One Stop Systems' CompactPCI load board is designed to verify a number of system and performance parameters. The load board determines hardware wiring accuracy and verifies that operating voltage is in accordance with CPCI standards.

The OSS-LB-6U utilizes eight test points for extremely accurate system readings including: +5v, +3.3v, +12v, V I/O, system ground, push-button reset (#PRST) and supply fail (#FAL). The #PRST and #FAL are enabled via the jumper selectable system slot. Each of the test points is a pin jack type accepting standard 0.08" tip probe. All four voltages are carefully monitored: an illuminated green LED signals system power is being properly maintained and a red LED indicates the measured load is not within ±5% of the nominal. The amount of load on each of the four voltages can be easily changed via DIPswitches. These 3-pole switches are binary coded to represent the amount of current employed. On-board scalable load is selectable from 1 Amp to 7 Amps for +5v and +3.3v and from 0.1 Amp to 0.7 Amps for +12v and -12v. V I/O is coded for resistance rather than current since there are two possible voltages: +5v and +3.3v. The board size is 6U x 160mm x 1 slot.
