Hello, I noticed that in the PlutoSDR Sink block description in the website is said that the range for the parameter "Attenuation (dB)" is from 0 to -89.75 dB in 0.25dB steps but in the attached reference image (also in the website) 10 dB is used. At the same time GNU Radio describes the same parameter and stablishes the range from 0 to 89.75 dB in 0.25dB steps. So, What is the correct range to use for that parameter? The negative range or the positive range? Thanks in advance.
