Coupled port power:
•
Coupling (selected): The power level of each test port is the same. If the power of any test
port is set, the power of all test ports will change accordingly.
•
Decoupling (clearing): Set the power level for each test port separately and decouple the
Power. For example, if you want to measure the gain and reverse
isolation of a high gain amplifier, the input port of the amplifier
requires much less power than the output port. Power sweep can
also be performed using uncoupled power.
