5.3.2. Statistics Display on a PC Connected to a Transceiver
The procedures in this section assume that a single Linux PC is connected to each transceiver.
To decode and display streaming MPEG-2 video, follow the guidelines for PC selection in
section 2.2.2.
5.4. Transmit Spectral Mask Compliance Test
Summary Description: This test nominally
*
confirms that Motorola UWB equipment complies
with FCC spectral mask specifications and that the transmit power spectrum is within the
limitations necessary to prevent interference with other frequencies. It has four components as
follows:
• A wideband compliance test that checks the EIRP compliance of UWB emission
between 960 MHz and 12 GHz. The power for each frequency band within this range is
specified in paragraph (c) of section 15.517 of the CFR 47, Part 15 (Code of Federal
Regulations. See section 12 for a full citation).
• A narrowband GPS interference test that considers the EIRP between 1164 – 1610
MHz. The power for each frequency band within this range is specified in paragraph (e)
of section 15.517 of the CFR 47, Part 15.
• A peak to average power test that considers the peak emitted power per MHz over a 50
MHz resolution bandwidth about the center frequency in which a UWB device emits the
greatest of power. The specification of this test can be found in paragraph (f) of section
15.517 of the CFR 47, Part 15.
• Adjustment of the above measurements for the antenna gain*.
During this test the UWB transceiver sends a continuous bit stream in unframed mode. In other
words, a single, very long frame is sent containing only one header and one payload.
Prerequisites:
• None.

Note that a measurement through wire and then adjusting for the antenna gain is not accepted by the
FCC, which requires open air tests that includes all antenna effects. Since open-air tests require an
outdoor test site and are far more time consuming and difficult, the approach outlined here is meant to
provide a nominal indication of compliance that can be done quickly in a lab environment.
