Re: [Discuss-gnuradio] Overflow error even at lower sampling rates

[john jade]

Hi Marcus,

I am not getting overflow,when i use uhd_fft. Can you please tell me what might be the problem.

Thanks.

Hi,

I am getting overflow error ,even at low sampling rates.I am using USRP N210 device.If the sampling rate is less than 5MHz then there is no error.I know that USRP N210 can support at Max 25MHz.Can you please tell me what might be the problem?

I just connected UHD source block to FFT sink in my example.

My system specifications.

OS :Ubuntu 12.10
processor :Intel  Core i5-3570 CPU @ 3.40GHz × 4
RAM 4GB

I am using 1Gbit Ethernet card.


Thanks

Overruns are caused by your computer not being able to "keep up" in real time with the dataflow from the USRP.

What happens if you use "uhd_fft" at the sames rates you're getting overflow with in your simple flow-graph?
