(30) TI will indicate between 10.98 and 12.37 kHz.
(31) Adjust synthesized signal generator FM Rate to 15.0 kHz and FM Deviation for
a 36.0 kHz deviation indication on measuring receiver.
(32) Press LOW-PASS (kHz) 15 and RANGE 100 pushbuttons. TI will indicate
between 23.9 and 27.0 kHz.
(33) Adjust synthesized signal generator FM Rate to 120.0 kHz and FM Deviation for
a 290.0 kHz deviation indication on measuring receiver.
(34) Press LOW-PASS (kHz) 120 and RANGE 300 pushbuttons. Record TI
indication.
(35) Set synthesized signal generator FM to Off. Subtract TI indication from
indication recorded in (34) above. Difference will be between 191 and 216 kHz.
(36) Set synthesized signal generator FM to On, and set FM Rate to 200.0 kHz.
(37) Set synthesized signal generator FM Rate to 200.0 kHz, and FM Deviation for a
160.3 kHz deviation indication on measuring receiver.
(38) Press LOW-PASS 200 kHz pushbutton. Record TI indication.
(39) Set synthesized signal generator FM to Off. Record TI indication.
(40) Subtract value recorded in (39) above from value recorded in (38) above. If
difference is not between 96.12 and 117.5 kHz, perform b below.
plus value recorded in (39) above (R).
13. Power Supply
NOTE
Do not perform power supply check if all other parameters are
within tolerance.
a. Performance Check
(1) Connect multimeter to +15 V TP (figure 4) and chassis ground, using two leads.
If multimeter does not indicate between +14.95 and +15.05 V dc, perform b below.
