Measurement accuracy is affected by errors introduced by the Analyzer and measurement setup. The nature of these errors is varied some are systematically repeated, and some are random. Calibration is a process used to evaluate systematically repeated errors and mathematically exclude them from the measurement results in the correction process.


note

Be sure to properly calibrate if accurate measurements are required. Only a properly calibrated instrument provides the accuracy specified in the data sheet.


The section describes information about calibration, calibration kits and automatic calibration module (ACM):

General information about calibration (See General Information).

Working with calibration standards and calibration kits (See Calibration Standards and Calibration Kits).

Calibration method and procedures (See Calibration Methods and Procedures).

Power calibration with an external power meter, to maintain an accurate power level at the DUT input (See Power Calibration).

Calibration of receivers for accurate power measurements (See Receiver Calibration).

Mixer Calibration:

1.Scalar Mixer Calibration, requires no additional mixer. The mixer measurement is performed in frequency offset mode. This method allows for measurement of reflection parameters in vector form and transmission parameters in scalar form.

2.Vector Mixer Calibration is performed using an additional mixer. This method allows for measurement of reflection and transmission parameters in vector form, including phase and group delay time of the transmission coefficient.

Working with the automatic calibration module (ACM), which allows for simplification and speeding up of the analyzer calibration process (See Automatic Calibration Module).
