Include the Effects of Residual EVM<br />

<strong>on</strong> Meas-Based Model Evaluati<strong>on</strong><br />

Downloading the <strong>ADS</strong> Signal to the E4438C results in a residual EVM of approximately 1.22% @ 0<br />

dBm, Measured with the 89640 VSA<br />

RSS’ing the 1.22% residual EVM with the model simulati<strong>on</strong> results show improved agreement<br />

between simulated <strong>and</strong> measured results (e.g. EVM_RSS= sqrt(EVM_simulated^2 + 1.22^2) to<br />

reflect test equipment characteristics<br />
