Return Loss Measurement

A Background to Return Loss Measurement

194

Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Sixth Edition

If we substitute equation 3 into equations 2 and 4, this gives us the
following two equations:

If we subtract P

para

from equations 5 and 6, this gives us the following

equations:

If we divide equation 8 by equation 7, this gives us the following equations:

Thus we can use the equation below to calculate return loss:

The return loss of the reference reflection is given by:
