3.6 Modulation Analysis Measurement
[:SENSe]:EVM:NCEVm[:ENABle]?
Example
:EVM:NCEV 1
:EVM:NCEV?
Notes Before ccEVM, Remote Analyzer should be configured in Meas Setup\Global\Remote Analyzer Config.
See "Remote Analyzer Config" on page 1077
Dependencies Available on VXT3 platform only, and supports only the following radio standards:
–
802.11be 320 MHz with 320M bandwidth

CC-EVM
CCEVm
Cross-Correlated EVM
A technique applied for RMS EVM to suppress analyzer noise resulting
in lower EVM floor. A 2-channel analyzer, or two analyzers, demodulate
the same signal independently, and perform cross-correlation on the
error vectors to cancel out uncorrelated noise added by the analyzer
NC-EVM
NCEVm
Noise-Corrected EVM
A technique to improve EVM by compensating analyzer’s noise in EVM
domain. The contribution of analyzer’s noise to total EVM is estimated
and removed
