ZigBee Demodulation (1 minute 34 seconds)

See how to demodulate and measure a ZigBee 2.4 GHz, direct sequence, spread spectrum signal using offset QPSK with the Agilent 89600 Series vector signal analysis software.

The video begins by importing and displaying the special half-sine filter for a ZigBee signal. Then the signal is demodulated using offset QPSK with the imported filter shape applied and results shown in constellation, EVM versus time, and eye diagrams.

ZigBee Spectrum versus Time (1 minute, 16 seconds)

This demonstration uses the Agilent 89600 Series vector signal analysis software to show the power and spectrum characteristics of a ZigBee 2.4 GHz, direct sequence, spread spectrum signal.

The video shows first the basic spectral shape of a real ZigBee device signal and the ease with which the occupied bandwidth may be measured. Then you will see a spectrogram (spectrum versus time) that highlights packet characteristics of the ZigBee signal and the amplitude versus time measurement.
