Hi Guys,
When I measured a sine wave with spectrum analyzer. I am curious that the reference level impacts the harmonics. For ref level = 0 dBm, SFDR ≈ 72 dBc. For ref level = 10 dBm, SFDR ≈ 81 dB. I thought the reference level is used to adjust the display only. I am reading a few documents of Agilent about spectrum analyzer. However, I have not find the answer until now. Would you please comments this phenomina?
Best Regards, Yawei
