Spec reality check: CLAIMED 100 MHz / 1 GSa/s: community measurements put usable analog bandwidth far below the claim (EEVblog's multi-thousand-post thread puts '100MHz' in scare quotes; Elektor found sibling models 'stretched'). Treat as a ~25-30 MHz instrument.

Which one do I buy?
vs a used DS1054Z or new DHO802: both are real scopes with honest specs for not much more. The 1013D's argument is the tablet form factor, not the numbers.

Gotchas to know
- The headline specs are not real (see accuracy note) — plan around ~1/4 of the claimed bandwidth.
- 8-bit, limited triggering, no protocol decode worth the name.
- FNIRSI ships new SKUs constantly; each gets its own 'real specs?' EEVblog thread — check before buying any of them.
