I had no idea this was a thing, but it turns out to exist on the SB6183 (http://192.168.100.1:8080/), though doesn't support Firefox for some reason.

Huh. On my SB8200 this interface is up but doesn't send any data (Chrome normal and incognito).

If it's like my SB8600 model you can access the spectrum analyzer as a tab in the main interface, no need for a separate port.

Pssshst... That model supports custom firmware...
