Gx3348SetDac

Sets the specified DAC‘s voltage

Gx3348SetDac (nHandle, nDac, dVoltage, pnStatus)

Name	Type	Description
nHandle	SHORT	Handle for the PXI board.
nDac	SHORT	DAC to set. 0. GX3348_DAC_RAIL_A: dedicated Rail A DAC. 1. GX3348_DAC_RAIL_B: dedicated Rail B DAC. 2. GX3348_DAC_RAIL_C: dedicated Rail C DAC.
dVoltage	DOUBLE	DAC Voltage (-20 to 30V are valid)
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

Each DAC can be programmed with a voltage ranging between -20V to 30V.

The following example initializes the board, returns the rail connecting Channel 12 of Group A, and returns DAC B voltage:

SHORT nRail, nStatus;

DOUBLE dVoltage;

Gx3348Initialize (1, &nHandle, &nStatus);

Gx3348GetChannelRail(nHandle, GX3348_GROUP_A, 12, &nRail, &nStatus);

Gx3348GetDac(nHandle, GX3348_DAC_RAIL_B, &dVoltage, &nStatus);

if(nRail== GX3348_RAIL_B)

printf(“Channel 12 in Group A is connected to DAC B in Rail B”);
