AlazarGetParameterUL

Function Syntax

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

Get a device parameter as an unsigned long value.

Parameters

• handle – [in] Board handle

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

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

• retValue – [in] Parameter’s value

Returns

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

Related Enumerations

enum ALAZAR_PARAMETERS_UL

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

Values:

enumerator SET_ADC_MODE

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.

enumerator SET_BUFFERS_PER_TRIGGER_ENABLE

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.

enumerator GET_POWER_MONITOR_STATUS

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.

enumerator SET_EXT_TRIGGER_RANGE

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

enum ALAZAR_ADC_MODES

Analog to digital converter modes.

Values:

enumerator ADC_MODE_DEFAULT

Default ADC mode.

enumerator ADC_MODE_DES

Dual-edge sampling mode.
