3 Terms, definitions and abbreviations
3.1 Terms and definitions
middle and high signal sections, the spatial location of optimum sensitivity point on high,
middle and low signal channels and the measuring antenna polarization shall be taken as
the reference location and reference polarization respectively. If the difference BETWEEN
the sensitivity of high and low signal channels measured which is based on the spatial
location of optimum sensitivity point on middle signal channels and test antenna
polarization AND the sensitivity on the middle signal channels is less than 3dB, then the
spatial location of the optimum sensitivity point and antenna polarization on middle signal
channels can be used as the uniform reference location and reference polarization on
high, middle and low signal channels.
4) It shall conduct EIS measurements for all signal channels within each section under
the corresponding reference location and reference polarization within the
above-mentioned sections respectively. And record the measurement results.
5) It shall establish connection on CDMA (cdma2000 lx) 850 frequency band for Module
2 according to the requirements of YD/T 1484, and select the high, middle and low signal
channels and launch Module 2 with the maximum power.
6) EUT location and test antenna polarization shall be adjusted according to the
reference location and reference polarization determined by step 3.
7) It shall rerun step 4). And record the EIS of each channel.
8) Difference between measurement results of step 7 and step 4 on each signal
