There's also a balun on the AD9361 input. Unfortunately, the balun part number for the low frequency path is not on the schematic. Ron On 02/01/2018 05:39 PM, Dan CaJacob via USRP-users wrote: That's an interesting thought. The 9361 does have a pretty bad match. I'll try adding a 50 Ohm

That's an interesting thought. The 9361 does have a pretty bad match. I'll try adding a 50 Ohm attenuator and see if that helps. On Thu, Feb 1, 2018 at 5:14 PM Robin Coxe wrote: > Hi Dan. Both the B200 and the E312 use the Analog Devices AD9361 RF > integrated

2018-02-01 Thread Ron Economos via USRP-users
I think the incompatibility issues folks have are due to trying to use gr-uhd (a component in GNU Radio) that was built against a certain version of UHD with a different version of UHD. If you're building from source, you should be able to use pretty much any recent version of UHD with any

Hi Dan. Both the B200 and the E312 use the Analog Devices AD9361 RF integrated transceiver. This chip does have an integrated LNA. Perhaps there's some sort of mismatch between your DUTs and this integrated LNA at <1 GHz? ADI publishes the RX S-parameters:

Thanks for the announcement of the new UHD 3.10.3 release. I've noticed on the gnuradio mailing list some comments about possible incompatibility of certain UHD versions and Gnuradio versions (assuming I'm reading things correctly). Is there a table that lists compatibility of the various UHD

You could see this if you're outputting one data type from uhd_rx_cfile and reading samples as a different data type in Matlab. On 02/01/2018 11:38 AM, Yeswanth via USRP-users wrote: Hello Everyone, I am new to using USRP . I am capturing samples on a CBX board using “Uhd_rx_cfile -A “TX/RX”
