RM3 SERIES BACKREFLECTION METER

USER’S MANUAL

5.Attach the appropriate detector adapter to the detector on the front of the meter.

6.Connect the output connector of the measurement jumper to the detector adapter. This end of the measurement jumper is user-selected and must be compatible with the input connector of the DUT.

7.Press the Power key to set the meter to Power mode. When in Power mode, the meter displays P at the beginning of the reading, and no “rel” is displayed, for example, P = -9 dBm.

8.Press and hold the Power key until the display on the meter clears.

9.Release the Power key. The display reads 0.00 dB, and the loss of the measurement jumper is subtracted from the DUT loss or power measurements to be made (Figure 7).

Figure 7: Loss and Power Measurements

For loss and power measurements below -50 dBm:

10.Ensure that the detector is covered, for example, that the detector cap is on or the output connector is connected to the detector. This dark measurement current is subtracted from future loss and power measurements.

11.Press the Store ID key. The key lamp lights to indicate that the user-stored value of ID (the dark signal from extraneous sources) is used to calculate the DUT loss or power. If the detector is not sufficiently covered, the message “Too Much Light” is displayed. If theDI value is not stored before a measurement is made, the last value stored is used.

Measuring Power

In Power mode, absolute power measurements are displayed in dBm. To make a power measurement of a DUT after performing the setup steps in the Setting Up the Meter for Loss and Power Measurements section:

1.Press the Power key to set the meter to Power mode.

2.Press the λ key to select the wavelength at which the measurement is to be done.

3.Clean the output connector of the measurement jumper and the input connector of the DUT, and connect the two connectors.
