4 test conditions
In order to measure the three-dimensional radio frequency radiated power and receiver performance of the mobile station, this standard specifies the spherical equivalent of the mobile station
The omnidirectional radiated power, referred to as Total Isotropic Radiated Power (TIRP) and spherical equivalent omnidirectional radiated
Sensitivity, referred to as Total Isotropic Radiated Sensitivity (TIRS). As the mobile station is in
The measurement results in the free space state and the measurement knots in various test states such as the left and right ears of the head model and the manpower model
Fruit may be different from each other, so this standard requires the need to carry out the corresponding sections of the communication system under the provisions of all the test state
test. For mobile stations that support multiple typical operating states, only tests are required in main machine mode.
With the development of technology and the emergence of the new standard of space RF radiation power and receiver performance testing methods to the corresponding
Product family test method prevail. If there is no relevant product family standard reference, then the standard of the 5.2 and 6.1 of the pass
Subject to the test method.
4.1 coordinate system
Figure 1 is a typical spherical coordinate system, Phi (φ) axis is the Z axis, Theta angle is defined as the measurement point and the Z axis
Angle, Phi angle is defined as the angle between the projection of the measuring point on the XY plane and the X axis.
After defining the spherical coordinate system, two orthogonal polarization directions for each measurement point are defined. the Phi polarization direction is defined as
Phi axis rotation direction, Theta polarization direction is defined as the direction of movement of theta axis rotation, as shown in Figure 2.
Figure 2 shows the antenna polarization diagram
This standard assumes that the EUT supports are in the Z-axis direction and therefore can cause the data points at Theta = 180 ° to be measured,
So the area of the spherical measurement coverage area (based on the 15 degree step) does not include | θ | > 165 °.
4.2 Measurement of general conditions
The test is carried out in the darkroom of the all-wave antenna, and the distance between the EUT rotation center and the center of the measurement antenna must be greater than
The minimum test distance R (see Appendix A), the entire measurement system in the implementation of all the tests required by this standard, its comprehensive expansion
The uncertainty should be less than 2.25 dB (see Appendix B). EUT support fi......
