Vector Cancellation tool

This tool indicates the magnitude of the residual vector when the unit vector is summed with a vector that is different in level by "LvlDiff" dB and different in phase by PhsDiff (plus 180 deg). The Starting Phase and Phase Increment for the vertical axis can be set as can the Starting Level and Level Increment for the horizontal axis. A rejection contour highlights the region between a "pass" and a "fail" on the rejection level.
