Hi, On page 7 of the UBX-160 schematics https://files.ettus.com/schematics/ubx/UBX-160_revE.pdf there is a LO filter selection with three paths: - 800 MHz-2.2 GHz - passthrough (no filter) - lowpass 400 MHz..800 MHz Next to that, there is also a way to measure the LO on J3.
Question: - Is this LO filter automatically selected, and where should I look for the rules ? - Is there some way to control this LO filter selection via UHD, similar to a tune request? - The IQ mixer ADL5371 documentation warns that the LO's 3rd harmonic needs to be well suppressed. Is there benefit to be gained by using an external, more filtered LO instead of the on-board UBX-160 LO plus its filters ?
