a. Performance Check
(1) Connect equipment as shown in figure 4.
(2) Press TI pushbuttons as listed in (a) through (g) below:
(a)
Preset.
(b)
Frequency, 1, [GHz].
(c)
Amplitude, 0, [dBm].

MENUS AM, [AM Depth], 3, 0, [%].
(e)
[AM Rate], 1, 0, [kHz].
(f)
[AM Off/On] to on.
(g)
RF On/Off to on.
(3) Set measuring receiver to measure AM with 15 kHz low-pass filter and a 300 Hz
high-pass filter.
(4) Using measuring receiver, measure AM percent of modulation. Measuring
receiver will indicate within limits specified in first row of table 10.
(5) Repeat technique of (2) (d) and (4) above using the AM Depth and measuring
receiver indications listed in table 10. Measuring receiver will indicate within limits
