FCC Part 15 Subpart B can be viewed here and covers 150 kHz to 30 MHz with a 50 μH 50 Ohm LISN used. Coducted limits are covered in § 15.107 and section (a) includes Quasi-peak and average requirements.
These requirements can be achieved by a variety of different LISNs with a transient limiter or attenuator commonly placed between the EUT and network. The associated power requirements of the EUT must be within the tolerances of the measurement device.
