(10) Readjust AMPLITUDE COARSE and FINE controls for an indication of 40 V
on OUTPUT LEVEL meter. Record true rms voltmeter indication.
(11) Adjust frequency dial and RANGE switch through frequency range of 5 to 500
kHz, maintains 40 on OUTPUT LEVEL meter.
(12) True rms voltmeter indication will remain between -1 and +1 dB of value
recorded in (10) above.
b. Adjustments. No adjustments can be made.
a. Performance Check
(1) Connect audio analyzer to UNBAL. OUTPUT connector using voltage divider.
(2) Set MOD BAL. - BAL. - UNBAL. switch to UNBAL.
(3) Set RANGE switch to X100, and frequency dial to 100.
(4) Adjust AMPLITUDE COARSE and FINE controls for a 6 V ac indication on
audio analyzer meter.
(5) Audio analyzer will indicate less than 1.0 percent at 10 kHz.
(6) Adjust AMPLITUDE COARSE and FINE controls fully ccw.
(7) Connect audio analyzer to BAL. OUTPUT connector using voltage divider.
(8) Set MOD BAL. - BAL. - UNBAL. to BAL.
(9) Set RANGE switch to X100, and frequency dial to 100.
(10) Adjust AMPLITUDE COARSE and FINE controls for a 40 V ac indication on
analyzer meter.
(11) Audio analyzer will indicate less than 3.0 percent at 10 kHz.
b. Adjustments. No adjustments can be made.
a. Performance Check
NOTE
Do not perform power supply check if all other parameters are
within tolerance.
(1) Connect multimeter between pin 8 of V7 (fig. 4), and ground. Multimeter will
indicate between 230.0 and 250.0 V dc, if not perform b below. Record indication.
(2) Vary autotransformer output between 105 and 125 V ac.
indicate within 1.0 V of value recorded in (1) above.
