3.3 Considerations for test setup

Give particular attention to the following aspects when handling power sensors.
Handling the TVAC‑compliant power sensor
1. NOTICE! Avoid contamination.
Always wear clean protective gloves when handling the TVAC‑compliant power
sensor to protect the power sensor and its environment from contamination.
2. NOTICE! Reduce outgassing to a minimum by following this bake-out procedure.
Vacuum bake the TVAC‑compliant power sensor for 100 hours at 85 °C at a pres-
sure lower than 10
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.
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.

3.4 Connecting to a DUT

For connecting the power sensor to a DUT, use the RF connector. See
"RF connector",
To connect to the DUT
1. Ensure that the RF connector of your DUT is compatible with the RF connector of
the power sensor.
