Fig. 4-99: Sensor test report, page 2
Page 2 shows the results with attached attenuator, if applicable.
Differences up to 0.02 dB at room temperature are absolutely normal and are due to
the uncertainty in the calibration of the sensor and the power reference. Greater differ-
ences can be caused by high/low ambient temperatures but also by a damage to the
sensor.
With multipath power sensors (R&S NRP-Z11, R&S NRP-Z21/22/23/24/28, R&S NRP-
Z31 and R&S NRP-Z91/92/98), the R&S NRP2 displays the test result of each individ-
ual path separately.

Exceeding the tolerance limits will result in a test failure. The factory-set default set-
tings depend on the sensor and are in line with the data sheet values. They are appli-
cable in the entire ambient temperature range. If the base unit and the sensors are not
used at temperature extremes, the tolerance limits can be restricted so that any dam-
age to the sensor can be detected even more quickly.

Defines the test limit range.
"Sensor"
Tolerance limits for the sensor section only.
"Sensor &
Pad"
Tolerance limits for the combination of the sensor section with
attached attenuator.
Set to defaults ← Config…
Resets the factory-set default settings.
