4.5 Considerations for test setup
Cable selection and electromagnetic interference (EMI)
Electromagnetic interference (EMI) can affect the measurement results.
To suppress electromagnetic radiation during operation:
●
Use high-quality shielded cables, especially for the following connector types:
– BNC
Double-shielded BNC cables.
How to: "To connect to pluggable connectors" on page 25
– SMA
Double-shielded SMA cables.
How to: "To connect to screwable connectors" on page 25
– USB
Double-shielded USB cables.
How to: Chapter 4.8, "Connecting USB devices", on page 23.
– LAN
At least CAT6 STP cables.
How to: Chapter 4.7, "Connecting to LAN", on page 22
●
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 R&S SMA100B 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.
