4. Radiated and conducted emissions test methodology
To perform the RF emission tests in Clause 6 and the monitoring and access tests in Clause 7 and Clause 8,
it is necessary to have controlled RF paths between the EUT and the measurement instrumentation, as well
as between the EUT and the interference generators. If the EUT requires a companion device to operate,
there must also be a controlled RF path between the EUT and its companion device.
