VTM ® Evaluation Boards
The 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.
The TM feedback of the VTM is also transferred through the additional signal connector
to make connection with VT pin of the PRM to enable temperature compensation in
Adaptive Loop configuration.
