DCA1000EVM: Difference in capturing raw IQ data via mmWave Studio and Out of the box demo in mmWave SDK

Part Number: DCA1000EVM

Hi, 

I understand, there are 2 ways to capture raw IQ data using DCA1000EVM and mmWave devices 

1. Use the Lua script or the GUI options in mmWave Studio 

2. Use the OOB demo in mmWave SDK and use the CLI commands. 

What are the differences between these two methods?

Thanks

    Hi Gayatri,

    Here are some points to note:

    • Both these tools use the same RF_API.dll which allows to communicate to the DCA1000 EVM. 
    • The DCA1000EVM captures LVDS data from the device and sends it to the host over ethernet.
    • The mmWave Studio is mainly a front-end evaluation and data capture tool that can be used to configure many things on the front end. It just has an MSS RF eval application running on the chip which takes RF Api instructions from the Studio application and relays them to the BSS accordingly.
    • mmWave Studio is GUI based and has scripting capabilities with lua.
    • Studio CLI is a command line-based tool that allows ADC data capture when the demo is running on the device. The studio CLI is used to both send configure the demo over UART and initiate DCA capture of LVDS data that is streamed out. The flexibility of configuration using studio CLI with respect to the front end is much less than that of Studio.
    • Studio CLI is especially useful when you need to capture both input and output of your signal chain.

    Hope this answers your question.

    Thanks for the detailed description.  Since the firmware used in both the cases are different, is there a difference in performance or in functionalities?

    No difference in the performance or functionality. Backbone of both firmware is same.
