I think the specs are preliminary. The 20MPts memory depth on all channels is interesting (Keysight doesn't even come close to that) and Tek finally put a display with a decent resolution in a low-end scope but what is missing are detailed specs like FFT length and decoding options. Without decoding this scope is just too expensive and also not very suitable for modern education.
I think education is what this thing was actually designed for. There seems to be a huge emphasis on the built-in "courseware" (which seems to be much more explanatory than the usual built-in help) and integration into Tek's classroom system.
This would also explain why it comes with Tek's TekVPI probe connector system, which doesn't make much sense for a conventional entry-level scope (too expensive).
I do like the LXI control screen.
I hope it works without Java
The overall scope properties remind me a lot of OWON. Tek already rebadges one of OWON's AWG series, and while this scope doesn't seem to have a direct OWON equivalent I wouldn't be surprised if this is in fact produced by OWON as a (heavily altered) OEM variant.
I doubt Tek sees this scope as a competitor to Rigol's DS1000z/DS2000/DS4000 Series, or the GW Instek GDS-2000E or the Keysight DSO-X2000, scopes which attract hobbyists and small businesses. The new TBS2000 seems to be designed particularly for that one market where Tek still makes a lot of sales - education.
