GxSmuSourceGetMode

Applies To

GX3104, GX3116e

Purpose

Returns the specified channel’s operation mode, constant Voltage or Constant Current.

Syntax

GxSmuSourceGetMode (nHandle, nChannel, pnMode, pnStatus)

Parameters

Comments

In constant voltage, the Source Voltage is constant while the current may change as a function of the load. In this mode the output behaves as a voltage source, and the output is limited by the current limit value, i.e. the load can draw current up to the current limit value. Applicable APIs are:

• GxSmuSourceSetVoltage

• GxSmuSourceSetCurrentLimit

• GxSmuSourceSetCurrentRange

In constant current, the Source current is constant while the output voltage changes as a function of the load. In this mode the output behaves as a current source, and the output is limited by the voltage limit value, i.e. the load can draw voltage up to the voltage limit value. Applicable APIs are:

• GxSmuSourceSetCurrent

• GxSmuSourceSetVoltageLimit

• GxSmuSourceSetCurrentRange

Example

The following example sets channel 1 to constant voltage mode:

SHORT nMode, nStatus;

GxSmuSourceSetMode (nHandle, GX3104_CHANNEL_1, GXSMU_SOURCE_MODE_CONSTANT_VOLTAGE, &nStatus);

GxSmuSourceGetMode (nHandle, GX3104_CHANNEL_1, &nMode, &nStatus);
