ADC32RF45EVM: HSDC Pro Capture and analysis Window difference

Aravind Venkitasubramony

Part Number: ADC32RF45EVM

I have a couple of questions on the capture modes of the HSDC Pro. It was not clear in the user guide.

1. If I have averaging enabled with 8 number of captures and the # of samples is set to 65536 and the analysis window set to 8192, does it mean that a total of 65536 * 8 samples is captured and then the first 8192 samples of each of the 65536 blocks is FFTed and then averaged to give the output ?

2. If I have continuous capture enabled with the above setting, is it a rolling average of the last 8 captures or every time the above operation is continued and a new non overlapped average FFT is displayed?

Thanks

Aravind,

Yes, only the analysis window number of samples will be FFTed and averaged.
Continuous capture doesn’t do any averaging. It replaces the old data with the new capture every time.

Jim
