Re: [USRP-users] N310 and gpsdo strange behavior

One more small thing The device arguments "time_source" and "clock_source" are not listed in the device arguments table in the UHD manual ( http://files.ettus.com/manual/page_usrp_n3xx.html#n3xx_usage_device_args). They are, however, shown as examples in the clock/time synchronization section (

[USRP-users] N310 and gpsdo strange behavior

I am learning to use the gpsdo capability of the N310 and I stumbled upon something strange. I have a capability in my software for displaying a message every time the "last PPS" value changes. Note that during startup, I set the clock to zero on a PPS trigger. If I set "time_source=internal,clock

Hi Ayaz, This is a USRP question rather than a GNU Radio one so I've copied your message over to the other list. If you're not a member of the usrp-users mailing list you should join that so you can see the responses. It looks like you have BasicRX and BasicTX daugtherboards installed, is that co

I am getting the error message below when I call the function get_mboard_sensor with the string "get_gps_sky_sensor". Actually, this just happened to be the first sensor name returned from the function get_mboard_sensor_names(). Below you will find my source code snippet, and then the error messa

[USRP-users] B210 TDD switching high DC

Dear usrp-community, We are developing LTE system based on B210, where TDD is of main concern. The problem is the high transient when switching from RX to TX. We observe pretty high DC during the TX frame, but what is even more obvious and also severe is the DC decay after switch back to RX. It

[USRP-users] UHD API

Hello all, I am working on a custom RFNoC based signal generator module on the X310 using UBX daughterboards. I have created a custom signal generator NoC block, that generates IQ samples based on register values and loaded this block together with a DUC NoC block on a X310 RFNoC image. I wish
