Keysight N9923-90001 User’s Guide123Calibration for NA, CAT, and VVM ModesCalibration Method SummaryCalibration Method Summary— Mechanical Full 2-port Cal is ALWAYS the most accurate Cal method. Thequality of a Mechanical Cal is completely dependent on the quality of theOPEN, SHORT, LOAD standards and the quality of the standardconnections. Use the correct high quality standards to ensure the mostaccurate calibration.— QuickCal is ideal for DTF measurements. QuickCal should be performedwhen good accuracy is required and when using a jumper cable or adapter.— QuickCal is NOT recommended when the DUT has 3.5 mm-female orSMA-female connectors.—Even with the optional Load, phase accuracy begins to degrade whenthe return loss is greater than about 20dB.— CalReady is accurate ONLY when the DUT is directly connected at the testports and most accurate at room temperature.— For highest accuracy, a new QuickCal or Mechanical Cal should beperformed:—When the temperature changes more than about 10°F (5°C)—When the connection to the DUT requires a different jumper cable oradapters.—When any of the following measurement settings change: FrequencyRange, Power Level, IF BW, and Resolution.
