BW 1 = Bandwidth of the path A output signal
BW 2 = Bandwidth of the path B output signal
Σ
BW = Extended bandwidth signal after combining path A and path B output signals
+ = Power combiner
Coupler = Directional coupler
Power sensor = Sensor of the R&S NRP family
SENSOR = Connection between R&S SMW and power sensor
3.1.2 Single R&S SMW with signal analyzer
This test setup includes a single R&S SMW, a power combiner, a directional coupler, a
vector signal analyzer and the device under test (DUT).
