What does spurious emission in Zigbee's module inspection test?

Last Updated on：2023-01-30 09:55:10

It means the transmission of one or more frequencies other than the necessary bandwidth. The transmission levels of these frequencies can be reduced without affecting the transmission performance. Spurious emission includes harmonic emission, parasitic emission, intermodulation products, and frequency conversion products, except for out-of-band emission.

Test method: Enable the transmitter to transmit carriers at a rated power, reasonably set the VBW value in each observed frequency band, and measure the spur level.
