I think it’s possible you could use Python/pip to install the gnuradio package directly from your ssh session – just like installing any Python package?

I’m currently using a newly flashed a SD image (e3xx_e310_sg3_sdimg_default-v4.4.0.0-rc1). From a version check it shows that both UHD and GNU Radio is installed on my E310 image. But for some reason it doesn’t recognize the gnuradio-companion command on terminal. Is there something I need to make this work?

[USRP-users] Re: Sharing one UHD device across multiple hosts
Perhaps consider having a virtual machine (VM) act as the go-between? The VM talks directly to the device via UHD, but then provides its own API that splits out the streams/sessions to clients running elsewhere. You'd have to write some code, of course; but presumably you could implement something similar to UHD, so the clients would appear to be talking to the device directly, other than some home-brew way of selecting the device/session.

The USRP N2xx has an "alternative stream destination" API, but that did not make it into future USRPs as far as I know. ___ USRP-users mailing list -- usrp-users@lists.ettus.com To unsubscribe send an email to usrp-users-le...@lists.ettus.com ___ USRP-users mailing list -- usrp-users@lists.ettus.com To unsubscribe send an email to usrp-users-le...@lists.ettus.com
[USRP-users] Re: High power TX/RX same antenna
Can you just add more attenuation between the output of the circulator port that goes to the RX port on the N310?

I want to transmit 40 dBm using one antenna connected on both TX and RX ports. The best circulator I found has 18 dB isolation, which isn’t sufficient considering -15 dBm USRP max input power. What is the best approach to consider? Thanks a lot. Best regards, Charbel ___ USRP-users mailing list -- usrp-users@lists.ettus.com To unsubscribe send an email to usrp-users-le...@lists.ettus.com
