I don’t understand, what is the Turnaround Test? How to measure? What is he measuring?I have studied ch17 (JN-AN-1242), but I still don't understand.
Hi Daniel, I hope you're doing well!
The Turnaround RX-to-TX test measures the delay between the end of the received packet and the start of the sent ACK, and allows for the RF signals to be monitored with a Spectrum Analyzer.
These test modes are part of the PHY requirements of IEEE802.15.4.
Please let me know if you need any more information.
Take care, best regards,
