Description

RFMXSPECAN_VAL_SPECTRUM_FFT_OVERLAP_MODE_DISABLED

0 (0x0)

Disables the overlap between the chunks.

RFMXSPECAN_VAL_SPECTRUM_FFT_OVERLAP_MODE_AUTOMATIC

1 (0x1)

Measurement sets the overlap based on the value you have set for the RFMXSPECAN_ATTR_SPECTRUM_FFT_WINDOW attribute. When you set the Spectrum FFT Window attribute to any value other than None, the number of overlapped samples between consecutive chunks is set to 50% of the value of the RFMXSPECAN_ATTR_SPECTRUM_SEQUENTIAL_FFT_SIZE attribute. When you set the Spectrum FFT Window attribute to None, the chunks are not overlapped and the overlap is set to 0%.

RFMXSPECAN_VAL_SPECTRUM_FFT_OVERLAP_MODE_USER_DEFINED

2 (0x2)

Measurement uses the overlap that you specify in the RFMXSPECAN_ATTR_SPECTRUM_FFT_OVERLAP attribute.
