Return Loss Measurement 7
Measuring the Power when there are No Reflections
Next, terminate the measurement patchcord so that there are no
reflections from the end. All the power measured by the sensor now, is due
to the non-ideal nature of the measurement system. This is our
termination parameter.
Figure 127 Measuring the Power with the Connector Terminated
This measured power for the termination parameter is called P
T
.
Measuring the Power Transmitted Through the Measurement Patchcord
Connect the measurement patch cord (the cable you will use to connect to
the Device Under Test, DUT) directly to a Power Meter and measure the
transmitted power, E
Meas
. You can use E
Meas
to calculate the front panel
delta, see Calculating the Front Panel Delta on page 209 and to calculate
the insertion loss, see Calculating the Insertion Loss of the DUT on
page 211.
