You can use the Keysight 81000BR Reference Reflector to make a
Reflectance Calibration, and a Termination Calibration.
Reflectance Calibration
Use this procedure to calibrate the Return Loss module against a
component of known return loss.
1 Making sure all the connectors are clean, set up the instrument as
shown in Figure 107 on page -189 if you are using an External Source.
