Please can you advise a customer's query ...
.... Where's the specification on phase offset for the AD9371 in the Docs, menus or App (API) ?
Thanks and Regards,
Not sure what you are looking for when you say "phase offset". Can you explain a bit more ?
Datasheet has details on LO phase noise (integrated and spot) and deviation from linear phase across the Tx and Orx bandwidth.
Image rejection details are also available in datasheet.

In the AD9361, there is a phase offset and correction function see UG-570 rev.0, page 12, and UG-671 rev.0 table 32. Similarly, Is there no phase offset for the AD9371, menus or App (API) ?
for AD9361 we provided reg map and Table 32 is the register where the calibration values are stored by QEC calibration machine.
For AD9371 we provide API and this is taken care by QEC calibration running in ARM firmware, is not exposed outside.
Thanks for the info. at least we are aligned. So how does one know what the offset calibration is, at least this should be able to report it.. is there a register in the API where this can be quizzed ?
The C API is pretty fixed for the foreseeable future, and the register map is not provided publicly. Is there a reason you need this number?
