AlazarDSPGetParameterFloat

Function Syntax

RETURN_CODE AlazarDSPGetParameterFloat(dsp_module_handle dspHandle, U32 parameter, float * result)

Generic interface to retrieve Float-typed parameters.

This function is called with an element of DSP_PARAMETERS_FLOAT as parameter. Depending on which value is selected, the function will query a different parameter internally and pass the return value to result.

This function returns ApiSuccess upon success, and standard errors otherwise.

Values:

DSP_FFT_POSTPROC_REAL_B = 0

IEEE754 single precision value of “b” for real FFT output value calculation “(Re + a) * b + c”. To set this parameter in your program, it is necessary to set it after AlazarFFTSetup() call, because this is where its default value is set.

DSP_FFT_POSTPROC_REAL_C

IEEE754 single precision value of “c” for real FFT output value calculation “(Re + a) * b + c”. To set this parameter in your program, it is necessary to set it after AlazarFFTSetup() call, because this is where its default value is set.

DSP_FFT_POSTPROC_IMAG_B

IEEE754 single precision value of “b” for imaginary FFT output value calculation “(Im + a) * b + c”. To set this parameter in your program, it is necessary to set it after AlazarFFTSetup() call, because this is where its default value is set.

DSP_FFT_POSTPROC_IMAG_C

IEEE754 single precision value of “c” for imaginary FFT output value calculation “(Im + a) * b + c”. To set this parameter in your program, it is necessary to set it after AlazarFFTSetup() call, because this is where its default value is set.

DSP_FFT_POSTPROC_SCALE_OUT_MAIN

IEEE754 single precision value of the scaler multiplier for the main output. To set this parameter in your program, it is necessary to set it after AlazarFFTSetup() call, because this is where its default value is set.

DSP_FFT_POSTPROC_SCALE_OUT_SEC

IEEE754 single precision value of the scaler multiplier for the secondary output. To set this parameter in your program, it is necessary to set it after AlazarFFTSetup() call, because this is where its default value is set.
