GxSmuSourceSetCurrentArray

Applies To

GX3104, GX3116e

Purpose

Sets the specified array of channels current settings when in constant current mode.

Syntax

GxSmuSourceSetCurrentArray (nHandle, nChannelListArraySize, panChannelListArray, dCurrent, pnStatus)

Parameters

Name
Type
Description
nHandle
SHORT
Handle to a GX3104 or GX3116e board.
nChannelListArraySize
SHORT
Specifies the number of channels in panChannelListArray. If nChannelListArraySize=-1, then panChannelListArray parameter is ignored (can be set to NULL) and settings will be applied to all the channels.
panChannelListArray
PSHORT
Array specifying the channels numbers to be set:
GX3104: 0 (GX3104_CHANNEL_1) to 3 GX3104_CHANNEL_4.
GX3116e: 0 (GX3116_CHANNEL_1) to 15 GX3116_CHANNEL_16.  
dCurrent
DOUBLE
Sets the specified channel’s current settings, the range for each current range is as follows:
GX3104:
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.

GX3116e:

0.      GX3116_SOURCE_CURRENT_RANGE_512MA: Source Current Range +/-512mA

1.      GX3116_SOURCE_CURRENT_RANGE_25_POINT_6MA: Source Current Range +/-25.6mA (default after reset).

2.      GX3116_SOURCE_CURRENT_RANGE_2_POINT_56MA: Source Current Range +/-2.56mA
pnStatus
PSHORT
Returned status: 0 on success, negative number on failure.  

Comments

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

Example

The following example sets channel 0 and 2 current:

 

SHORT nStatus;

SHORT  anChannelListArray [2];

// Fill channel array

anChannelListArray [0] = 0;

anChannelListArray [1] = 2;

GxSmuSourceSetCurrentArray (nHandle, 2, anChannelListArray, 2.5, &nStatus);
