8
Signal F
0 [V]
Pins 8, 9
Adjust the input signal amplitude so that the output level of
pin 8 is at minimum. Measure the output levels of 1 kHz
spectrum of pin 8 (V8) and pin 9 (V9 ) by a spectrum
analyzer.
Sepa [dB] = 20 og (V9 / V8)
9
Signal H
0 [V]
2.5 [V]
0 [V]
Pins 8, 9
Measure the output levels of 1 kHz spectrum of pin 8 (V8)
and pin 9 (V9) by a spectrum analyzer.
CT [dB] = 20 og (V9 / V8)
10
Signal I
0 [V]
Variable
0 [V]
Pin 4
Raise the voltage of pin 4 from 0 V. Measure the upper limit
voltage (Vmax M [V]) holding the output from pin 8 at 1 kHz.
Reduce the voltage of pin 4 from 2.5 V. Measure the lower
limit voltage (Vmin B (1) [V]) holding the output from pin 8 at
400 Hz.Raise the voltage of pin 4 from 2.5 V. Measure the
upper limit voltage (Vmax B (1) [V]) holding the output from
pin 9 at 1 kHz.
Reduce the voltage of pin 4 from 5 V. Measure the lower limit
voltage (Vmin B (1) [V]) holding the output from pin 9 at
400Hz.
Raise the voltage of pin 4 from 5 V. Measure the upper limit
voltage (Vmax S [V]) holding the output from pin 9 at 400 Hz.
Reduce the voltage of pin 4 from 9 V. Measure the lower limit
voltage (Vmin B (2) [V]) holding the output from pin 9 at 1
kHz.
11
Signal E
Variable
0 [V]
Pin 3
Raise the voltage of pin 3 from 0 V. Measure the upper limit
voltage (Vmax FMono [V]) holding the output from pin 8 to 0
V.
Reduce the voltage of pin 3 from 5 V. Measure the lower limit
voltage (Vmin FMono [V]) holding the output from pin 8 at 1
kHz.
12
Signal A
0 [V]
Variable
Pin 7
Raise the voltage of pin 7 from 0 V. Measure the voltage
(Vmute [V]) when the output from pin 8 or pin 9 changes to 0
V.
13
Signal A
0 [V]
5 [V]
Pins 8, 9, 10
Measure the output levels of the pins (VMute [mVp-p]).
14
No signal
0 [V]
0 / 5 [V]
Pins 8, 9, 10
Switch the pin 7 voltage between 0 V and 5 V. Measure the
DC voltage change of the pins (VOS [V]).
