The CR-150-R5 is an evaluation board for any of the CR-11X CSP modules. The board has provisions to be powered either by a wall-mounted power supply (CR-24V, sold separately) or by the user's +/-12V power supply. There are 3 PC mountable BNC connectors included but not installed onto the board. There is provision for biasing the detector using 'AC coupling' and a 'test input' is included. Shielded housings are available for this board: the CR-150-BOX-R5, and the CR-150-BOX-R5-HV.
This is part of an 'a la carte' approach to constructing a CSP instrument. A CR-11X module, plus this CR-150-R5 eval board, plus the CR-150-BOX-R5 housing, plus the CR-24V power supply, and finally some assembly (including some soldering) will provide you with a complete CSP instrument.
