The top-level question is, can gr-uhd support all the necessary N321-specific commands necessary to export the TX LO from RF0 to RF1? That would include running the command to set the 1x4 splitter. That's the one in question.Yeah, I'd say "after-init", and have it grab the object name of the usrp object? Using Pythonic, rather than C++ syntax?get_device()->get_tree()->access<bool>("mboards/0/dboards/A/tx_frontends/0/los/lo1/lo_distribution/LO_OUT_0/export").set(true)If not, Marcus suggested using a python snippet. I've used that with RFNoC before, but how would that work? I'm guessing it would be an "after-init" and then call the python API for the above (if that command is supported)?Thanks
Hi, In case it helps, in the GNU Radio testbed at the ATA (https://wiki.gnuradio.org/index.php/GR-ATA_Testbed) we're using self.uhd_usrp_source_0.set_lo_export_enabled(True, "lo1", 0) self.uhd_usrp_source_0.set_rx_lo_dist(True, "LO_OUT_0") self.uhd_usrp_source_0.set_rx_lo_dist(True, "LO_OUT_1") self.uhd_usrp_source_0.set_lo_source("external", "lo1", 0) self.uhd_usrp_source_0.set_lo_source("external", "lo1", 1) self.uhd_usrp_source_0.set_lo_source("external", "lo1", 2) self.uhd_usrp_source_0.set_lo_source("external", "lo1", 3) in a "Main - after init" Python snippet together with these patches: https://github.com/daniestevez/uhd/commit/0a6da1a3fd5839b862cac740ed702923ed21b096 https://github.com/daniestevez/gnuradio/commit/f9909bade86045f379f83001de27317cc261807fIf someone gets the 1x4 splitter going directly in Python, I would be interested in knowing how it's done, since that would save us from having to patch UHD and GNU Radio.
Best, Daniel.
