4. Tighten all screws at the rack brackets with a tightening torque of 1.2 Nm to secure
the R&S SMA100B in the rack.
To unmount the R&S SMA100B from a rack
1. Loosen the screws at the rack brackets.
2.
WARNING! The R&S SMA100B can be heavy, e.g., if fully equipped. Use a lifting
equipment, see also "Lifting and carrying the product" on page 19.
Bring the lifting equipment to shelf height.
3. Remove the R&S SMA100B from the rack.
4. If placing the R&S SMA100B on a bench top again, unmount the adapter kit from
the R&S SMA100B. Follow the instructions provided with the adapter kit.
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:
●
Use high-quality shielded cables, especially for the following connector types:
– BNC
Double-shielded BNC cables.
– SMA
Double-shielded SMA cables.
How to: "To connect to Ref In/Ref Out (reference = 1 GHz)" on page 33
– USB
Double-shielded USB cables.
How to: Chapter 3.1.8, "Connecting USB devices", on page 31.
See also Chapter 15.6, "Measuring USB cable quality", on page 752.
– LAN
At least CAT6 STP cables.
How to: Chapter 3.1.7, "Connecting to LAN", on page 30
●
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.
