Description
A bench full of microcontrollers, sensors and serial buses needs more than a basic scope. The Rigol MHO954 oscilloscope answers with 12-bit vertical resolution, four analog channels and a 7-inch touchscreen. It belongs to the MHO900 family. Lost in HCM lists it for rental and sale, so you can borrow it for a project or buy it, and service is available on request.

How channel use changes the numbers
The headline figures belong to the lightest channel load. With one or two channels active, for example, the scope offers 500 MHz. With all four on, however, bandwidth drops to 400 MHz. Sample rate follows the same pattern, from 4 GSa/s on a single channel to 1 GSa/s on all of them. So plan your channel count before you compare it with other scopes.
Memory and capture speed
Standard memory is 100, 50 or 25 Mpts, depending on single, half or all-channel use. Optional memory then raises those figures to 500, 250 and 125 Mpts. The scope captures 30,000 waveforms per second in vector mode, while fast recording reaches up to 1,000,000. As a result, a rare glitch has a better chance of landing on screen.
Mixed-signal work with 16 digital inputs
The digital channels need the optional PLA2216 probe, so order it with the scope. You can then line up a bus with an analog rail and use trigger and decode functions to follow a serial exchange. A 12-bit converter also helps when small ripple rides on a larger signal.
Where a Rigol MHO954 oscilloscope earns its place
Embedded boards and sensor interfaces are the obvious fit, because the scope can decode a bus while it shows analog behavior. Teams also check supply rails for noise and ripple. In addition, teaching and R&D labs use a scope like this for bring-up, while a short project can rent one for a few weeks.
Confirm these items before you order
Do not assume that probes, memory upgrades, licenses or the optional waveform generator come with the unit. Instead, ask Lost in HCM to confirm the firmware, the installed options and the calibration evidence. Rigol lists the family, but availability needs a check for each unit. Also ask about the MHO984 in the same family if you need more bandwidth.

MHO954 questions
Do I get 16 digital channels out of the box?
No, because the digital inputs need the optional PLA2216 probe.
Does it run at 500 MHz on all four channels?
No. The 500 MHz figure applies to single or half-channel use, so all-channel use gives 400 MHz.
Is the photo my exact model?
The photo shows the MHO900 family front panel, but its marking reads MHO984. However, the specifications on this page are for the MHO954.
