ON
94H
—
(1) Input waveform 1 to pin 33 (B-Yin) , and measure VNBD,
that pin 36 (B-Yout) is saturated input level.
(2) Measure VNRD of R-Y input in the same way as VNBD.
H2
1HDL Dynamic Range
Delay
↑
8CH
—
(1) Input waveform 1 to pin 33 (B-Yin), and measure VPBD, that pin 36 (B-Yout) is saturated input level.
(2) Measure VPRD of R-Y input in the same way as VPBD.
H3
1HDL Dynamic
Range,Direct + Delay
↑
A4H
—
(1) Input waveform 1 to pin 33 (B-Yin), and measure VSBD, that pin 36 (B-Yout) is saturated input level.
(2) Measure VNRD of R-Y input in the same way as VSBD.
H4
Frequency
Characteristic, Direct
↑
94H
—
(1) In the same measuring as H1, set waveform 1 to 0.3 Vp-p and f = 100 kHz. Measure VB100, that is pin 36 (B-Yout) level.
And set waveform 1 to f = 700 kHz. Measure VB700, that is pin 36 (B-Yout) level.
GHB1 = 20 og (VB700 / VB100)
(2) Measure GHR1 of R-Y out in the same way as GHB1.
H5
Frequency
Characteristic, Delay
↑
8CH
—
(1) In the same measuring as H1, set waveform 1 to 0.3 Vp-p and f = 100 kHz. Measure VB100, that is pin 36 (B-Yout) level.
And set waveform 1 to f = 700 kHz. Measure VB700, that is pin 36 (B-Yout) level.
GHB2 = 20 og (VB700 / VB100)
(2) Measure GHR2 of R-Y out in the same way as GHB2.
H6
AC Gain Direct
↑
94H
—
(1) In the same measuring as H1, set waveform 1 to 0.7 Vp-p. Measure VByt1, that is pin 36 (B-Yout) level.
GBY1 = 20 og (VByt1 / 0.7)
(2) Measure GRY1 of R-Y out in the same way as GBY1.
H7
AC Gain Delay
↑
8CH
—
(1) In the same measuring as H1, set waveform 1 to 0.7 Vp-p. Measure VByt2, that is pin 36 (B-Yout) level.
GBY2 = 20 og (VByt2 / 0.7)
(2) Measure GRY2 of R-Y out in the same way as GBY2.
