RE: ADRV9002 Loopback Rx to Tx

Hello,

Jupiter SDR does not include internal cross-connects for loopback. Here you can find the HDL documentation: Jupiter SDR HDL Reference Design — System Level Documentation documentation.

For implementing this, checkout out the instructions and limitations in the  FDD Type Repeater Application Using Internal Loopbacks section of the ADRV9001 User Guide.

You can modify the HDL design by adding a simple AXI‑Stream passthrough block that forwards Rx1 samples to Tx1.

Regarding the TES support, I don't think it is compatible.

Kind regards,

Stanca

Hey all, thank you for the response.

I not an expert in this and have been trying to connect the AXI-stream from the Rx to Tx but it looks like the Rx does not have a nativeAXI-stream and won't connect to the Tx, which is. I am working on getting some kind of block to connect them but if such a block already exists, that would be very helpful.

I primarily got the Jupiter because the adrv9002 Rx-to-Tx loopback looked easy to implement through the TES. So, it is a little disappointing it is not compatible with TES, although I am sure there is a good reason.

Can you help me understand if there is a Rx-to-Tx loopback built into the transceiver that can be configured internally and if that is different from the HDL approach above?
