Preventing electrostatic discharge (ESD)
ESD is most likely to occur when you connect or disconnect an antenna modules.
Risk of electrostatic discharge (ESD)
Electrostatic discharge can quickly and imperceptibly damage or destroy
the electrostatic sensitive antenna modules.
Ground yourself to avoid electrostatic discharge (ESD) damage:
●
Using a wrist strap and cord, connect yourself to the ground.
●
Use a conductive floor mat and heel strap combination.
EMI impact on measurement results
Electromagnetic interference (EMI) affects the measurement results.
To suppress generated electromagnetic interference:
●
Use only the cables provided for the R&S
NRPM OTA power measurement
solution, and suitable shielded cables of high quality. For example, use dou-
ble-shielded RF and LAN cables.
●
Always terminate open cable ends.
●
Note the EMC classification in the data sheet.
●
When using the filtered cable feedthrough module R&S
NRPM-ZD3, make
sure that the chamber housing is grounded, since the feedthrough module is
grounded by the housing.
Since the antenna module receives signals in a wide band, also outside the
specified frequency bands, always measure in a controlled EM environment.
In particular, when working with the R&S
NRPM-Z3 interface module.
