BladeRF 2.0 micro xA9 as spectrum scanner

Post by zbroyar »

Hi all,

Did anybody try to use bladeRF 2.0 micro xA9 as a spectrum scanner?

From whats I see it looks like a bad idea: after setting bandwidth and sps to 29.65 MHz and 59.30 Msps respectively it takes ~0.012 secs to execute bladerf_set_frequency(...), which yields ~3.12 seconds to cover available frequencies range of 70-6000MHz in 200 steps.

And it's without reading actual data :-(

Is there any chance I'm doing something wrong and it could work faster?

Thank you in advance :-)

The bladeRF 2.0 micro also has fast locking profiles, so it may even be faster than that! There is no limit why the on-board AD9361 couldn't go so fast, just needs software to drive it.
