MDO4000C Series measurements are taken on actual acquisition data - providing as much data to the measurement algorithms as possible. The Keysight 4000 X-Series uses the lower resolution display data, which can produce measurements that are inaccurate and change with zoom settings.
Misinterpreting the Keysight measurements could lead you to draw the wrong conclusion, putting your overall design quality and integrity at risk.
