1db compression
If you look at the data below I put an input signal in and record the output and then calculate the change. So I basically expect to see a change in 1 dB if I change the input by 1 dB.
At which point would the 1dB compression point be? At -19 dBm? I'm not sure what the margin is in determining 1dB compression. Could it be at -25 dB?
Input (dBm) Output (dBm) Change (dB)
-30 -16.45 0
-29 -15.43 1.02
-28 -14.42 1.01
-27 -13.51 0.91
-26 -12.60 0.91
-25 -11.77 0.83
-24 -10.96 0.81
-23 -10.42 0.54
-22 -10.15 0.27
-21 -9.900 0.25
-20 -9.780 0.12
-19
Thanks for the help.
