General Information
Preventing Damage to the Oscilloscope Inputs
Avoid damaging the oscilloscope inputs by knowing the approximate signal level
to be measured. Overpowering the front end can cause damage to the front end
components. The maximum input signal level of V-Series oscilloscopes is ±5 V.
When connecting probes, adapters, or cables to the Infiniium V-Series
oscilloscope, use caution to avoid damaging the oscilloscope’s channel input
circuits due to electrostatic discharge (ESD).
CAUTION
When a probe, adapter, or cable is connected to the V-Series oscilloscope, the
oscilloscope’s channel input circuits can be damaged by ESD. Avoid applying static
discharges to anything connected to the oscilloscope. Be sure the oscilloscope is
properly earth-grounded to prevent buildup of static charge. Wear a wrist strap or
heel strap.
CAUTION
Loose cables, much like loose capacitors, can hold electrostatic charges. The free end
of a cable touching a charged surface can cause oscilloscope input damage. Before
connecting any cable to an oscilloscope input, short the center and outer conductors
of the cable together to ground momentarily. Alternatively, connect to a 50 Ω
termination adapter to discharge the cables.
WARNING
Use Only Grounded Instruments.
Do not connect the ground lead of a probe to a potential other than earth ground.
Always make sure the probe and the oscilloscope are grounded properly.
