Description
Fast clock edges and high-speed serial lines punish a scope that runs short of bandwidth. The Rigol MHO984 oscilloscope reaches 800 MHz on its 50 ohm input path, while it keeps 12-bit vertical resolution. Lost in HCM lists it for rental and sale, so you can borrow or buy it, and service is available on request.
Two input paths, two limits
The 800 MHz figure applies at 50 ohm with one or two channels active. However, the 1 Mohm input stops at 500 MHz. With all channels active, bandwidth falls to 400 MHz. Therefore decide first whether your probes and signal sources can use the 50 ohm path.

| Waveform capture | 30,000 wfms/s vector; up to 1,000,000 wfms/s fast recording |
| Vertical resolution | 12 bit native |
| Display | 7-inch 1024 x 600 touchscreen |
Why sample rate and memory matter at 800 MHz
A fast edge needs enough samples to look clean, so sample rate matters. The scope samples at 4 GSa/s on one channel, then 2 GSa/s on half and 1 GSa/s on all. Standard memory steps down from 100 Mpts to 25 Mpts as channels increase, while optional memory reaches 500 Mpts. So a long capture can keep fine detail.
Fast recording for rare events
Vector mode captures 30,000 waveforms per second. Fast recording then climbs to as many as 1,000,000. That speed helps when a glitch appears once in a long run, because fewer events slip between captures.
Jobs for the Rigol MHO984 oscilloscope
High-speed digital debugging is the main use, such as clocks and memory buses. Engineers also check edge quality and ringing on fast signals. In addition, the scope can follow serial protocols next to analog rails, while R&D teams borrow the extra bandwidth during a peak.
Check the configuration
The 16 digital channels need the optional PLA2216 probe, and the waveform generator is optional too. So confirm what the delivered unit carries. Ask Lost in HCM about probes, firmware, licenses and calibration evidence. In addition, remember that Rigol lists the model, but availability needs a check.

MHO984 questions
What bandwidth do I get on the 1 Mohm input?
The 1 Mohm input stops at 500 MHz, while the 800 MHz figure applies at 50 ohm.
How deep can the memory go?
Standard memory is 100/50/25 Mpts for single, half and all-channel use. Optional memory then reaches 500/250/125 Mpts.
Does the scope include a waveform generator?
The generator is optional, so confirm the installed configuration with Lost in HCM.
