ELECTRICAL CHARACTERISTICS TEST METHOD
ICC1 Circuit current1
Measuring conditions are as listed in supplementary Table.
Measured with a current meter at test point IA.
ICC2 Circuit current2
Measuring conditions are as listed in supplementary Table.
Measured with a current meter at test point IB.
Vomax Output dynamic range
Decrease V1 gradually, and measure the voltage when the
waveform output is distorted. The voltage is called VOL.
Next, increase V1 gradually, and measure the voltage when the
top of waveform output is distorted. The voltage is called VOH.
Voltage Vomax is calculated by the equation below:
Vomax = VOH-VOL

Gv Maximum gain
Input SG1, and read the amplitude output at OUT (24, 28, 31). The
amplitude is called VOUT (24, 28, 31). Maximum gain GV is
calculated by the equation below:
GV=20Log VOUT (dB)
0.7
∆Gv Relative maximum gain
Relative maximum gain DGV is calculated by the equation bellow:
∆GV= VOUT (24)/VOUT (28),
VOUT (28)/VOUT (31),
VOUT (31)/VOUT (24)
VC1 Main contrast control characteristics1
Measuring the amplitude output at OUT (24, 28, 31). The
measured value is called VOUT (24, 28, 31). Main contrast control
characterics VC1 is calculated by the equation bellow:
VC1=20Log VOUT (dB)
0.7
∆VC1 Main contrast control relative characteristics1
Relative characteristics ∆VC1 is calculated by the equation bellow:
∆VC1=VOUT (24)/VOUT (28),
VOUT (28)/VOUT (31),
VOUT (31)/VOUT (24)
Vimax Maximum input
Increase the input signal (SG2) amplitude gradually, starting from
700mVP-P. Measure the amplitude of the input signal when the
output signal starts becoming distorted.
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.
