Hi Cinaed, thanks for your help.

Actually, it's up to date out of date OS unless you used backports but
then it may still be out of date.
I believe sid is Debian 6 and the current version of Debian is 8.
No, Debian sid is the bleeding-edge development version and it has
version 2015.07.2 of the HackRF software.
I tried to update firmware and cpld, but nothing changed.
Giovanni.

The HackRF is 8-bits and people have done similar with 8-bit rtl-sdr
dongles using a directional coupler and a noise source (
http://www.rtl-sdr.com/rtl-sdr-tutorial-measuring-filter-characteristics-and-antenna-vswr-with-an-rtl-sdr-and-noise-source/
), so I do not see why it would not work with the HackRF (in theory
anyhow). Using either https://github.com/polygon/sdr-power if the
bandwidth is more than 20MHz or just
sdr#/gqrx/CubicSDR/gnuradio/Pothos/osmocom_fft/... if it is less than 20MHz.

Okay thanks.
The git version of the HackRF firmware is a snapshot of the bleeding
edge at some point in time too.
You should post the output of
hackrf_info
Also, you need to test to see if your computer can sample at 8 MHz
without dropping data
hackrf_transfer -r /dev/null
by comparing the output of the 2 columns. See
https://greatscottgadgets.com/sdr
The rtl dongle samples somewhere around 2.5 MHz but typically less than
3 MHz.
The default sampling rate for the hackrf_transfer is 10 MHz.
And there's a DC offset at the center frequency - you need to look into
how the program deals with it.
I tried to update firmware and cpld, but nothing changed.
Giovanni.
