Port Return Loss

Port Return Loss
An Agilent 8517B test set is required to perform this test.
1. Disconnect the 8511B from the GPIB, the test set IF interconnect and
the RF source signal. Leave it connected to the line power.
2. Place the 8517B test set on top of the 8511B. Connect the
8517B test set in the system by connecting the GPIB, the test set IF
interconnect, the RF source power, and the line power to it.
3. Turn on the 8511B and treat it like a device under test. You will use the
8517B test set to make S11 measurements of each port on the
8511B.
4. Perform the calibration at the end of the cable and take care to avoid
overly sharp cable bends (defined in the cable manual). Then measure
the return loss of each port on the 8511B.
