Selecting Appropriate Calibration Method
The Agilent 4294A has three calibration types: user calibration, port extension
compensation, and fixture compensation. Table 6-1 shows each device connection and its
corresponding adapter selection and calibration. Calibration should be done according to
the particular requirements of each device connection. See "Adapter Setting" on page 67
for adapter selection.
