20 ASSIGNABLE OUT-3
Insert the appropriate phone plugs into the ASSIGNABLE OUT-3
terminal. Check the output wave form and the output level of each
output by using an oscilloscope, an AC voltmeter (with JIS-C filter)
and a distortion factor meter.
ASSIGNABLE OUT-3: 1 kHz +/- 1 Hz, sine wave, less than 0.5%
distortion
0 +/- 3 dBm (10 k ohm load)
ASSIGNABLE OUT-4: less than -70 dBm (10 k ohm load)
While sounding, the LCD shows as below.
RESULT OF THE TEST
No display
END OF THE TEST
After pressing the [ENC5] STOP, the test will be finished.
21 ASSIGNABLE OUT-4
