8.2 Peak Transmit Power, §15.319(c), and Power Spectral Density,
§15.319(d)
The EUT was directly connected to the spectrum analyzer through its antenna output port. The handset
was configured to operate continuously on predetermined channels. The peak transmit power and the
power spectral density were measured according to section 6.1.2 of ANSI C63.17: 1998. The peak transmit
power was measured with a resolution bandwidth of 1 MHz and a video bandwidth of 3 MHz. The peak
transmit power was also verified using a peak power meter. The measurements were performed on two
channels, one near the top of the spectrum and one near the bottom per 47 CFR 15.31(m).
Power spectral density measurements were made with a resolution bandwidth of 3 kHz and a video
bandwidth of 10 kHz. The highest peak of any 3 kHz span was recorded.
8.3
Emission Bandwidth
The emission bandwidth was determined according to section 6.1.3 of ANSI C63.17: 1998.
8.4
Spurious Emissions, §15.323 (d)
The EUT was directly connected to the spectrum analyzer through the antenna output port. The handset
was configured to operate continuously on predetermined channels. Emissions were measured from 30
MHz to 19.3 GHz. All emissions detected within 20 dB of the limit were reported. The spurious emissions
were measured according to section 6.1.6 of ANSI C63.17: 1998.
8.5
Carrier Frequency Stability, §15.323 (f)
The EUT was placed inside a temperature chamber and directly connected to a spectrum analyzer through
the antenna port. The handset was configured to operate as needed on predetermined channels. The EUT
was placed inside the chamber and brought to a temperature of 20
E
C for one hour in order to stabilized the
temperature of the EUT. The frequency was recorded and used as the reference for the measurements at
the two extreme temperatures.
