Considerations for test setup
Give particular attention to the following aspects when handling power sensors.
Handling the R&S NRP18S
‑
xx power sensor
►
CAUTION!
Hot surfaces. Under certain conditions, the maximum surface tempera-
tures of the power sensor can exceed the limits defined in the EN
61010-1 stan-
dard, safety requirements for electrical equipment for measurement, control and
laboratory use.
Provide protection as follows:
a) Ensure that unintentional contact with the power sensor is impossible.
b) Wear heat-protective gloves when touching the power sensor after operation.
EMI impact on measurement results
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded cables, for example, double-shielded RF and interface
cables.
●
Always terminate open cable ends.
●
Ensure that connected external devices comply with EMC regulations.
Signal input and output levels
Information on signal levels is provided in the data sheet. Keep the signal levels within
the specified ranges to avoid damage to the product and connected devices.
The test limits specified on the name plate apply only if the power sensor is operated
together with the RF power attenuator supplied. If the power sensor is operated without
attenuator, the lower test limits of the R&S NRP18S power sensor apply, as specified
in the data sheet.
Preventing electrostatic discharge (ESD)
Electrostatic discharge is most likely to occur when you connect or disconnect a DUT.
►
NOTICE!
Electrostatic discharge can damage the electronic components of the
product and the device under test (DUT).
Ground yourself to prevent electrostatic discharge damage:
a) Use a wrist strap and cord to connect yourself to ground.
b) Use a conductive floor mat and heel strap combination.
