FDwfAnalogOutLimitationInfo(

HDWF hdwf, int idxChannel, double *pvMin, double *pvMax)

Parameters:

- hdwf – Open interface handle on a device.

- idxChannel – Channel index.

- pvMin – Minimum limitation value.

- pvMax – Maximum offset voltage or modulation offset percentage.

The function above is used to retrieve available the limitation range. This option is supported on Electronics

Explorer Analog Out Channel 3 and 4, Positive and Negative Power supplies, to set current or voltage limitation.

FDwfAnalogOutLimitationSet(HDWF hdwf, int idxChannel, double limit)

Parameters:

- hdwf – Open interface handle on a device.

- idxChannel – Channel index.

- limit – Value to set voltage offset in Volts or modulation offset percentage.

The function above is used to set the limitation value for the specified channel on the instrument. With channel

index -1, each enabled Analog Out channel limitation will be configured to use the same, new option.

Parameters:

- hdwf – Open interface handle on a device.

- idxChannel – Channel index.

- mode – Generator mode option to set.

The function above is used to set the generator output mode for the specified instrument channel. With channel

index -1, each enabled Analog Out channel mode will be configured to use the same, new option. This option is

supported on Electronics Explorer Analog Out Channel 3 and 4, Positive and Negative Power supplies, to set

current or voltage waveform generator mode.

The DwfAnalogOutMode options are:

 DwfAnalogOutModeVoltage

 DwfAnalogOutModeCurren
