2.4 Damage Prevention Measures
• Do not apply an excessive voltage when inputting the signal to this instrument. The circuits may be destroyed.
• Terminate the output with 50
Ω. Do not feed current to the output. The load must be a 50 Ω pure resistor terminated at
ground potential.
• Before connecting the input and output terminals, ground the other equipment (including test circuits) with a ground
wire. (Static electric countermeasure)
• The outer and inner conductors of the coaxial cable may be charged as a capacitor. Therefore, discharge them with a
piece of metal before using the cable.
• This instrument contains hybrid ICs and other important circuits and parts. These parts are extremely vulnerable to
static electricity. Therefore, never remove the bottom cover.
• The hybrid ICs inside this instrument are hermetically sealed. Never break this seal. If the hybrid ICs are unsealed and
the instrument deteriorates performance as specified, note that the maintenance may be refused.
• Ventilation holes are drilled into the bottom cover. Be careful not to block the ventilation.
• To protect this instrument against electrostatic damage, place a conductive mat on the work bench, and wear a wrist
strap. Connect the other end of the wrist strap to the conductive mat, or the GND terminal of this instrument.
