AWR1443: Limited Data Size and Measurement Time in mmWave Studio

Shenghang Luo

Part Number: AWR1443


Hi,

I am using the AWR1443 and DAC1000 devices to measure the raw data with mmWave Studio.

The problem is I took a 10-minute measurement, but I only got around 3 mins data. And after several 10-minute measurements, the data size is exactly the same. 

I am wondering whether only the file called adc_data.bin includes all the data we want, or we need to use those files called adc_data_Raw_1,  adc_data_Raw_2, too.

And if the data size or measurement time is limited, how could we increase it?

Thanks,

Peter

    Hi,

    There should not be a time limitation with the DCA1000 data capture.

    The files adc_data_Raw_1,  adc_data_Raw_2... will be automatically generated when the data size is larger than 1Gb

    Do you see this behavior consistently?

    Thank you

    Peter,

    As stated in the mmWaveStudio User Guide:

    -----------------------------------------

    The file name to store the raw ADC data is given by the user in the SensorConfig Tab.

    The DCA1000 EVM appends “Raw_n” to the file name given by the user. After 1 GB of capture, the DCA1000 EVM will start capturing the data into another file.

    Each subsequent file will have the test “Raw_n” appended to the user given filename where n is a number starting from 0.

    For example, if the user given filename is adc_data.bin, after the capture, user will see adc_data_Raw_0.bin, adc_data_Raw_1.bin etc. files in the mmWaveStudio\PostProc (default location of the raw ADC data files) folder.

    -----------------------------------------

    You also will need to post process each raw ADC .bin file separately. The post process step will not process all of the saved raw ADC .bin files at once.

    You can refer to the DataCaptureDemo_xWR.lua script that is included in the mmWaveStudio installation for the API calls to complete these actions.
