Figure 38: ISO-Channel Technology
Floating, Differential Signals
ISO-Channel technology implements a virtually ideal differential measurement system that
reads only the potential difference between the positive and negative terminals of the
amplifier. For each channel, the differential signals are isolated in that they are referenced to a
ground reference point that is not connected to earth ground. Ground loop problems are
eliminated by ensuring that only one ground reference is used for each channel in the
measurement system. The signal sources are isolated from each other and from the
measurement instrument.
