AWR6843AOP: Getting access to ADC raw data for debug purposes.

Part Number: AWR6843AOP
Other Parts Discussed in Thread: MMWAVEICBOOST, DCA1000EVM,

Hi,

I am interested to get an access to a limited amount of raw samples of the ADC output to make initial signal evaluation(Saturation/IQ balance etc).

Currently waiting to receive the DCA1000EVM device to be able to record the ADC output, and have only AWR6843AOP and MMWAVEICBOOST.

Wondered whether there is any method that allows reading out a limited amount of samples from the ADC output for the initial analysis purposes.

Thank you for the response.

    Hello

    Are you asking if it possible to get access to Raw Data without using DCA1000?

    Wonder if you have checked the  CCS method in the following  Application note:

    mmwave Radar Device ADC Raw Data Capture (Rev. x)

    THank you,

    Vaibhav

    Thank you for the fast response Vaibhav.

    According to the referred document:

    “The raw data of the mmwave radar (xWRxxxx) can be captured using the Capture Demo provided in the mmWave SDK, or using Mmwave Studio provided in Mmwave Studio GUI tools.”

    Later, it mentions that:

    “Mmwave Studio, previously known as Radar Studio, supports two different platforms. One is DCA1000EVM Data Capture Card User's Guide, which has interface with xWRxxxx EVM that enables

    users to stream the ADC data over Ethernet. Another platform is TSW140x High Speed Data Capture/Pattern Generator Card which requires Mmwave devPack EVM and High Speed Data Converter

    Pro GUI User's Guide.”

    Does it mean that Capture Demo does not require any additional HW for ADC Raw data capture?

    If so - what is the maximal data transfer rate in this case?

    Thank you in advance for the reply.

    Hello

    As you are waiting for DCA1000 the suggested CCS was solution was to avoid the DCA or TSW board that uses the CCS memmory copy option.

    Both TSW and DCA boards use the LVDS options that go upto 900Mbps. 

    Capture demo need one of the above hardware because it sends data over LVDS interface.

    If you have not tried the CCS software based  copy memory method then we recommend you wait for the DCA1000 board and use it with the mmWave EVM.

    Thank you,
