Reflection Tracking Error (Er); Transmission Tracking Error (Et) - Agilent Technologies E5071C Manual

Reflection tracking error (Er)

A reflection tracking error is caused by the difference in frequency
response between the test receiver and the reference receiver of a
stimulus port in reflection measurements. This error can be defined as a
constant value for each stimulus port because the combination of the test
receiver and the reference receiver of a stimulus port is always the same.
The number of reflection tracking errors for the E5071C is simply the
number of stimulus ports you use.
Er1 Reflection tracking error of port 1
Er2 Reflection tracking error of port 2
Er3 Reflection tracking error of port 3
Er4 Reflection tracking error of port 4

Transmission tracking error (Et)

A transmission tracking error is caused by the difference in frequency
response between the test receiver of a response port and the reference
receiver of a stimulus port in transmission measurements. When a certain
port is a stimulus port, a transmission tracking error is defined for each of
the other ports. Therefore, the number of transmission tracking errors for
the E5071C is the total number of combinations of stimulus ports and
response ports.
