Re: [Discuss-gnuradio] About MIMO-cable

I am also interested in using the cable. We bought 10+ USRP2 and several MIMO cables, hoping to set up a MIMO network. But I have not figured out how to do that. I read through Josh's UHD MIMO announcement: http://old.nabble.com/UHD-Announcement---July-6th-2010-tt29091756.html#a29276686 But st

[Discuss-gnuradio] About the directionality of the LP0410 antenna.

Hi all, We hope to do some experiments with the LP0410 antenna. Before that, we hope to know more about its characteristics: 1. Is it a directional antenna? 2. If so, is there statistics about its directionality (e.g., beamwidth)? We did not find relevant information in its data sheet. Hope

Re: [Discuss-gnuradio] How to connect LP0410 to the daughter board?

Hi Matt, It seems that we need SMA-M to SMA-M cable to connect the WBX to LP0410. Will the SMA-SMA cable on the Ettus website work for this purpose? Thanks! Matt Ettus wrote: > > The connector should have been included. Send an email to sa...@ettus.com > with your order number and we'll

[Discuss-gnuradio] About clock rate of USRP E100

Hello list, We are planning to do some experiments with USRP E100. One advantage of E100 that we are excited with is that "The user can choose (at run time) a convenient clock rate". Our question is: 1) When we change the clock rate changed, is the main clock rate changed, or is it just change

Hi Philip, Thanks a lot for your kind help! >From the description here: http://elinux.org/OMAP_Power_Management#DVFS:_Dynamic_Voltage_and_Frequency_Scaling I see that it's possible to change the operating frequency of the OMAP using certain commands. Do you know if E100 supports such commands

Re: [Discuss-gnuradio] About clock rate of USRP E100

As far as I know, the decimation is after the ADC, so ADC rate doesn't change after changing the clock rate. I'm happy to be corrected if it's not so. :) Alexander Chemeris wrote: > > Hi, > > What about ADC/DAC clock rates? > > > -- > Regards, > Alexander Chemeris. > http://www.fairwaves.

Re: [Discuss-gnuradio] About clock rate of USRP E100

Hey Matt, Thanks a lot for your help. Could you explain how to slow down the FPGA/ADC rate? How should we modify the firmware? Which part of the code should we look into? Thanks! Matt Ettus wrote: > > > As it is currently set up, there are only 2 clock rates. The OMAP > processor can ru

Hi Josh, Thanks a lot for your help! We will try this after our E100 order arrives. Josh Blum-3 wrote: > > >> Thanks a lot for your help. Could you explain how to slow down the >> FPGA/ADC >> rate? How should we modify the firmware? Which part of the code should >> we >> look into? Thanks

e able to SSH into the E100 as root over Ethernet. Just make sure you give the E100 time to boot up before trying. Cheers, Ben > > Anyone who had experience with E100 please help! Thank you! > > Miok Wah wrote: > > Hello list, > > We got the USRP E100 and tried

[Discuss-gnuradio] Compiling GNURadio on openembedded for USRP E100.

Hello list, I compiled the uhd host code on USRP E100, and it took 2.5 hours. I guess compiling gnuradio directly will take 10x more times. So I am now trying to cross-compile it via open-embedded. It seems that openembedded already has the recipe for gnuradio. My question is: how to configur

Re: [Discuss-gnuradio] USRP E100 login: Ethernet and USB?

Hi Philip, I see. We used a powerless USB cable. That's very likely to be the reason why the PC doesn't recognize it. We'll try externally powered USB cable once we get one. Thank you for your help. Philip Balister wrote: > > On 01/27/2011 01:36 PM, Miok Wah wr
