—Test facilities that may be used
Test configurations and setup
Clause 6 provides detailed tests of parameters related to RF emissions, such as peak transmit power,
emission bandwidth, and PSD. Those tests are similar to emission tests performed on most non-UPCS
devices. Clause 7 and Clause 8 provide tests that verify compliance with the monitoring and access
requirements that are unique to UPCS devices. These tests require observation of the electrical performance
characteristics of the EUT in the presence of controlled interference of a specific frequency, power level,
and modulation format. The monitoring and access tests have implications for the conducted and radiated
test setups.
The monitoring antenna refers to the EUT antenna used to monitor the RF signal on the channel prior to
transmission. In many cases, the monitoring antenna will be the same as the transmitting antenna. If it is
not, then the monitoring and access tests are further complicated by the need to ensure that the monitoring
antenna provides “coverage” that is at least equivalent to that which would be provided by the transmit
antenna.
This standard identifies six test configurations. Each configuration is discussed in a separate subclause as
shown in Table 1.
