ERROR VECTOR MAGNITUDE (EVM) & CONSTELLATION ANALYSIS

This view offers a simultaneous display of:

• A time-based display of the complex FFT I and Q samples from each symbol plotted in subcarrier order for

each symbol with successive symbols in time order. The I and Q subcarrier samples within a sample are

plotted spread over a time equal to the symbol duration.

• Constellation display in X-Y grid

• Error Vector Magnitude Measurement (P1)

• Frequency Error Measurement (P2)

• Sync Correlation Measurement of preamble symbols (P4)

• Relative Power of Channel Estimation symbols (P5)

• Relative Power of Header symbols (P6)

• Relative Power of Payload symbols (P7)
