NovaOS, our own operating system, runs on both: here are the Rigol MHO900 and the Owon ADS800A as NovaOS sees them, on the units we own, an MHO934 and an ADS802A.
These are NovaOS's figures, on our own units, with our own software. Every figure here is NovaOS running on the units we own, dated, and shown only when both were measured the same way within a day of this page's build (2026-10-17). NovaOS is in active development: these figures, and how much of each scope's hardware NovaOS uses, will change as we keep optimising it and find how to get the most out of the hardware. They are not a verdict on any maker's hardware, or on its own firmware. NovaOS is independent software, not made or endorsed by Rigol or Owon.
The unit NovaOS runs on in each family, from NovaOS's own hardware table: the limits NovaOS works to on that model, with no software option tier in between. The last rows are where NovaOS stands on each.

From NovaOS's own hardware table, except where a data sheet page is named. Other models in a family can differ in channels, bandwidth and generator: the MHO900 page and the ADS800A page list them.
Each family's own user guide, checked feature by feature against NovaOS on that family. The guides differ, so the totals are not one list; each column counts its own maker's.

MHO900: the 313 features of Rigol's MHO900 User Guide; ADS800A: not yet checked feature by feature. Feature by feature for the Rigol scopes: compatibility.
Not yet measured. Nothing has been measured the same way on both within a day of this page's build (2026-10-17), so this page compares no figures yet; it shows them as soon as both are.
What NovaOS has measured on each, with dates, methods and raw data: NovaOS vs stock on the MHO900 (2 figures from the last day) and NovaOS vs stock on the ADS800A (none from the last day).
