Sec. 2.1047 Measurements required: Modulation characteristics.
(a) Voice modulated communication equipment. A curve or equivalent data
showing the frequency response of the audio modulating circuit over a range
of 100 to 5000 Hz shall be submitted. For equipment required to have an
audio low-pass filter, a curve showing the frequency response of the filter,
or of all circuitry installed between the modulation limiter and the
modulated stage shall be submitted.
(b) Equipment which employs modulation limiting. A curve or family of curves
showing the percentage of modulation versus the modulation input voltage
shall be supplied. The information submitted shall be sufficient to show
modulation limiting capability throughout the range of modulating
frequencies and input modulating signal levels employed.
(c) Single sideband and independent sideband radiotelephone transmitters
which employ a device or circuit to limit peak envelope power. A curve
showing the peak envelope power output versus the modulation input voltage
shall be supplied. The modulating signals shall be the same in frequency as
specified in paragraph (c) of Sec. 2.1049 for the occupied bandwidth tests.
(d) Other types of equipment. A curve or equivalent data which shows that
the equipment will meet the modulation requirements of the rules under which
the equipment is to be licensed.
