I thought that timed tune commands do not work — I need a queue of timed commands. I looked at the HDL for RFSoC and it appears the DDC in the ADC/DAC hard block does not have an external frequency control enabled. How are timed tune requests implemented without this feature?
---------- Claude says: ------------- The Ettus USRP X440 lacks support for timed tuning on the RFSoC Numerically Controlled Oscillator (NCO). While commands are queued in the FPGA FIFO, timed frequency tuning cannot be executed. Below are the key constraints for handling timed commands and command queues on this device Key Command Queue & Timing Constraints * Timed Tuning Limitation: The X440 relies on direct-sampling of ADCs/DACs; timed tuning of the internal RFSoC NCO is not supported. --------- ________________________________ From: Jurk, Dennis <[email protected]> Sent: Wednesday, June 17, 2026 3:14 AM To: Eugene Grayver <[email protected]>; usrp-users <[email protected]> Subject: [EXTERNAL] AW: X440 timed commands for tuning Do not open links or attachments unless you recognize the sender. If unsure, click the Report Phish button or forward the email to OPSEC. Hello Eugene, timed commands are supported on the X440. Set the command time with set_command_time and then send the commands (set_rx_freq or set_tx_freq for freq tuning).

The RFSoC definitely allows using FPGA (PL) logic to trigger cross-tile configurations. Eugene Grayver, Ph.D. Principal Engineer 310-336-1274
