Thus there are two sets of error terms, forward and reverse, with each set consisting of six error terms, as follows:

nDirectivity, Enr (forward) and Ena (reverse)

nIsolation, EXF and EXR

w Source Match, Esr and Esa

w Load Match, ELF and ELR

nTransmission Tracking, Err and Era

nReflection Tracking, Em and ERR

The analyzer’s test set can measure both the forward and reverse characteristics of the test device without you having to manually remove and physically reverse the device. The full two-port error model illustrated in Figure 6-46 depicts how the analyzer effectively removes both the forward and reverse error terms for transmission and reflection measurements
