IWR1843BOOST: Missing real-time data

Brogan Morton
Prodigy 10 points
Part Number: IWR1843BOOST
Other Parts Discussed in Thread: DCA1000EVM,

I am acquiring data from the IWR1843BOOST board via the DCA1000EVM board and mmWaveStudio software. I can successfully configure the board and capture all the data in the binary files without errors, but when I analyze the data I get intermittent periods of zero values. This occurs on all the receive channels. I have posted plots of the ADC data from each receiver across all chirps and over several adjacent frames, from no data loss(Frame 7), to intermediate data loss (frame 8) to large data loss (frame 9). The data loss waxes and wanes over the full acquisition period (100 frames). Any guidance as to how to troubleshoot this issue would be appreciated.

I have attached the log file with the information on the configuration used.
