13. Amplitude Modulation
a. Performance Check
(1) Connect TI RF Out to measuring receiver RF INPUT.
(2) Set measuring receiver to measure frequency modulation at 10 MHz with PEAK
+-/2 detector.
(3) Press TI keys as listed in (a) through (f) below.
(a)
Preset.
(b)
RF On/Off to Off.
(c)
AMPD, -, 1, 0, and dBm.

(e)
RF On/Off to On.
(f)
AM, AM RATE, 4, 0, 0, Hz, AM DEPTH, 3, 0, % and AM Off/On to On.
(4) Verify that the measuring receiver indication is <10 kHz.
(5) Set measuring receiver to acquire frequency then measure amplitude
modulation, with PEAK +-/2.
(6) Verify that the measuring receiver indicates within limits listed in table 11.
(7) Repeat technique of (3), (5) and (6) above for remaining rows in table 11.
