[USRP-users] Re: HELP regarding B210 and B205mini-i
Dear sir, I am using B210 and B205mini-i. I have a few doubts. I hope you can help me. Doubts are listed below: 1) In matlab simulink there is an option of master clock rate, but no description can you please elaborate on that. Also it has some limit i.e., 56e6 Hz what happens if I use more than this limit. 2) Is there any relation to select center frequency, master clock rate, interpolation/decimation factor and gain. 3) Can you give the range of suitable gain. 4) There is an example in matlab for frequency calibration while using that when I plot the spectrum it's the same with or without antenna which suggest it is not working correctly. Can you suggest where the problem might be? 5) I am trying to send a simple QPSK signal and receive(example from matlab simulink). All blocks work fine in simulation but when I use USRP for Tx/Rx BER is always 0.5 and I think usrp is not detecting any signal. Is there any parameter mismatch?

[USRP-users] HELP regarding USRP N200
Respected sir, I am trying to connect multiple USRP N200 simultaneously to the same system to use in MATLAB. However, It is not recognized by the system. My PC has 2 ethernet ports (10 and 5 Gbit). N-200 connects via a 10Gbit port but not by 5 Gbit. I have changed the IP of N-200, but it doesn't work. I have tried to use a router to make a local LAN to connect the PC to 2 N-200, but it did not work either. Is there any specific way to connect multiple N-200 in the PC and use it in MATLAB for simultaneous operation?It will be very helpful for my experiment. -- *Thanks and Regards* *Arhum Ahmad* Ph.D. Scholar, Electrical Engineering Department, IIT Ropar +91- <+91-7015802356>7974897279 | arhum.19eez0...@iitrpr.ac.in <2016eez0...@iitrpr.ac.in> Lab No. 323, Communication Research Lab, J.C.Bose Building -- **CONFIDENTIALITY NOTICE: The contents of this email message and any attachments are intended solely for the addressee(s) and may contain confidential and/or privileged information and may be legally protected from disclosure.

[USRP-users] Re: HELP regarding USRP N200
Thank you for the response. Sir, both of my ports are "Gigabit Ethernet," so I was hoping two N200 might respond on ping in the windows command window since I have changed the IP of both N-200 to "192.168.10.1" and "192.168.10.2". Is there any way to connect multiple N-series in windows with my setting or a way to resolve the issue? If two USRP are recognized by PC, the rest is easy to use in MATLAB.

[USRP-users] Help Regarding Transmitting Gain of USRP N-200
Respected sir, I am using N-200 USRP for transmitting a signal. While transmitting, I have changed the Gain value in the SDRu transmitting block, but my signal strength at the receiver remains the same. I also stop and restart the code but the change in gain does not affect the received signal. I have tried the changing gain via both available options i.e., input port and dialog, but it seems to have no effect on the receiver. The signal strength at the receiver remains the same. I have tried 30 dB(Maximum gain) to 0 dB (minimum gain) in both cases received SNR is the same (i.e.,15 dB). I am using a wireless connection in line-of-sight, with minimum Tx gain at least a few drops in SNR should be observed. I have also tried -50dB (just checking) but no effect in the SNR is observed. The same thing I have tried using B210 as Tx, Rx signal strength does change in this case. However, while using N-200, no effect of changing the gain value is observed. Somehow gain value is fixed in N-200 while using the MATLAB SDRu block. Can you PLEASE HELP ME!!! IT IS VERY, VERY IMPORTANT. -- *Thanks and Regards* *Arhum Ahmad* Ph.D. Scholar, Electrical Engineering Department, IIT Ropar +91- <+91-7015802356>7974897279 | arhum.19eez0...@iitrpr.ac.in <2016eez0...@iitrpr.ac.in> Lab No. 323, Communication Research Lab, J.C.Bose Building -- **CONFIDENTIALITY NOTICE: The contents of this email message and any attachments are intended solely for the addressee(s) and may contain confidential and/or privileged information and may be legally protected from disclosure.
