Fig. 4-3: Zeroing error message
This error is often caused by zeroing without switching off the test signal. If this is not
the cause, the sensor might have a hardware defect.

Data acquisition and parameters
Depending on the options that have been installed, up to four sensors can be connec-
ted to the R&S
NRP2. The sensors perform the complete power measurement from
the acquisition of the RF signal to every aspect of result processing. All important
parameters for configuring data acquisition are therefore entered in the "Sensor" menu.
The sensor menu provides access to all parameters concerning sensor settings like
measuring mode, filter, offset, gamma correction, level range and trigger settings.
The Sensor menu contains the following items:
●
Setting the measurement mode, on page 64
●
Offset correction, on page 76 and Filter/averaging, on page 79
●
Measurement ranges, on page 83
●
Effect of the RF source, on page 84
●
Trigger settings, on page 85
●
Trigger sequence control, on page 89
Some of the parameters listed above are not available for certain types of sensor.
4.2.1 Setting the measurement mode
The measurement mode is selected and configured in the "Mode" dialog box.
Regarding power measurement modes, find some background information to the fol-
lowing topics at the end of this section (see chapter 4.2.1.7, "Background information
on power measurement", on page 72):
●
"Acquisition interval" on page 72.
