AlazarGetParameterUL

Function Syntax

RETURN_CODE AlazarGetParameterUL(HANDLE handle, U8 channel, U32 parameter, U32 *retValue)

Get a device parameter as an unsigned long value.

Return

ApiSuccess upon success, or an error code. See RETURN_CODE for more detailed information.

Parameters

• [in] handle: Board handle

• [in] channel: The channel to control. See ALAZAR_CHANNELS for a list of possible values. This parameter only takes unsigned 8-bit values.

• [in] parameter: The Parameter to modify. This can be one of ALAZAR_PARAMETERS_UL.

• [in] retValue: Parameter’s value

enum ALAZAR_PARAMETERS_UL

Parameters suitable to be used with AlazarSetParameterUL() and/or AlazarGetParameterUL()

Values:

SET_ADC_MODE = 0x10000047UL

Sets the ADC mode. The value must be a member of ALAZAR_ADC_MODES. When this parameter is used, channels must be one or more channels OR’ed together. CHANNEL_ALL is not allowed.

SET_BUFFERS_PER_TRIGGER_ENABLE = 0x10000097UL

Configures the number of DMA buffers acquired after each trigger enable event. The default value is 1.

It is possible to make the number of buffers per trigger enable infinite by passing a value of 0xFFFFFFFF to this parameter. In this case, trigger enable essentially becomes a “start of acquisition” signal.

Remark

To set the number of buffers per trigger enable, this must be called after AlazarBeforeAsyncRead() but before AlazarStartCapture(), which means that AlazarBeforeAsyncRead() must be called with ADMA_EXTERNAL_STARTCAPTURE

Remark

This parameter is reset in between acquisitions.

GET_POWER_MONITOR_STATUS = 0x10000098UL

Queries the status of the power monitor on the board. The value returned is zero if there is no problem. If it is not zero, please send the value returned to AlazarTech’s technical support.

SET_EXT_TRIGGER_RANGE = 0x1000001CUL

Configure external trigger range. Parameter is as a member of ALAZAR_EXTERNAL_TRIGGER_RANGES

enum ALAZAR_ADC_MODES

Analog to digital converter modes.

Values:

ADC_MODE_DEFAULT = 0

Default ADC mode.

ADC_MODE_DES = 1

Dual-edge sampling mode.
