You may want to consider obtaining an FCC experimental license. A new
category called the "Program Experimental License" has been created.

Hi,
For a setup where the tx-rx are indoors, can I assume that the USRPs transmit
power will not cause any significant interference to licensed users? I'm not
planning on using an amplifier, but I will be sweeping over a significant
portion of TV white space. The room doesn't have RF specific
Howdy,
I just managed to accidentally reproduce this exact error. Any updates please?
Thanks,

Hi Jose,
IIRC, the B210 can use up to ~800 mA and the GPSDO has a max of ~200 mA.
Assuming the 2 USB 3.0 ports each supply 900 mA, it should work. Check the
specs on the host system to make sure each port can deliver enough power.
Some controllers limit the total power across ports.

Mic
Hi Jon,
There are 2 cable kits available. One is 4" and the other is 24". They

Hi Jonathon,
Thank you for the hint. Actually your suggestion was the first thing I
tried but it didn't work. It threw the error:

Hi Tarik,
I'm glad you got that working. Yes, modifying UHD is certainly a way that
you can specify a custom file. I didn't mention it because the device
arguments method works in nearly all software. For instance, the path to
the bitstream can certainly be supplied as a parameter in GNU Radio

Hello Derek,
I managed to specify custom bistream file by editing one of uhd source files (
“/rfnoc/src/uhd/host/build/lib/transport/nirio/lvbitx/x310_lvbitx.cpp”)
Changing line 50 to
std::string fpga_file = “usrp_x310_fpga_RFNOC_” + option + “.lvbitx”;
and then calling in folder “/rfnoc/src/uhd
Hi Tarik,
The USRP source in GNU Radio has a spot for specifying device arguments.
The osmocom_fft application has a "--args" option the same as the UHD
utilities. There is not currently the ability to specify a custom default
FPGA image but it is a feature we agree would be useful.
Regards,
Dere

Hello Derek,
I got you. Thank you.
I have one more question, where can I specify default bit stream location?
What happen now is that by calling
uhd_usrp_probe –args =”fpga=/path/to/image.lvbitx”
I am able to flash USRP with RFNoC design. However, after I run gnuradio
fosphor program it again
Hi Tarik,
Your steps are based on the misunderstanding of how the image loading
occurs in each of these scenarios.
When using PCIe the FPGA will always be reloaded from the host computer.
Every program you run using the PCIe link needs the
"fpga=/path/to/image.lvbitx" string added to the device a
Hello Martin,
I hope I am replying now correctly (I am using reply all to you and mailing
list).
I am still not able to flash RFNoC bit stream on FPGA. Here is what I am doing:
1. First step - Check status of device
Call: uhd_usrp_probe
