5.0 VTM Customer Boards
The half-chip PRM-RS Customer Board is designed to work with all types of VTM Customer Boards
to facilitate testing of virtually any PRM/VTM combination. Note that there are currently two basic
types of VTM Customer Boards. Both board types share many common features, including input
capacitance, output capacitance, and various test points. The main difference between the two board
types is the number of connectors. Before configuring a PRM/VTM setup, the user should identify
which type of VTM board is being used.
5.1 VTM Customer Board Type A (Single Connector)
The VTM Customer Board Type A contains a single power / signal header designed to mate with
only X01 on the half-chip PRM-RS Customer Board. The PRM output voltage, and VC signal are
transferred through this header when connected to a PRM Customer Board.
