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
