GV Maximum Gain

Input SG1, and read the amplitude output at OUT (29, 32, 35). The amplitude is called VOUT (29, 32, 35). Maximum

gain GV is calculated by the equation below:

VOUT

GV = 20log 0.7 (dB)

∆GV Relative Maximum Gain

Relative maximum gain ∆GV is calculated by the equation below:

∆GV = VOUT (29) / VOUT (32),

VOUT (32) / VOUT (35),

VOUT (35) / VOUT (29)

VC1 Main Contrast Control Characteristics1

Measuring the amplitude output at OUT (29, 32, 35). The measured value is called VOUT (29, 32, 35). Main contrast

control characteristics VC1 is calculated by the equation below:

VOUT

VC1 = 20log 0.7 (dB)

∆VC1 Main Contrast Control Relative Characteristics1

Relative characteristics ∆VC1 is calculated by the equation below:

∆VC1 = VOUT (29) / VOUT (32),

VOUT (32) / VOUT (35),

VOUT (35) / VOUT (29)

VC2 Main Contrast Control Characteristics2

Measuring condition and procedure are the same as described in VC1.

∆VC2 Main Contrast Control Relative Characteristics2

Measuring condition and procedure are the same as described in ∆VC1.

VC3 Main Contrast Control Characteristics3

Measuring the amplitude output at OUT (29, 32, 35).

The measured value is called VOUT (29, 32, 35).

∆VC3 Main Contrast Control Relative Characteristics3

Measuring condition and procedure are the same as described in ∆VC1.
