If power decreases as frequency increases, then voltage or current must have also been affected. Then we should be able to use voltage to measure frequency response, so why are you refering to power? I don't understand this! | |

Even in a proper;y calibrated generator, you can expect the usable maximum power to decrease as the frequency increases. | |
| Oct 18, 2021 at 11:12 | comment | added | Valdi | If I understand correctly then for a generator, it is the ratio of power of the signal I want to generate, to the power of the generated signal versus frequency. But, the generator will ouput a signal identical to the one requested for the same frequencies, or not? So the power will not be different, or am I missing something? I also never heard of power used in frequency response analysis, do you have any reading material on that? | |
