Evaluating Balanced Devices (balance-unbalance conversion function)

Measurement parameters of balanced devices

Turn on the balance-unbalance conversion function to measure the following parameters.
o Mixed mode S-parameter
o Imbalance parameter
o CMRR (Common Mode Rejection Ratio)
Mixed mode S-parameter
By turning on the balance-unbalance conversion function, you can obtain the S-parameter
of the balanced port separately for 2 modes, the differential mode and the common
mode.Figure 7-8 shows the notation of the S-parameter in balance measurement (mixed
mode S-parameter).
Figure 7-8 Notation of mixed mode S-parameter
Figure 7-9 to Figure 7-11 show the mixed mode S-parameter when measuring each
balanced device.
