2.7 Connecting Coaxial Cable
Connect the coaxial cable to the MP2110A coaxial connector. Refer to 2.10
“Precautions for Preventing Damage”.
2.7.1 Notes on Coaxial Cable Connection
WARNING
When signals are input to the MP2110A, avoid excessive
voltage beyond the rating. Otherwise, the circuit may be
damaged.
•
When output is used at the 50
Ω/
GND terminator, never feed any
current or input signals to the output.
•
Use the correct coaxial cable for connecting to the coaxial connectors of
the MP2110A, which are either SMA or K connectors. If the wrong
coaxial cable for the connector is used, there is a risk of damage to the
connector.
•
Tighten coaxial connectors to the correct torque (0.9 Nm). If the coaxial
connector is over tightened, there is a risk of damage to the connector,
which may prevent disconnection. If the connector is not sufficiently
tightened, correct measurement may be impossible.
•
When operating the MP2110A with other equipment, arrange so that
the co-axial cables are not accidentally pulled; if they are pulled
accidentally, the MP2110A may be dragged off the bench top and
damaged.
•
Always use a coaxial cable with sufficiently low loss matching the
signal to be measured. Correct measurement may be impossible if the
cable loss is too large.
•
Use a coaxial cable with an impedance of 50
Ω
.
Correct measurement may be impossible if the impedance is incorrect.
•
Keep the protective caps fitted to unused coaxial connector.
