Great video! I put out one on the same subject a couple months back using an Aeroflex 7100 to take the measurements, but using a network analyzer as you did is the "proper" way to take this measurement. 😁👍
Just to clarify the P1dB is the input signal level (in this case it P1dB = -10 dBm) and the Output OP1dB is the output power OP1dB = P1dB + Gain = -10+18=8dBm
As I understood, he's talking with the output value for the compression point. -8 dBm is the output (input+gain). and I think it is reasonable because it is the amount of output power that determines the 1dB compression point.
Thank you so much
I actually have an exam where this is being questioned soon and this really helped me :)

Why is the 18db gain added to the input power to get the 1db point? Wouldn't it be the input (-10dbm) value we want?

When amplifier is in compression, will it create distortion/harmonics?
Excellent
10:20 your diagram would've been perfect if you had put -10dBm as input instead of 0dBm. Because at 0dBm the ideal output is 20dBm and not 10dBm.
Thanks!

THat looked like the 0.75 dB compression point to me...
