5 CALIBRATION AND CALIBRATION KIT
In transmission measurements the load match error has considerable influence if the
output of the DUT is poorly matched.
In reflection measurements the load match error has considerable influence in case of
poor output match and low attenuation between the output and input of the DUT.
220.127.116.11 Isolation Error
An isolation error (Ex) is caused by a leakage of the signal from the source port to the
receiver port escaping transmission through the DUT.
The Analyzer has typical isolation ratio of –140 dB, what allows to ignore this error for
most of measurements. The isolation error measurement is a non-mandatory option in
all types of calibration.
18.104.22.168 Reflection Tracking Error
A reflection tracking error (Er) is caused by the difference in frequency response
between the test receiver and the reference receiver of the source port in reflection
22.214.171.124 Transmission Tracking Error
A transmission tracking error (Et) is caused by the difference in frequency response
between the test receiver of the receiver port and the reference receiver of the source
port in transmission measurement.
