osmosdr + bladerf I/Q data format.

Post by mranga » Thu Mar 10, 2016 3:09 pm

Hello,

I am new to bladeRF / osmosdr. I am using gnuradio to set up a processing pipeline. I'd like to know what format of data comes out of the source block (i.e. int, float32 etc.).
Thank you in advance.

Ranga.

Hi there,

When using the gr-osmosdr Osmocom Sink and Osmocom Source blocks, you will be working with complex floats in the range [-1.0, 1.0]. I would recommend keeping things at a max of [-0.95, 0.95] when you can, just to avoid clipping.

Best regards,
Jon
