2.10.1 Precautions on Electrostatic Discharge and Electrical Overstress
CAUTION
• When signals are input to the MP2110A, avoid
excessive voltage beyond the rating. Otherwise, the
circuit may be damaged.
•
Never feed any current or input signals to the output
connector.
•
As a countermeasure against static electricity, connect
the ground structures (for example, frame ground) of
external devices, including experimental circuits, to the
ground terminal of the MP2110A by using ground wires
before connecting the IO connector.
Shorten ground wires as much as possible.
•
To the input connector of the MP2110A, connect an
attenuator that can protect the MP2110A without
affecting measurement results. An attenuator with a
bandwidth of 40 GHz or more is recommended.
•
The outer conductor and core of the coaxial cable may
become charged as a capacitor. Use any metal to
discharge the outer conductor and core before use.
•
The MP2110A has many important circuits and parts
including hybrid ICs.
These parts are extremely sensitive to static electric
charges, so never open the case of the MP2110A.
•
To prevent the risk of damage to the MP2110A from
static electric charges, always use an antistatic mat on
the workbench and ensure that the operator wears a
grounded wrist strap.
Always ground the wrist strap to the workbench
antistatic mat or the frame ground of the MP2110A.
