2.1049(c) Occupied Bandwidth:
Data in the plots show that all sidebands between 50 &
100% for the authorized bandwidth are attenuated by at
least 25dB. From 100 to 250% of the authorize3d band-
width they are attenuated by at least 35dB and beyond
250% 43 log(Po) dB. The plot shows the transmitter
modulated with 15000 Hz(the highest modulation frequen-
cy), adjusted for 50% modulation plus 16 dB. The
spectrum analyzer was set with the unmodulated carrier
at the top of the screen. The test procedure diagram
and occupied bandwidth plots follow.

METHOD OF MEASUREMENT: The procedure used was TIA/EIA STANDARD 603.
The spectrum was scanned from 30 to at least the tenth harmonic of the
fundamental using a HP model 8566B spectrum analyzer and an appro-
priate antenna. Measurements were made at the open field test site of
TIMCO ENGINEERING INC. located at 849 NW SR 45 Newberry, Florida
32669.

2.1055 Frequency stability:
S74.861(e)(4)
------------------------------------------------------------
Temperature and voltage tests were performed to verify that
the frequency remains within the .0050%,(50 ppm)(74.861 e.4)
specification limit.
The test was conducted as follows: The transmitter was
placed in the temperature chamber at 25 degrees C and al-
lowed to stabilize for one hour. The transmitter was keyed
ON for one minute during which four frequency readings were
recorded at 15-second intervals. The worse case number was
taken for temperature plotting. The assigned channel
frequency was considered to be the reference frequency. The
temperature was then reduced to -30 degrees C after which
the transmitter was again allowed to stabilize for one hour.
The transmitter was keyed ON for one minute, and again
frequency readings were noted at 15-second intervals. The
worst-case number was recorded for temperature plotting.
This procedure was repeated in 10-degree increments up to +
50 degrees C.

RESULTS OF MEASUREMENTS: The maximum frequency variation over
the temperature range was -21.37 to

variation over the voltage range was
+0.40 ppm.
