Connecting a Floating Signal Source to the NI 9234E
The NI 9234E can also provide an IEPE excitation current for each
channel to measure ground-referenced or floating IEPE sensors.
Typical IEPE sensors have a case that is electrically isolated from
the IEPE electronics, so connecting the sensor to the NI 9234E
results in a floating connection even though the case of the sensor
is grounded.
