Page 5 of 19 3.1 DESCRIPTION OF TESTS 3.1.1 Occupied Bandwidth Emission Limits (a) On any frequency outside a licensee’s frequency block, the power of any emission shall be attenuated below the transmitter power (P) by at least 43 + 10 log(P) dB. (b) When measuring the emission limits, the nominal carrier frequency shall be adjusted as close to the licensee’s frequency block edges, both upper and lower, as the design permits. (c) The measurement of emission power can be expressed in peak or average values, provided they are expressed in the same parameters as the transmitter power. 3.1.2 Occupied Bandwidth The 99% power bandwidth was measured with a calibrated spectrum analyzer. 3.1.3 Spurious and Harmonic Emissions at Antenna Terminal The level of the carrier and the various conducted spurious and harmonic frequencies is measured by means of a calibrated spectrum analyzer. The spectrum is scanned from the lowest frequency generated in the equipment up to 10 GHz. At the input terminals of the spectrum analyzer, an isolator(RF circulator with on port terminated with 50ohms) and an 870 MHz to 890 MHz band pass filter is connected between the test transceiver(for conducted tests)or the receive antenna(for radiated tests) and the analyzer . The rejection of the band pass filter to signals in the 825-845 MHz range is adequate to limit the transmit energy from the test transceiver which appears to a level which will allow the analyzer to measure signals less than-90dBm. Calibration of the test receiver is performed in the 870-890 MHz range to insure accuracy to allow variation in the band pass filter insertion loss to be calibrated. 3.1.4 Frequencies At the input terminals of the spectrum analyzer, an isolator (RF pad) and a high-pass filter are connected between the test transceiver (for conducted tests) or the receive antenna (for radiated tests) and the analyzer. The high-pass filter is to limit the fundamental frequency from interfering with the measurement of low-level spurious and harmonic emissions and to ensure that the preamplifier is not saturated. 3.1.5 Radiation Spurious and Harmonic Emissions Radiation and harmonic emissions are measured outdoors at our 3-meter test range.
