    I set 10 dBm for output signal @ 2.5 GHz by Signal generator (Agilent E4438C), however my spectrum analyzer shows up the level of above 15 dBm. I already tried to adjust Reference level and RBW/VBW but it happens to be like not any right sense. Could anybody know it ? please leave an explaination.
    Thank you,

    ALC is OFF , try with ON .. Signal Generator may have a calibration error or both..
