# Attenuation (dB) parameter in PlutoSDR Sink block

Hello, I noticed that in the PlutoSDR Sink block description in the following link: https://wiki.analog.com/resources/tools-software/linux-software/gnuradio is said that the range for the attenuation parameter is from 0 to -89.75 dB in 0.25dB steps. However in the attached reference image 10 dB is used. I'm quite confused because in gnuradio https://wiki.gnuradio.org/index.php/PlutoSDR_Sink is said that the range for the same parameter is from 0 to 89.75 dB in 0.25dB steps. So, What is the correct range that should I use? Thanks for the answer.
