Host connector
Lemo type host connector. You can plug it:
●
Directly to a compatible Rohde & Schwarz instrument
●
To a R&S NRP2 power meter base unit
●
Using an R&S NRP
‑
Z3 or R&S NRP
‑
Z4 USB adapter to a controlling device (PC or
other)
●
Using an R&S NRP
‑
Z5 USB hub to a controlling device (PC or other)
RF connector
Used to connect the power sensor to a device under test (DUT) or a signal generator.
Caused by their different frequency ranges, the R&S NRP
‑
Z power sensors have dif-
ferent RF connectors. Also, for maximal measurement accuracy, the RF connector
must be tightened using a torque wrench with a specific nominal torque.
Refer to the operating manual of your R&S NRP
‑
Z power sensor for information on
your connector and the allowed nominal torque.
4.4 Connecting the R&S NRP
‑
Z Power Sensors
When connecting the R&S
NRP-Z27/-Z28/-Z37/-Z98 sensors, there are additional
requirements to fulfill. Refer to the operating manual of the corresponding sensor for a
description on how to connect it.

Z Power Sensors
Risk of damage to the center pin of the RF connector
When connecting the power sensor, always rotate only the union nut of the RF connec-
tor. Do not rotate the sensor itself to avoid damage the center pin of the connector.
1. Refer to the operating manual of your R&S NRP
‑
Z power sensor to find out what
kind of RF connector your sensor has and the recommended nominal torque.
2. Insert the RF connector of the attenuator straight into the RF output of your DUT.
Do not tilt it.
