1 Tips for Preventing Damage
Protect the input and output connectors
• Avoid repeated bending of cables; a single sharp bend can damage a
cable instantly and permanently.
• Limit the number of connections and disconnections to reduce wear.
• Inspect the connectors prior to use; look for dirt, nicks, and other signs
of damage or wear. A bad connector can ruin the good connector
instantly.
• Clean dirty connectors to prevent poor electrical connections and avoid
damage to the connector.
Protect the RF connectors
• Be careful not to bend, bump or flex any device under test (DUT)
connected to instrument (such as filters, attenuators, or large cables).
This will reduce the amount of strain placed on the connectors and the
mounting hardware.
• Ensure externally connected items are properly supported (not freely
suspended) from the connectors.
• Always use torque wrench and gauge tools for connecting RF
connectors.
• Do not mix 50 Ω and 75 Ω connectors and cables.
