The equipment shall comply with all the technical requirements of the present document which are identified as applicable in annex
44、 A at all times when operating within the boundary limits of the declared operational environmental profile. 4.2 General conditions of measurement 4.2.1 General This clause gives the general operational conditions. The product-specific operating conditions will be derived from the product descriptio
45、n and documentation and stated in the test report. The levels of the test signals shall be expressed either in terms of the power relative to 1 mW (dBm) for amplifiers or the field strength relative to 1 V/m (dBV/m) for antennas. 4.2.2 Equipment configuration Power and signal distribution, grounding
46、, interconnecting cabling and physical placement of equipment of a test system shall simulate the typical application and usage in so far as is practicable, and shall be in accordance with the relevant product specifications. Only configurations within the range of setting likely to occur in normal
