Backreflection Measurements

Setting Up the Meter for Backreflection Measurements

To prepare the meter for backreflection measurements:

1.Ensure that the meter is powered off.

2.Set the power switch to ON, and allow the meter to stabilize.

3.Press the BR key to set the meter to Backreflection mode, which is displayed as BR on the meter.

4.Clean the output port on the front of the meter and the APC connector (green boot) of the measurement jumper, and connect this end of the jumper to the output port. Ensure that you are using the measurement jumper and not the calibration jumper, which is labeled as such. The output connector of the measurement jumper is user-selected and must be compatible with the input connector of the DUT.

For each wavelength at which measurements are to be made:

5. Press the λ key to select the required wavelength.
