relative characteristics ∆VB1 is calculated by the difference in the

output between the channels.

∆VB1= VOUT (24)-VOUT (28),

VOUT (28)-VOUT (31),

VOUT (31)-VOUT (24)

VB2 Brightness control characteristics2

Measuring condition and procedure are the same as described in

VB1.

∆VB2 Brightness control relative characteristics2

Measuring condition and procedure are the same as described in

∆VB1.

VB3 Brightness control characteristics3

Measuring condition and procedure are the same as described in

VB1.

∆VB3 Brightness control relative characteristics3

Measuring condition and procedure are the same as described in

∆VB1.
