module appears. The <RL> value should be the same value as entered for
<RLref>.
Measuring the Termination Parameter
11 Terminate the cable so that there are no reflections coming from the end. You
can do this by wrapping the fiber five times around the shaft of a screwdriver
(or some similar object with a diameter of around 5 mm).
12 Press [Menu]. Move to <Terminated Calibration> and press Enter. The
instrument measures the power reflected by the component. The instrument
measures and sets the termination parameter.
Measuring the Return Loss of the Reference Cable
To measure insertion loss and the front panel delta, you must measure the return
loss of a reference cable. The reference cable must be a fiber with a Diamond
HMS-10/Agilent/HRL and Diamond HMS-10/Agilent connector.
