Hi everyone.
I downloaded the Wideband Spectrum Analysis example and tried it, but it shows no spectrum.
http://www.ni.com/white-paper/13882/en
Configuration:
Anritsu Vector Signal Generator MG3700A==> NI USRP2920 (connected to Windows7 PC)
Freq. 10--50MHz
Power 0dBm
Is there any suggestion?
Solved! Go to Solution.

Hi.
I have read your suggestion and I did experiment with the different parameters. But the trouble has not been solved. The snapshot is attached, and the error out message is as follows.
Is there any suggestion?

Hi Walrus 1125,
What version of the driver are you using? I'm guessing that you are using version 1.0. I looked in the subset RxHWParameters.vi block diagram property nodes since that is where the error message indicates the error is coming from. There is a call to the Active Channel property. This property is new to the NI-USRP 1.1 driver. Updating the driver should clear this error.
You can find the 1.1 driver here.
After you update the driver, you will also need to update the firmware and FPGA image. Here is a KB that explains how to do this.
Let me know if this doesn't fix the problem, I'd be happy to help.

Hi Sarah,
I was using NI-USRP 1.0 driver. So, I updated it to version 1.1, and also updated the firmware and FPGA image.
Your advice solved my problems.
Thanks a lot.
Best regards,

All of the new examples (e.g. http://bit.ly/usrpMIMOExample) posted on the example community require the NI USRP 1.1 driver. Unfortunately, some of the new examples were posted before the driver was released publicly. As Sarah mentioned above, the 1.1 driver is available now, so there shouldn't be too many more concerns. Sorry about any confusion.

I noticed that the link I gave in my previous response no longer works and points to a dead cartoon fish. You can click it if you'd like to see the fish, or you can go to https://decibel.ni.com/content/groups/ni-usrp-example-labview-vis to actually get to some examples.

Hi everybody.
I downloaded the Wide band Spectrum Analysis example as my project is to make spectrum scan for certain area I tried it , but there is a problem that it may be an obstacle in my project .
http://www.ni.com/white-paper/13882/en
the software is: labview 2015
the hardware is:USRP2932
-connecting the laptop to the usrp2932 and inserting the suitable parameters ,the problem is that when I make the scan there are many discontinuities along all the band ,any one can give me an answer for this problem and how I can solve this problem ,there is an screenshot for my code.
