IWR6843AOPEVM: High_accuracy demo only support TX1 antenna?

Shine

Part Number: IWR6843AOPEVM

Hello Champs，

Does the High_accuracy demo in C:\ti\mmwave_industrial_toolbox_4_7_0\labs\level_sensing\68xx_high_accuracy support other TX antenna e.g TX2, TX3? Customer changed the TX number in channelCfg 1 2 0 in high_accuracy_demo_68xx.cfg file? But the demo doesn't work anymore.

If he changed the Rx antenna number to 2, 4, 8 in channelCfg, it can work with RX2, RX3. It is curious why the TX2, TX3 can't work. Does the demo only support TX1?

Thanks.

Hi Shine

I can confirm that only Tx1 is allowed for standard demo operation. If different Tx are desired then they will need to be specified in c code.

Hi AG,

Could you tell me where to change different TX in the c code? I looked through the code and can't find the definition for different TX antenna.

Thanks.
