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 10.
The RF connector type is an N connector. Use it to connect to the following:
●
Included attenuator, which is in turn connected to a device under test (DUT) or a
signal generator.
●
DUT or signal generator, directly connected.
●
Two-port device ("S-parameter device"), which in turn is connected to a DUT or a
signal generator.
For maximum measurement accuracy, tighten the RF connector using a torque wrench
with a nominal torque as specified in the following table.
