Remarks

PICS Item: HRDS28

EVM (error vector magnitude) is the magnitude of the error vector at the measured chip location. The error vector is the vector difference between the I/Q measured-signal phasor and the I/Q reference-signal phasor.

EVM (%rms) is the Root Mean Square of the error vectors, within the measurement interval, computed and expressed as a percentage of the square root of the mean power of an ideal signal.

The capture length over which EVM is measured is controlled by the instrument's MaxPacketLength and FramesUsed and settings:

• MaxPacketLength indicates the maximum length (in seconds) to expect for the 802.11b packet
• FramesUsed specifies the number of bursts to be averaged for an 802.11b test
