Wide spectrum

AV

Thu, Aug 18, 2022 2:18 PM

Dear all,
I am trying to acquire a “wide” spectrum with the B200 and B200 mini. For wide I mean wider than the bandwidth of the board, and therefore some way of fast multiple acquisitions with “frequency hopping” and “stitching”.
Do you have a good solution to recommend? I tried soapy_power (which seems working but it is not maintained) and GNURadio (with it, I did not manage to have a “fast frequency hopping”, and therefore the acquisition is very time consuming, with several seconds delay at each tuning).

Thanks and best regards,

Andrea

How fast do you need to go?  The B2xx chip, the AD9361 isn't known for
its ability to rapidly tune at timescales below about
  100ms.

Dear Marcus,

Thanks for your reply.

To put some numbers into perspective:
I am looking at acquiring something in the order of 300 MHz of LTE spectrum (about 6 times the bandwidth of the B200. Even if I think to use half of the bandwidth, that brings the factor to 12).
I would like to repeat the measurement at least 5-10 times, to be able to have an estimation of the variability of the signal. Of course, this opens a whole pandora vase on the combined effect of: duration of the measurement, syncing of the measurement rate with the signal and so on, leading to the fact that is possible to miss signals if they are rare and in short bursts (typica of LTE)… but let’s park this issue for the moment.

Taking the limit you mentioned and doubling it to stay conservative, I should be able to acquire the 120 spectrums in 120*0.2=2.4 seconds… that is way faster than what I was hoping!

When I used GNURadio, I created a script that run at a specific central frequency, saving the data on a file, called the script recursively with different central frequencies, and then loaded and “stitched” the data. The most consuming time, was possibly the saving-loading procedure.

I did expect that for such a “standard” application (acquire a wideband signal) there was something ready made in GNURadio, but could not find it.
As said, soapy_power does exactly this, but being not actively developed, I was hoping in finding something else…

Thanks and regards,

Andrea

By "calling the script recursively" I assume you mean iteratively? So
re-starting the entire Gnu Radio framework every time?

With stream tags, you should be able to know precisely which samples go
with which frequency, and use that to direct your logging.
