5. CONDUCTED SPURIOUS EMISSIONS
5.1.Block Diagram of Test Setup
5.2.Limit
In any 100kHz bandwidth outside the frequency bands in which the spread spectrum
intentional radiator in operating, the radio frequency power that is produced by the
intentional radiator shall be at least 20dB below that in the 100kHz bandwidth within the
band that contains the highest level of the desired power.
5.3.Test Procedure
Use the test method descried in ANSI C63.10:
The transmitter output was connected to a spectrum analyzer, The resolution bandwidth is set
to 100 kHz, The video bandwidth is set to 300 kHz and measure all the emissions with peak
detector.
Note: The cable loss and attenuator loss were offset into spectrum analyzer as an amplitude
offset.
5.4.Test result
PASS (The testing data was attached in the next pages.)
