B3 Checking Mismatched Loads
The correct operation of the calibrated mismatch loads may be checked using the
equipment available for other tests. Place the Directional Power Meter between the
driving amplifier and the load to be tested. Adjust the generator to 500MHz, output on.
Measure the forward and reverse powers. The return loss is calculated at
RL = 10 log (PR/PF).
