Key Features

The R&S

 

NRQ6 frequency selective power sensor sets standards in RF perfor-

mance and usability. Outstanding key features are:

●

Combines the advantages of a measurement receiver (dynamic range, linear-
ity & video bandwidth) and a conventional diode-based or thermal power sen-
sor (stability, absolute accuracy & source match).

●

Easy operation with features such as browser-based user interface, autoset
configuration, automatic frequency tracking or spectral preview (signal check).

●

Measurements in low RF level ranges that are beyond the range of classical
power meters. Faster measurements in the RF level range close to the lower
boundary of classical power meters.

●

Frequency selective measurements with adjustable bandwidth including a
built-in ACLR measurement function

For a detailed specification, refer to the data sheet.
