TEST CIRCUIT AND TESTING METHODS
TESTING METHODS
1) POWER SUPPLY CURRENT
· ‘MUTE OFF’ Mode
Measure current ‘A1’ while control, Pin 9, is ‘Lo’ (or open).
· ‘MUTE ON’ Mode
Measure current ‘A1’ while control, Pin 9, is ‘Hi’.
2) ATTENUATION VOLUME
· Attenuation is calculated by the following equation while control, Pin 9, is ‘Hi’:
Pin 1(Pin 7) output AC voltage
ATT = 20Log
3) CAPACITOR PIN CHARGING AND DISCHARGING CURRENT
· Charging Current
Measure outflow current ‘A2’ while control, Pin 9, is ‘Hi’ and the voltage at Pin 13 is V
SS
+ 0.75 V.
· Discharging Current
Measure inflow current ‘A2’ while control, Pin 9, is ‘Lo (or open)’ and the voltage at Pin 13 is V
SS
+ 0.75 V.
4) CONTROL SWITCH VOLTAGE
· ‘MUTE OFF’ Mode
Gradually elevate Pin 9 voltage above V
SS
. When the Attack action (Mute On) is implemented at Pin 1 (Pin 7),
measure the voltage ‘V1’.
· ‘MUTE ON’ Mode
Gradually lower Pin 9 voltage below V
DD
. When the Release action (Mute Off) is implemented at Pin 1 (Pin 7),
measure the voltage ‘V1’.
5) ‘MUTE ON’ OUTPUT DC VOLTAGE
· Measure output voltage at Pin 1 (Pin 7) while control, Pin 9, is ‘Hi’ and there is no input.
6) TOTAL HARMONIC DISTORTION
· Measure the distortion of the Pin 1 (Pin 7) output while control, Pin 9, is ‘Lo’ (or open).
7) SIGNAL VOLTAGE GAIN
· Signal gain is calculated by the following equation while control, Pin 9, is ‘Lo’ (or open).
Pin 1(Pin 7) output AC voltage
Pin 2(Pin 6) input AC voltage
8) INNER ATTENUATION RESISTANCE
· Using a multimeter, measure the resistance between Pin 1 (Pin 7) and Pin 2 (Pin 6) while the power supply is
off.
9) MAXIMUM INPUT SIGNAL VOLTAGE
· While control, Pin 9, is ‘Lo’ (or open), gradually elevate Pin 2 (Pin 6) voltage above 0 V
P-P
. When the distortion
becomes 0.01% at the output of Pin 1 (Pin 7), measure the AC voltage.
