(4) Adjust A1A14R89 (fig. 1) until DEVIATION (kHz) WATTS meter indicates 40 W.
(5) Adjust signal generator and RF power amplifier for RF power meter reading in a (9)
above. Adjust A1A14R91 (fig. 1) until DEVIATION (kHz) WATTS meter indicates 50 W.
19. DE MOD Signal
a. Performance Check
(1) Connect multimeter cable to EXT ACC jack on TI.
(2) Connect multimeter to model MM-100E multimeter DE MOD jack.
(3) Set RF FREQUENCY MHz switches to 125 500 0 and AM-FM switch to AM.
CAUTION
Do not exceed -30 dBm into antenna input.
(4) Connect measuring receiver to signal generator output (set to minimum).
at modulation of 1 kHz at 60 percent as indicated on the measuring receiver.
(6) Connect signal generator to TI ANTENNA INPUT jack using attenuator
(fixed).
(7) If multimeter does not indicate between 95 and 105 mV ac, perform b below.
b. Adjustments. Adjust A1A13R115 (fig. 5) until multimeter indicates 100 mV ac.
20. MM-100E Multimeter
a.
Performance Check
CAUTION
Do not exceed 300 V into TI multimeter INPUT.
NOTE
The MM-100E multimeter will be referred to as "TI multimeter"
throughout the check.
(1) Position TI multimeter controls as listed in (a) through (d) below:
(a) RANGE switch to .1V.
(b) FUNCTION switch to DC+.
(c) DC ZERO OFFSET control fully ccw (detent).
(d) VOL control fully ccw.
(2) Set MODULATION FREQ Hz switches to 04 000.0.
(3) Connect multimeter to EXT ACC jack on TI. If multimeter does not indicate
zero, perform b (1) below.
