Hi John,
Broadcast masks were introduced into Spike under the Spectrum emission mask measurements awhile back (analysis mode drop down menu). For the SA44B, you may need to disable the outermost ranges (the ones that are > -80dB down) as the SA44B doesn’t have the dynamic range to measure these ranges. The noise floor will trip it. That being said you will still be able to visualize the ranges.
If you have any questions as you start working with this measurement, please let us know.
Regards,
Andrew
