Connect
splitter output 2
of the power sensor assembly from the
section to channel 0 of the PXIe-5172 using an SMB (plug) to SMB (m)
adapter.
Note
The
power sensor assembly
must match the configuration used in the
section, in which the power sensor is connected to
splitter output 1
and the signal generator is connected to the input port of the
power splitter.
The following figure illustrates the hardware setup.

Measurement uncertainty is based on the following equipment and conditions:
•
Rohde & Schwarz NRP-Z91 at 20 °C to 25 °C.
•
Harmonics from the signal generator are less than -30 dBc.
