Re: [Discuss-gnuradio] Frequency sweep using GNU radio

[Marcus Müller]

Hi Abhilash,

It's rather unusual to sweep in such little steps, considering your SDRs can deliver much higher bandwidth with no performance degradation (assuming you don't use a USRP with an adjustable analog bandwidth).

There's multiple approaches to sending bursts with USRPs at different frequencies, and the semantics are different for other SDR devices such as the BladeRF; hence, a general answer can't be given, I think.

It would be nice to specify fully which USRP you're planning to use, what the purpose of this scanning is, how fast you need to scan, how long you need to linger on one frequency.

Generally, give as much background as sensible when explaining a problem!

Best regards,

Marcus

Dear all,

I am new to GNU radio. I use bladeRF/USRP as the SDR. I want to send some signal/samples at frequency range 2.4-2.8MHz sweeping the band every 1MHz. 

I found a tutorial which says to use a slider. I want to know is there a way to frequency sweep without using sliders.

Can anybody help me how to achieve this?
