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.
How to: "To connect to non-screwable connectors (BNC)" on page 33
– SMA
Double-shielded SMA cables.
How to: "To connect to REF IN/REF OUT (reference = 1 GHz)" on page 35
– USB
Double-shielded USB cables.
How to: Chapter 3.1.8, "Connecting USB Devices", on page 32.
See also Chapter 15.6, "Measuring USB Cable Quality", on page 1262.
– LAN
At least CAT6 STP cables.
How to: Chapter 3.1.7, "Connecting to LAN", on page 31
●
Always terminate open cable ends.
●
Ensure that connected external devices comply with EMC regulations.
●
Use cables of the same type and equal length for connection to the I/Q and I/Q Bar
interfaces of the instrument.
How to: See "To connect instruments to the I/Q analog interface" on page 196.
●
Use the cable R&S SMU-Z6 for connection to the DIG I/Q interfaces of the instru-
ment. The cable is available under material number 1415.0201.02.
How to: "To connect instruments to the I/Q digital interface" on page 198.
●
Use the cable R&S DIGIQ-HS for connection to the HS DIG I/Q interfaces of the
instrument. The cable is available under material number 3641.2948.03.
