pseudodifferential channels are all referred to a common ground, but this
ground is not directly connected to the computer ground. Often this
connection is made by a relatively low value resistor to give some
isolation between the two grounds.

PCI eXtensions for Instrumentation—an open specification that builds
off the CompactPCI specification by adding instrumentation-specific
features
the maximum and minimum parameters between which a sensor,
instrument, or device operates with a specified set of characteristics
signal sources with voltage signals that are referenced to a system ground,
such as the earth or a building ground; also called grounded signal
