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 E5070B/E5071B is the total number of combinations of stimulus ports and
response ports.
