Measuring the Power Transmitted Through
the Reflection Reference
Connect your a Reflection Reference Cable to a Power Meter and measure
the transmitted power, E
ref
. You can use E
ref
to calculate the front panel
delta, see “
Calculating the Front Panel Delta
” on page 195.
Figure 112 Measuring the Power transmitted through the Reflection Reference
Measuring the Power when there are No
Reflections
Next, terminate the mesurement 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 113 Measuring the Power with the Connector Terminated
This measured power for the termination parameter is called P
T
.
You can only measure the Front Panel Delta if you use the a Reflection
Reference Cable.
