Methods of Measurement of the Electromagnetic and Operational Compatibility of UPCS Devices
determination of the average burst length. If there is no level that is 20 dB below the peak, then analyze the
complete sweep and include all of the wideband waveform that occurs during the sweep time in the
computation of average burst length.
Sum the values of the sample points (in linear units of power) and divide by the sample frequency to obtain
the total pulse energy in the 3 kHz bandwidth, then divide by the average duration of the wideband input
pulse to obtain the average pulse power. If the result is less than PSD
limit
, the EUT passes the PSD
requirement.

power waveform measured with 3 kHz RBW
Emissions
Unless otherwise specified, the conducted method is the preferred method of measurement for in-band
emissions. The radiated method may be used in-band if the EUT has nondetachable antenna(s), and should
be used generally for out-of-band tests. A free-space environment or equivalent should be used in the
radiated emission test. The general requirements for conducted and radiated tests are given in Clause 4 of
this standard.
In-band unwanted emissions
The equipment is configured as shown in Figure 3 and using the settings listed in Table 5 as follows.
In the region between 1B and 2B from the center of the RF carrier, the measured emission level (measured
with 1% of emission bandwidth) shall not exceed 30 dB below the permitted peak power for the EUT.
In the region between 2B and 3B from the center of the RF carrier, the measured emission level shall not
exceed 50 dB below the permitted peak power for the EUT.
