Measuring S-Parameters using a Two-Port Calibration
Measuring S-Parameters using a
Two-Port Calibration
This section describes how to perform a two-port calibration. Once done,
this calibration can be used with all types of S-parameter measurements.
It should be noted that other types of error correction, though not as
accurate as a two-port calibration, allow faster measurement speed.
Therefore, if measurement speed is of more importance than highest
accuracy, you may want to use a different type of error correction than
the two-port calibration. See the table below for a list of all possible
calibration choices for S-parameter measurements.
TIP
An optimum calibration is critical for achieving best measurement
accuracy. Refer to
Chapter 6, “Calibrating for Increased Measurement
for detailed information about all of the various aspects of
calibration.
