The MHO900 is the faster sibling of the DHO: 4 GSa/s, 50 Ω inputs and two built-in generators on the same RK3399 platform. NovaOS runs it with the same engine, UI and update system as the DHO, with each model's real hardware limits in its own table.
The MHO934, MHO954 and MHO984 share one platform. NovaOS drives its acquisition FPGA, configured from a file at every boot, its LMK04826 clock and its 16-core interleaved ADC directly.
Developed and measured on an MHO934. Other MHO900 models will be confirmed on real hardware before we list them as supported.
| What | Stock | NovaOS |
|---|---|---|
| Operating system | Android 7.1, Linux 4.4 | Linux 6.12.112, Yocto, systemd, Rust |
| Boot to a live trace | being measured the same way | 11.9 s from kernel start (later boots) |
| FPGA power-on wait | a fixed 500 ms | 24 ms, watching the FPGA's own INIT_B |
| ADC interleave spurs, 2 GSa/s | 2.3 to 8.1 mVpk without a self-calibration, varying from boot to boot (four boots) | 0.5 to 1.2 mVpk after self-calibration, kept across updates |
The MHO900 threads are mostly about options and bandwidth codes. NovaOS isn't that: no option codes, no licence files, no patches to Rigol's software. It is a separate operating system with its own engine, so the hardware's real limits are the only limits, and every model is described by its own table of those limits.
NovaOS runs our MHO934 every day, including streaming its screen to a wall panel. It isn't available to download yet. Tell us which MHO you have and what you want from it: [email protected].
