Calibration for NA, CAT, and VVM Modes
Calibration Method Summary
Calibration Method Summary
—
Mechanical Full 2-port Cal
is ALWAYS the most accurate Cal method. The
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.
—
QuickCal
is ideal for DTF measurements. QuickCal should be performed
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.
—
CalReady
is accurate ONLY when the DUT is directly connected at the test
ports and most accurate at room temperature.
—
For highest accuracy
, a new QuickCal or Mechanical Cal should be
performed:
— 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.
QuickCal is only available on N991xA/2xA/3xA models.
