Appendix

shows how to connect a floating signal source to the STP connection box using
differential inputs. (A floating signal source is a voltage source that has no connection with
earth ground.)
Note:
For floating signal sources, we recommend that you provide a bias return path for the
differential channels by using the Open Layers Control Panel applet to enable 10 k
Ω
of
termination resistance. For more information, refer to
.
illustrates how to connect a nonfloating signal source to the STP connection box
using differential inputs. In this case, the signal source itself provides the bias return path;
therefore, you do not need to provide bias return resistance through software.
R
s
is the signal source resistance while R
v
is the resistance required to balance the bridge. Note
that the negative side of the bridge supply must be returned to analog ground.
