3.2.15 Spurious Emissions §15.323 (d)
Emissions shall be attenuated below a reference power of 112 milliwatts as follows: 30 dB between the
channel edges and 1.25 MHz above or below the channel; 50 dB between 1.25 and 2.5 MHz above or
below the channel; and 60 dB at 2.5 MHz or greater above or below the channel. Systems that further sub-
divide a 1.25 MHz channel into X sub-channels must comply with the following emission mask: In the
bands between 1B and 2B measured from the center of the emission bandwidth the total power emitted by
the device shall be at least 30 dB below the transmit power permitted for that device; in the bands between
2B and 3B measured from the center of the emission bandwidth the total power emitted by an intentional
radiator shall be at least 50 dB below the transmit power permitted for that radiator; in the bands between
3B and the 1.25 MHz channel edge the total power emitted by an intentional radiator in the measurement
bandwidth shall be at least 60 dB below the transmit power permitted for that radiator. "B" is defined as
the emission bandwidth of the device in hertz. Compliance with the emission limits is based on the use of
measurement instrumentation employing a peak detector function with an instrument resolution bandwidth
approximately equal to 1.0 percent of the emission bandwidth of the device under measurement.
The DT-620 tunes up to 1930 MHz; therefore, in accordance with §15.33 (b) (1), the EUT was tested from
30 MHz to 19.3 GHz, and in accordance with §15.31(m) the EUT was tuned with the transmitter at a low
channel and an upper channel.
