That's absolutely missing the point. EMC/EMI testing is expensive, time consuming and requires scheduling and experiment design.

Being able to do local soft-run testing on-site to be sure that you eliminate the easy 90% of issues before you get to the lab would be a huge win.

I think that for a single device, this probably wouldn't help much over just having a more traditional signal analyzer, either benchtop or handheld. If you know what you're testing, just using a signal analyzer around it will give you a good first pass picture of emissions, and probably be much more informative and precise than this.

This seems more useful for finding unknown or hidden RF sources, for instance looking thorugh an entire building to find unknown RF sources, or maybe a whole complex assembly like a car or aircraft.

It is surreal to me that a comment stating that being able to do a certification pre-check on site before booking testing got downvoted.

Sure, maybe this isn't the device for that... but the idea that what I said was objectionable is just bizarre.
