Return Loss of Input and Output Ports
1. Connect the equipment for a standard reflection measurement.
2. Calibrate the system with an open and a short.
3. Connect the appropriate RF port of the 11612A to the network analyzer
test port. Terminate the opposite port with a 50 ohm load.
4. Measure the return loss. Refer to the specifications listed in this
document.
Insertion Loss
1. Connect the equipment for a standard insertion loss measurement.
2. Calibrate the system with a through line.
3. Replace the through line with the 11612A.
4. Measure the insertion loss. Refer to the specifications listed in this
document.
The return loss of the terminating load should be at least 20 dB better than
the desired measurement value.
