Parameters

Name
Type
Comments
nHandle
SHORT
Session identifier:
Board handle is used when communicating with the hardware. The Board handle session identifier is returned by calling DioInitialize or DioSetupInitialization.
nSource
SHORT
Measurement source:

1.      DIO_POWER_SUPPLY_VCC2_VOLTAGE: High Power supply Second VCC module. Second VCC module is controlled by the Gx5055 board installed in slot 13.
2.      DIO_POWER_SUPPLY_VEE_VOLTAGE: High Power supply VEE module. VEE module is controlled by the Gx5055 board installed in slot 5.
3.      DIO_POWER_SUPPLY_VDD_VOLTAGE: High Power supply VDD module. VDD module is controlled by the Gx5055 board installed in slot 5.
10.   DIO_POWER_SUPPLY_VCC1_CURRENT: High Power supply First VCC current module. First VCC current module is controlled by the Gx5055 board installed in slot 5.
11.   DIO_POWER_SUPPLY_VCC2_CURRENT: High Power supply Second VCC current module. Second VCC current module is controlled by the Gx5055 board installed in slot 13.
12.   DIO_POWER_SUPPLY_VEE_CURRENT: High Power supply VEE current module. VEE current module is controlled by the Gx5055 board installed in slot 5.
DIO_POWER_SUPPLY_VDD_CURRENT: High Power supply VDD current module. VDD current module is controlled by the Gx5055 board installed in slot 5.
pdMeasurement
PDOUBLE
Returned measurement, all measurements are rounded to 10mV and 10mA.
pnStatus
PSHORT
Returned status: 0 on success, negative number on failure.

Comments

The function takes measurement of the specified high power supply source:

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.
