FDwfAnalogOutModeGet(HDWF hdwf,

int

idxChannel, DwfAnalogOutMode *pmode)

Parameters:
-

hdwf – Open interface handle on a device.

idxChannel – Channel index.

mode – Pointer to variable to receive the generator mode option.

The function above is used to retrieve the current generator mode option for the specified instrument channel.

FDwfAnalogOutIdleInfo(HDWF hdwf,

int

idxChannel,

int

*pfsidle)

Parameters:

hdwf – Open interface handle on a device.

idxChannel – Channel index.

pfsidlec – Variable to receive the supported generator idle options.

The function above returns the supported generator idle output options. They are returned (by reference) as a bit
field. This bit field can be parsed using the IsBitSet Macro. Individual bits are defined using the DwfAnalogOutIdle
constants in dwf.h. These are:

Idle Constants

Idle Constant Capabilities

DwfAnalogOutIdleDisable

Supported on Electronics Explorer:
Channel 1&2 0V ouput
Channel 3&4. having 1 kΩ resistor to GND and diode

DwfAnalogOutIdleOffset

The idle output is the configured Offset level.

DwfAnalogOutIdleInitial

The idle output voltage level has the initial waveform value of the
current configuration. This depends on the selected signal type,
Offset, Amplitude and Amplitude Modulator configuration.

FDwfAnalogOutIdleSet(HDWF hdwf,

int

idxChannel, DwfAnalogOutIdle idle)

Parameters:
-

hdwf – Open interface handle on a device.

idxChannel – Channel index.

idle – Generator function option to set.

The function above is used to set the generator idle output for the specified instrument channel. The idle output
selects the output while not running, Ready, Stopped, Done or Wait states.

FDwfAnalogOutIdleGet(HDWF hdwf,

int

idxChannel, DwfAnalogOutIdle *pidle)

Parameters:
-

hdwf – Open interface handle on a device.

idxChannel – Channel index.

pidle – Pointer to variable to receive the generator function option.

The function above is used to retrieve the generator idle output option for the specified instrument channel.
