Question:

What are the procedures for compliance measurement for the fundamental emission power for licensed wideband (> 1 MHz) digital transmission systems?

Answer:

Attachment 971168 D01 Power Meas License Digital Systems v03r01 provides procedures for measuring power and unwanted emissions of wideband (> 1 MHz) digitally modulated RF signals that are acceptable to the FCC for demonstrating compliance for licensed transmitters.

Attachment 971168 D02 Misc OOBE License Digital Systems v02r02 provides emission measurement guidance for specific service rules.

Attachment 971168 D03 IM Emission Repeater Amp v01 provides basic guidance for intermodulation product spurious emission testing of frequency translating repeater system equipment and similar devices.

Note: 04/24/2023 Attachment 971168 D02 Misc OOBE License Digital Systems v02r02 was updated.Question and Answer #2 in Clause V. removed to reflect that channel-aggregated transmitter bandwidth limitations were removed from Part 90Y by FCC Report and Order 23-3.
