Power calibration plane
External power meters must be configured with their connection type and device
address before they are available as additional receivers ( [Cal] > "Power Cal Settings"
> "Power Meters"). Configured power meters appear in many control elements of the
R&S
ZNL, e.g. in power calibration dialogs.
R&S
FPL1-K9
With this software license, a R&S
ZNL with spectrum analysis option R&S
ZNL-B1 can
perform power sensor measurements in spectrum mode, using power sensors of the
R&S
NRP-Zxy family. The power sensors can be connected via USB or via the Sensor
connector on the rear panel (see
).
For a description, see the spectrum analysis help or manual.

Zeroing
Zeroing calibrates the external power meter by adjusting its reading at zero signal
power. For this purpose, the RF cable between the analyzer and the power sensor
must be disconnected (see tips below!). R&S power sensors and power meters auto-
matically detect the presence of any significant input power. This aborts zeroing and
generates an error message. Zeroing can take a few seconds, depending on the power
