Comments

The Marvin Test Solutions Gx7015A and Gx7005A high powered chassis include a built in, user programmable power supply system. They use a special backplane to deliver high power to the GX5055 pin electronics via the J5 PXI connector. The power supply is made up of two VCC high rail modules, one VEE low rail module, and one VDD module.

The GX5055 DIO is capable of controlling these modules by setting their voltages, and monitoring their voltage and current output.

Example

See the DioPowerSupplySetRailsVoltage for a complete example.
