Hi ,

i had raw data of my standard unit and DUT. and i would like to check the lineaerity of my DUT.

i test at one fix frequency and different power level.
how do i calculate or plot the linearity of the data?

My data example :

Standard unit DUT
at -10dBm  standard = -21.72dBm  dut = -21.65dBm
at -9dBm standard = -20.71dBm dut =-20.62dBm
at -8dBm standard = -19.71dBm dut =-19.60dBm
