Hallo everybody, I purchased the spectrum analizer n9000cxa on january and since first measurement of conducted emission I have experienced very high level of noise. The noise is about 47 dB starting at 150k, decreasing at about 25db in the 10-30 MHz. I checked the compensation values for transient limiter, lisn etc all seems ok. Tried with functuin generator and all gonne ok, but the noise is Steel here. I cannot use the results of measurement with this high noise level . Ang. Idea ? Thanks !
