VTM ® Evaluation Boards
The Remote Sense PRM evaluation board is designed to work with all types of VTM ®
evaluation boards to facilitate testing of virtually any PRM ® /VTM combination. The VTM
evaluation board contains dual connectors designed to mate with J10 and J13 on PRM
evaluation board. The additional signal connector is used to transfer VTM signal pins, as
well as S+ and S- signals between boards. The S+ and S- signals are tied to the VTM output
using local sense resistors and can be used for implementing non-isolated remote sense
as described in a later section. Board also provides the ability to inject an AC signal for
measuring the loop response and break the isolation for non-isolated remote sense using
PRM and VTM.
