AWR2243: Acquired frame in cascade mode

Part Number: AWR2243
Other Parts Discussed in Thread: MMWCAS-RF-EVM, TDA2

Hi Experts,

My customer is using MMWCAS-RF-EVM and MMWCAS-DSP-EVM. The acquired data is smaller than expected. The first frame looks lost. Is our setting not correct or is it a know issue?


Lua_Script : The problem happens with the script that came with mmWaveStduio
e.g.) the acquired frame size is 9 Frame though we set it to 10 Frame

Regards,
Ken

    Hello Ken,

    Yes, these are known limitations of the cascade platform.

    - The first frame may be corrupted in every capture. It is recommended to ignore the first frame for all captures.

    - Also, the number of frames captured by the TDA2 is one less than the number of frames sent by the AWR devices when the AWR devices are configured to send out a finite number of frames

    Please refer to mmwave_studio_release_notes.pdf (Section 3.1.1 Cascade Specific Limitations) that comes as a part of the mmWave Studio package :
