GxSmuSourceSetVoltageClamps

GX3116e

Sets the specified channel’s voltage limits high and low settings when in constant current mode.

GxSmuSourceSetVoltageClamps (nHandle, nChannel, dVoltageClampHigh, dVoltageClampLow, pnStatus)

Name	Type	Description
nHandle	SHORT	Handle to a GX3116e board.
nChannel	SHORT	Specifies the channel number (0-15): GX3116_CHANNEL_1 - GX3116_CHANNEL_16
dVoltageClampHigh	DOUBLE	Sets the specified channel’s voltage limit high settings when in constant current mode. Voltage range is -2.0V to +10.5V.
pdVoltageClampLow	DOUBLE	Sets the specified channel’s voltage limit low settings when in constant current mode. Voltage range is -2.0V to +10.5V.
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

Sets the specified channel’s voltage limits high and low settings when in constant current mode. The voltage range is -2.0V to +10.5V.

The user can call the GxSmuGetStatusRegisterChannel() API at any time, in order to find out if at any time the limits were met.

The following example sets channel 1 to constant current mode, sets the high voltage limit to +10V and the low limit to -1.0Vreturns the settings:

SHORT nStatus;

DOUBLE dVoltageClampHigh, dVoltageClampLow;
