1.This is the match of the test set port which has been selected as the source port. The test set intercon- nect reflection port must be terminated with a load standard from either the 85036B/E calibration kit (for the 87075C).

2.This is the match of any test port that is unselected (not in the measurement path). Only the source port of the test set is selected when you make a reflection measurement with 1-port calibration. Only the source and load ports of the test set are selected when you make a transmission or reflection mea- surement with 2-port calibration.

3.This is the match of the test set port which has been selected as the load port. A transmission or 2-port measurement is required for a test port to be selected as the load port. The test set interconnect trans- mission port must be terminated with a load standard from either the 85036B/E calibration kit (for the 87075C).

4.This is the match of the test set interconnect ports (transmission and reflection ports) with the test set in transmission, or 2-port mode. The selected test set test ports must be terminated with load standards from either the 85036B/E calibration kit (for the 87075C).

5.This is crosstalk of the test set measured between the test set’s interconnect ports, with shorts on the selected test ports. Crosstalk is computed by normalizing the result of an isolation measurement to a through measurement between the two ports such that the path losses are taken into account. Isolation is defined as the transmission signal measured between any two ports of the test system when these two ports are terminated with shorts. The specification assumes that the test set crosstalk has not been calibrated. Adjacent ports are defined as: 1&2, 3&4, 5&6, 7&8, 9&10, and 11&12.
