RE: ADRV9002 Loopback Rx to Tx

Thread Summary

The user inquires about enabling a low latency Rx1 to Tx1 loopback in the JupiterSDR, noting it's not natively supported. The final answer suggests implementing a custom FDD repeater as described in the User Guide, with no specific configuration details provided. The accompanying answers do not offer additional critical information.

Hey all. Is there a way to enable this loopback in the JupiterSDR? As I understand, the Jupiter it is not compatible with TES and this loopback is not implemented natively. So, what is the best approach if I wanted to implement this loopback? I need a consistent Rx1 to Tx1 low latency loopback, basically the FDD repeater described in the User Guide.

  • 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?
