4.1 RF connector
The RF connector is used for connecting the power sensor to a device under test
(DUT) or a signal generator. See Chapter 3.4, "Connecting to a DUT", on page 15.
For maximum measurement accuracy, tighten the RF connector using a torque wrench
with a nominal torque as specified in the following table.
