Methods of Measurement of the Electromagnetic and Operational Compatibility of UPCS Devices
Annex A
(informative)
47CFR15, Subpart D—Rules and test cases for UPCS devices
47CFR15, Subpart D—Unlicensed PCS Devices, as of December 29 2004 ANSI test
Scope 15.301
This subpart sets out the regulations for unlicensed personal
communications services (PCS) devices operating in the
1910–1930 MHz frequency band.
Information
Definition 15.303
Emission
bandwidth
15.303(c)
emission bandwidth: For purposes of this subpart, the emission
bandwidth shall be determined by measuring the width of the signal
between two points, one below the carrier center frequency and one above
the carrier center frequency, that are 26 dB down relative to the maximum
level of the modulated carrier. Compliance with the emissions limits is
based on the use of measurement instrumentation employing a peak
detector function with an instrument resolutions bandwidth approximately
equal to 1.0 percent of the emission bandwidth of the EUT under
measurement.
6.1.3
Peak transmit
power
15.303(f)
peak transmit power: The peak power output as measured over an
interval of time equal to the frame rate or transmission burst of the EUT
under all conditions of modulation. Usually this parameter is measured as
a conducted emission by direct connection of a calibrated test instrument
to the equipment under test. If the EUT cannot be connected directly,
alternative techniques acceptable to the Commission may be used.
6.1.2
PCS devices 15.303(g)
personal communications service (PCS) devices [unlicensed]:
Intentional radiators operating in the frequency band 1920–1930 MHz
that provide a wide array of mobile and ancillary fixed communication
services to individuals and businesses.
Definition
Spectrum window 15.303(h)
spectrum window: An amount of spectrum equal to the intended
emission bandwidth in which operation is desired.
Definition
Thermal noise
power
15.303(j)
thermal noise power: The noise power in watts defined by the formula
N = kTB, where N is the noise power in watts, k is Boltzmann's constant,
T is the absolute temperature in degrees Kelvin (e.g., 295 K), and B is the
emission bandwidth of the EUT in hertz.
Definition
Time window 15.303(k)
time window: An interval of time in which transmission is desired.
