3.9.2.2 Result display for measurements on DSSS / CCK / PBCC signals
Fig. 3-13: Result summary list for measurements on DSSS/CCK/PBCC signals
●
Peak Vector Err, IEEE802.11b, g
Shows the peak vector error over the complete burst including the preamble in %
and in dB. The vector error is calculated according to the IEEE 802.11b definition
of the normalized error vector magnitude. For better orientation, the table also
shows the corresponding limits specified in the standard.
●
Burst EVM, IEEE802.11b, g
Shows the EVM (Error Vector Magnitude) over the complete burst including the
preamble in % and dB.
●
IQ Offset
Shows the IQ offset of the signal in dB. This is the IQ offset magnitude relative to
the RMS magnitude at the chip timing.
●
Gain Imbalance
