Set V31 = 1.6V.
Then measure the amplitude of the PRG
section using the output waveform at TP13.
Frequency response from (R IN), (G IN) and (B
IN) to TP15, TP16 and TP17 (frequency which
goes to –3dB with respect to 100kHz)
Frequency response from (R IN), (G IN) and
(B IN) to the sample-and-hold circuit input
(frequency which goes to –3dB with respect to
100kHz)
Input SG6 to (R IN), (G IN) and (B IN).
Then adjust V45 so that the output amplitude
(black to white) at TP16 is 3V.
Measure the slew rate from the 10 to 90% rise
and fall time of TP15, TP16 and TP17.
Set SW41
(variable amplitude) to (R IN), (G IN) and (B
IN).
Then label the amplitude of the 1st, 5th and
10th steps as b1, b5 and b10, respectively,
using the non-inverted output waveform at
TP15, TP16 and TP17.
The input dynamic range is defined as the
minimum value for the input amplitude (black
to white) at which b1/b5 < 0.8 or
b10/b5 < 0.8.
Set V45 = V
and (SH3).
Then measure the droop rate at TP15, TP16
and TP17.
Next, input SG7 to (SH4).
Then measure the droop rate of TP15, TP16
and TP17.
