[USRP-users] Here's how to get the N321's LO sharing to work in GNURadio 3.9 with UHD4.1.0.5

2022-01-28 Thread Paul Atreides
Currently there's no way to use LO sharing with the N321 in gr-uhd. The N321 uses an RF Distribution board which has port terminations that need to be switched to active outputs when the LO is exported. This isn't accessible in gr-uhd. In order to access the LO distribution enable commands shown h

I just noticed that you are using "second_addr". My suggestion is to avoid this unless you need it. A single 10Gbe can handle up to about 250 MS/s aggregate. So, in your case, one 10Gbe link is sufficient. Rob On Fri, Jan 28, 2022 at 10:05 AM Marcus D. Leech wrote: > On 2022-01-28 05:53, seckin

Hi, The line "EN_FFT_SHIFT: 1" needs to be indented. It's supposed to be part of the "parameters:" block. If you have jsonschema installed then the error messages are a bit more useful: "Additional properties are not allowed ('EN_FFT_SHIFT' was unexpected)" Thanks, Wade On Fri, Jan 28, 2022 a
