6.1.1
RF measurements
Emissions tests
Test requirements
The equipment configured as shown in Figure 3 is for the conducted method. If the radiated method is
required, refer to test configurations in Clause 4. The EUT is arranged to communicate via a fixed carrier
frequency between its transmitter and a compatible receiver. If the devices provide two-way
communications, one should be designated as the transmitter under test. If the EUT is evaluated by a
conducted measurement on an external port, the EUT and its associated compatible transceiver should be
placed close enough to be able to establish a connection. Tests should be performed at the manufacturer's
recommended normal operating temperature and supply voltage.

—Test configuration
For conducted measurements, external RF attenuator and cable losses and instrumentation preamplifier
gains shall be taken into account. For radiated measurement, cable losses, instrumentation preamplifier
gains, and reference antenna factors shall be taken into account.
Transmitted digital sequences during emissions tests
The transmitted digital sequences during emissions tests shall be representative of those encountered in the
real system operation. If emissions parameters are sequence-dependent, then the worst-case sequence
expected to occur during normal operation shall be used.
Standard test frequencies for the emissions tests
For RF measurements, if the EUT is only capable of operation on a single frequency, then that is the
standard test frequency.
