Note:
1. Reference signal is defined as O-QPSK DSSS per 802.15.4, Frequency range = 2400-2483.5 MHz, Symbol rate = 62.5
ksymbols/s.
2.Reference sensitivity level is -85 dBm.
3.Due to low-IF frequency, there is some overlap of adjacent channel and image channel bands. Adjacent channel CW
blocker tests place the Interferer center frequency at the Desired frequency ± 5 MHz on the channel raster, whereas the
image rejection test places the CW interferer near the image frequency of the Desired signal carrier, regardless of the
channel raster.
