Considerations for test setup

Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
● Use high-quality shielded cables, for example:
– Double-shielded data cables for connecting external devices. The length of
data cables must not exceed 3 m.
– Shielded cables (RG58/U coaxial cable) for signal transmission connec-
tions. The length of signal cables must not exceed 1 m.
– Double-shielded USB cables. The length of passive USB cables must not
exceed 1 m.
– CAT6+ LAN cables, e.g. RJ-45 with a length ≤3 m.
