The scope that made 12-bit affordable: four channels, a genuinely good touch UI and USB-C power for the price of yesterday's 8-bit entry scopes. The community firmware unlock made it the default first 'real' scope of the mid-2020s.

Which one do I buy?
DHO802 = same scope, 2 channels. DHO812/814 = 100 MHz versions. DHO914S adds MSO, AWG and Bode plot for ~$250 more. vs Siglent SDS804X HD: the Siglent has 2 GSa/s and 100 Mpts but a fan; the Rigol is silent (USB-C powered) with the bigger hack ceiling.

Gotchas to know
- Stock memory is 25 Mpts and the usable depth has quirks at some settings — the 'memory depth is a deal breaker' EEVblog thread is worth reading before relying on long captures.
- Fan-less but the case runs warm; give it ventilation.
- Bundled probes are 100 MHz-class — fine stock, limiting if you unlock to 250 MHz.
- 1.25 GSa/s shared across channels: four channels active = 312 MSa/s each.
