Figure 6.12 Port Z conversion
To enable/disable the port impedance conversion
function, toggle Port Z Conversion softkey.
To enter the value of the simulated impedance of Port 1,
use Port 1 Z0 softkey.
To enter the value of the simulated impedance of Port 2,
use Port 2 Z0 softkey.
6.3.2 De-embedding
De-embedding is a function of the S-parameter transformation by removing of some
circuit effect from the measurement results.
