Measuring Multiport Devices

Calibrating the Test System

After the test set has warmed up for at least two hours, you must

calibrate the instrument before making any measurements. To

determine the type of calibration appropriate for the measurements you

will be making, refer to the PNA Series Network Analyzers User Guide,

part number E8356-90001.

You will need to calibrate each measurement path separately and store

the calibration as an instrument state in the network analyzer. For

information on how to calibrate and store instrument states, refer to

the PNA Series Network Analyzers User Guide, part number

E8356-90001.

In the example setup shown in Figure 6-1, the following tests will be

made:

• Return loss on the DUT's input and 2 output ports (A and B)

• Insertion loss (or gain) between the DUT's input and port A

• Insertion loss (or gain) between the DUT's input and port B
