SM200A Relative amplitude accuracy.

Hello I have a question about the Accuracy of the SM200A.
I’ve seen that you are specifying total accuracy of the SM200A but I was wondering what the relative accuracy or linearity of it would be in sweep and real-time mode. Do you have any research on this?

Quadsat,

We do not specify relative amplitude accuracy, but as an FFT-based spectrum analyzer it is typically very good. After the device has warmed up for an hour, as long as you avoid switching bands which can add a tenth or two (dB) to the uncertainty, you should typically see a few hundredths of a dB relative amplitude accuracy until you approach DANL or the device changes temperature.
