GxSmuSourceSetCurrentLimit

GX3104

Sets the specified channel’s current settings when in constant voltage mode.

GxSmuSourceSetCurrentLimits (nHandle, nChannel, dCurrentLimit, pnStatus)

Name	Type	Description
nHandle	SHORT	Handle to a GX3104 board.
nChannel	SHORT	Specifies the channel number (0-3): GX3104_CHANNEL_1 GX3104_CHANNEL_2 GX3104_CHANNEL_3 GX3104_CHANNEL_4
dCurrentLimitSource	DOUBLE	Sets the specified channel’s current settings, the range for each current range is as follows: 0. GX3104_SOURCE_CURRENT_RANGE_1000MA: Source Current Range -+/-1000mA. Supported by channel 1 only, channels 2-4 can be set up to +/-500mA. 1. GX3104_SOURCE_CURRENT_RANGE_250MA: Source Current Range -+/-250mA 2. GX3104_SOURCE_CURRENT_RANGE_25MA: Source Current Range -+/-25mA (default after reset). 3. GX3104_SOURCE_CURRENT_RANGE_2500UA: Source Current Range -+/-2.5mA 4. GX3104_SOURCE_CURRENT_RANGE_250UA: Source Current Range -+/-250uA 5. GX3104_SOURCE_CURRENT_RANGE_25UA: Source Current Range -+/-25uA 6. GX3104_SOURCE_CURRENT_RANGE_2500NA: Source Current Range -2.5uA to -1uA, and 1uA to 2.5uA
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

The function sets the specified channel’s current settings. The current value is in mA.

The following example sets channel 1 current limit settings:

SHORT nStatus;

DOUBLE dCurrentLimit;
