Calibration Method Summary
— Mechanical Full 2-port Cal is ALWAYS the most accurate Cal method. The
— CalReady is accurate ONLY when the DUT is directly connected at the test
— For highest accuracy, a new Mechanical Cal should be performed:

quality of a Mechanical Cal is completely dependent on the quality of the
OPEN, SHORT, LOAD standards and the quality of the standard
connections. Use the correct high quality standards to ensure the most
accurate calibration.

Even with the optional Load, phase accuracy begins to degrade when
the return loss is greater than about 20dB.
ports and most accurate at room temperature.
— When the temperature changes more than about 10°F (5°C)
— When the connection to the DUT requires a different jumper cable or
adapters.
— When any of the following measurement settings change: Frequency
Range, Power Level, IF BW, and Resolution.
