Hi everyone,
i'm working with the ADRV9009-ZU11EG, i tried to generate a SinWave signal with a -35dBm power with a signal generator. I tried to measure this SinWave at 2.4GHz and 5.8GHz by means of power density spectrum computation. At 2.4GHz i found the signal magnitude which is correct regarding the generated signal. But at 5.8GHz i measure a signal level much lower than what expected (about 10dB lower). I would like to know why? and is there any solution to this issue?
Find bellow the measure power with the ADR9009 with 8 channels.
| 2,4GHz (dBm) | 5,8Ghz(dBm) | |
| CH 0 | -35 | -45 |
| CH 1 | -35 | -42,9 |
| CH 2 | -35 | -40 |
| CH 3 | -35 | -50 |
| CH 4 | -35 | -45 |
| CH 5 | -35 | -44 |
| CH 6 | -35 | -45 |
| CH 7 | -35 | -48 |
An example of time domain and frequency domaine signal mesured at 2.4GHz.
An example of time domain and frequency domaine signal mesured at 5.8GHz.
