Comments |
nHandle |
SHORT |
Session identifier:● Board handle is used when communicating with the hardware. The Board handle session identifier is returned by calling GtDio6xInitialize or GtDio6xSetupInitialization. |
nSource |
SHORT |
Used to select the power supply module to program:0. GTDIO6X_POWER_SUPPLY_VCC: Selects to read back from the VCC module. 1. GTDIO6X_POWER_SUPPLY_VCC2: Selects to read from the VCC2 module. 2. GTDIO6X_POWER_SUPPLY_VEE: Selects to read back from the VEE module. 3. GTDIO6X_POWER_SUPPLY_VDD: Selects to read back from the VDD module. |
pdCurrent |
PDOUBLE |
Used to return the voltage level read back of the module selected in the nSource parameter. |
pnStatus |
LONG |
Returned status: 0 on success, negative value on failure. |
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 GX5960 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 GX5960 DIO is capable of controlling these modules by setting their voltages, and monitoring their voltage and current output.
See the GtDio6xPowerSupplySetRailsVoltage for a complete example.
