Description of Testing Environment
The working temperature range of ZM5202 is divided into the normal working
temperature range and the extreme working temperature range. Under the normal
working temperature range, the testing result of RF complies with the requirements
of 3GPP specifications, and its function is normal. Under the extreme temperature
range, the RF index basically complies with the 3GPP specifications, and the quality
of data communication is affected to a certain extent, but its normal function is not
affected. ZM5202 has passed the EMC test. Table 6-2 is the requirement for the
testing environment, and Table 6-3 lists out the instruments and devices that might
be used during the test.
