Below are results from power spectra measurements of the CyMAC ADC, computed form 30 hours of time series data, compared to the performance of the Red Pitaya. The frequency resolution for the initial Cymac CSD is 2 Hz, and 216,000 spectra measurements are averaged together. As of now, it still looks like we haven't reached the correlated noise floor of the CyMAC. We have a few days worth of data to take from, so I'll look into using a longer period of time. |
