IWR1642BOOST: RadarStudio: My TSW1400 can not capture anything, when i program frame duration with a relatively long vualue.

Hi all，

I am trying to capture moving targets within 3 meters，like torso movement， using iwr1642boost + mmwave DevPack+TSW1400. 

When i program frame duration with a relatively long vualue.like 200ms*200frame or 20ms*1000frame, the radarstudio will error. TSW1400 finished capture before frame ending and nothing was captured by TSW1400.  Sometimes i repeat click trigger button it will works as normal, while sometimes it not.

I want to know how to solve this problem.  Is this situation a common error？

 log output is given in the following.

[10:23:44] [RadarAPI]: ar1.SetupTSW1400()
[10:23:49] [RadarAPI]: TSW1400 set-up complete.

    Hi Kemeng,

    The TSW1400 has a capture timeout built into High Speed Data Converter Pro. Navigate to the HSDC Pro install Directory. Mine is at: C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro. Once there, go through 1400 Details\ADC files\. Here, you will find a file called AWR16xx_lvds_4Channel_ddr_4bit_par_centre_16_bit.ini -> this should correspond to the device driver you are using. Open this file with a text editor of your choice. Add this line at the bottom of the file
    Capture Timeout in Sec=120
    This will extend the capture timeout to 120 seconds.

    Regards,
    Justin
