    Hello,

    dBm/Hz = dBm – 10*log10(RBW)
    Is this formula works well for all types of RBW windows (flattop, nutall, gaussian) for BB60C device?

    It would be great if you add dBm/Hz to Spike (at least for markers) and I could get noise measurements directly in your software.

    Regards, Ivan

    Ivan,
    That formula is quite accurate for flat top windows, but may be a fraction of a dB off for nutall and gaussian, due to the RBW shape.
