— O,S,L is ALWAYS the most accurate Cal method. The quality of a O,S,L is
— QuickCal is ideal for DTF measurements. QuickCal should be performed
— Present Cal is ONLY useful for DUT connections made at the RF Out port
— For highest accuracy, a new QuickCal or O,S,L Cal should be performed:

completely dependent on the quality of the OPEN, SHORT, LOAD standards.
Use the correct high quality standards to ensure the most accurate
calibration.
when good accuracy is required and when using a jumper cable or adapter.
— QuickCal is NOT recommended when the DUT has 3.5 mm-female or
SMA-female connectors.
— Even with the optional Load, phase accuracy begins to degrade when
the return loss is greater than about 20dB.
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.
