(d) Adjust OUTPUT LEVEL to 0 dB.
(e) RF OUTPUT to on.
(f) MTR FM to on.
(g) FM DEVIATION MHz .1 on.
(3) Set the audio analyzer to produce a 100 kHz, 0.01 V LEVEL STEP size, 1.414 V
output with 600 Ω output impedance, then select special function 17.
(4) Set measuring receiver and local oscillator to measure 15 GHz, then select FM
measurement and 300 Hz HP FILTER, 3 kHz LP FILTER, and +PEAK detector.
(5) Adjust A1A6R35 (fig. 15) for an indication of 100.0 1 kHz FM deviation on the
measuring receiver (R).
(6) Adjust A1A6R70 (fig. 15) until TI meter indicates 100 kHz FM deviation (needle
at full scale) (R).
(7) Reduce all outputs to minimum.
(8) Replace TI top cover.

a. Performance Check
(1) Connect digital multimeter to A3A1TP1 and chassis (fig. 16). If digital
multimeter does not indicate between +21.98 and +22.02 V dc, perform b (1) below.
