Thank you. That's fine; I don't really need to resolve down to individual hertz even. Tens, or even as much as ~100 Hz resolution would probably be fine for my purposes.

Thank you! By the way, is this documented anywhere (I might have to give a source at some point)? https://files.ettus.com/manual/page_general.html#general_tuning Then there's the source-code for the relevant FPGA image... Keep in mind that very-fine tuning resolution doesn't really get you very far when the system reference clock produces much more uncertainty than your tuning step. The on-board clock on the N210 is (AFAIR) 2.5PPM. So, sub-1Hz resolution isn't terribly meaningful...

Even though individual daughter cards will have a synthesizer resolution much larger than that, the tuning code uses that knowledge and programming of the DDC / DUC to deliver subHz resolution.

By tuning resolution I mean, basically, the step size when selecting center frequency. I have been looking over the Devices & Usage Manual<https://files.ettus.com/manual/page_devices.html>, but have not been able to find an answer.
