AWR1642BOOST: Confusion about data collection duration

Ritesh Tewari

Part Number: AWR1642BOOST

I am using DCA1000+AWR1642boost for the data collection. In sensorconfig section, the periodicity is set to 30ms, and the number of frames is set to 500, so the total data collection time should be 500x30 = 15000ms = 15sec. But my sensor keeps blinking and collecting data for 66 seconds and then stops. I did not click the stop-frame as I wanted to see for how long data is being collected. Also Stop trigger option is there till 15 second. Then all the buttons gets freezed. They get back to normal after 66 second again. During those 66 second the green light keep blinking, that mean it keep collecting data for 66 second although I set the duration for 15 second.

    Hi,

    In the snapshot provided

    Periodicity = 40ms

    Nb of Frames = 8

    If you are using a different configuration

    Periodicity = 30ms

    Nb of Frames = 300

    Then, 300 frames should be captured. There is some post processing performed, so it is expected that there will be some overhead.

    After the capture is completed, you should check the size of the .bin file created. This will give you confidence that you captured only 300 frames

    thank you

    I mistakenly uploaded the previous image. Here is the original sensorconfig image that I set up for the experiment. I think it should collect data for 15 seconds, but the green light keeps on blinking for 66 seconds, and then the postproc window appears automatically. It seems like data capturing is happening till the 66th second. Or is it capturing only for the first 15 seconds, and the remaining time it only blinks as post-processing is undergoing?

    Hi,

    In order to make sure that you have captured only 300 frames you can check the size of the generated .bin file.

    thank you
