Thanks

I am also having difficulty setting up the limit lines.
For example in the attached screenshot I have used -67dB to generate a 40dB limit line. I see that the Limit Line points are specified as ‘dBm’ but what does that mean? If it means dB relative to 1mV then I would subtract 60 to convert from dBuV to dBmV (40dBuV would become -20dBmV). How does 40dBuV/m convert to -67dBm ?
