3.1.5 Considerations for test setup
Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:

cables.
●
Always terminate open cable ends.
●
Ensure that connected external devices comply with EMC regulations.
Regarding length and quality, the following requirements have to be met for cable that
are directly connected to the R&S ZNB/ZNBT:
