Taking Floating Measurements
For taking
fl
oating measurements, the oscilloscope channel and Ext Trig inputs (3
M
Ω
) are isolated from the oscilloscope chassis and from each other. This allows
independent
fl
oating measurements with channel 1, channel 2, and Ext Trig (and
with channel 3 and channel 4 on four channel models).
The oscilloscope inputs
fl
oat even when the oscilloscope is connected to a
grounded power supply, a grounded printer, or a grounded computer.
Most other oscilloscopes share a common reference for the oscilloscope channel
and Ext Trig inputs. This reference is typically connected to earth ground through
the power cord. With common-referenced oscilloscopes, all input signals must
have the same common reference when you take any multi-channel measurements.
Without differential preampli
fi
ers or external signal isolators, common-referenced
oscilloscopes are not suitable for taking
fl
oating measurements.
Probe Connection
WARNING.
To prevent electrical shock, do not exceed the measurement or
fl
oating
voltage ratings for the oscilloscope input BNC connector, probe tip, or probe
reference lead.
