AWR2944EVM: 4Tx & Phase Shifter unavailability issue in mmWave Studio

Part Number: AWR2944EVM
Other Parts Discussed in Thread: AWR2944

Hello, 

There is an issue that 4Tx & Phase Shifter cannot be used in mmWave Studio.

- My tool installation environment is as follows: mmwave_mcuplus_sdk_04_05_00_02 / mmwave_studio_03_01_01_00

- My HW configuration is as follows: AWR2944 EVM, DCA1000 EVM

In the SensorConfig tab of mmWave Studio, I set the following:

1. However, Tx3 cannot be displayed in the ChirpManager and ProManaget windows. There are only Tx0 to Tx2.

2. And in Phase Shifter, I set Tx0 0 deg., Tx1 90 deg., Tx2 180 deg. and Tx3 270 deg., but it doesn't seem to work.

The spectrum when set like that is as follows.

Please tell me how to solve this problem.
Thanks

    It is a known issue in the studio. But, with the manual 'set' button you will still be able to configure the chirp as you want.

    This heatmap shows you distance vs velocity comparison for non-static/moving things. If the device is static and there is nothing moving in front of it, then you won't be able to see any deviation in the heatmap.

    Hi Anirban,

    Thank you for your reply..

    It is a known issue in the studio. But, with the manual 'set' button you will still be able to configure the chirp as you want.

    -> Where is  manual 'set' button?

    SensorConfig -> Sensor Configuration -> Profile -> 'Set' Button?

    or

    SensorConfig -> Sensor Configuration -> Chirp -> 'Set' Button?

    I don't think you mentioned those buttons.
    Can you tell me what the 'Settings' button is?

    Thanks

    Hi SungHoon,

    Yes, I'm talking about exactly those buttons. Put your desired values in all the parameters and then click 'Set'.

    For example a chirp configuration - 

    • Profile Id - 0
    • Start chirp - 0
    • End chirp - 0
    • Start freq var - 200
    • Freq slope var - 50
    • Idle time var - 2
    • Adc start time var - 0.5
    • Tx en for current chirp - Tx3
    • Now click 'Set', it will create one chirp with index 0
    • Or you can create multiple chirps with same config by putting start index <your_start_index> and end index <your_end_index> 

    You can create upto 4 profiles(0-3) and 512 chirps(0-511) in the studio and you can check them in list format in corresponding 'Manage Profile' or 'Manage Chirps' section. 

    Thanks,
    Anirban

    Hi Anirban,

    Thank you for your reply..

    I set Profile 0~3 as follows.

    Then I clicked ‘Manage Profile’.

    1. However, Tx3 does not appear in ‘Manage Profile’.

    2. When I press the ‘Activate’ button, the following error occurs.

    3. When I click the 'Set' button and open the 'Manage Chirps' in the 'Chirp' frame, I still do not see the Tx3 settings (Only Tx0~Tx2)..

    4. And when I click 'Activate' in the 'Manage Chirps' window, I still get the error same as 'Manage Profile' window.

    5. I checked the chirp information of the acquisition data from DCA1000, but Tx3 information is still invisible. And 'Phase Shifter' is also not applied.

     

    Thanks,

    Jason

    Hi Jason,

    In the 'Manage Profile' or 'Manage Chirps' sections you won't see TX3 and the activate button doesn't work - these are some of the known issues in the studio. Please ignore using 'Manage Profile' or 'Manage Chirps' sections, you can check the list but don't try to activate the profiles or chirps from there.

    Configure the profile and chirps and then just hit "Set" button, that will do your job.

    Profiles are a type of template for chirps. One or more chirps can inherit the properties/parameter values from the corresponding profile. While creating a chirp, you select a profile id right? That particular chirp will inherit all the properties like - start freq, idle time, freq slope const, etc from that profile. So, creating multiple profile won't do much rather creating just templates.

    Here I can see you have only one chirp in the chirp manager, so all the chirps that you transmit will be of this type. That means all these transmitting chirps will inherit its properties from 0th profile only. If you want different chirps, then in the chirp configuration section create 4 chirps(with start and end index - 0,1,2,3 and profile id should also be changed accordingly). Then those 4 chirps will inherit from 4 different profiles.

    Thanks,
