Rigol DS1054Z 4-Channel Digital Oscilloscope Review
Reviewed by Kerem Başbuğ · Last updated September 28, 2026 · How we rank
9.1 / 10 · our score
A 50MHz, four-channel benchtop oscilloscope sampling at 1GSa/s, from one of the best-known test equipment brands. It has been a standard recommendation for hobby benches for years because four channels make digital debugging far easier.

Our verdict
The DS1054Z earned its reputation by putting four channels on a hobby budget, and that is still its strength: watching a clock, a chip select and two data lines at once turns guesswork into diagnosis. Its bandwidth is modest, but for Arduino-class projects it is plenty, and the enormous user community means every question has already been answered online.
Pros & cons
Pros
- Four channels for watching several signals at once
- 1GSa/s sampling rate
- Large benchtop display
- Long-standing reputation with a huge user community
Cons
- 50MHz bandwidth is modest for the price
- Bulky compared with handheld options

Getting started with the Rigol DS1054Z 4-Channel Digital Oscilloscope
Colour-code your probes to the channel colours on screen before you start, which saves confusion once four traces are running. Compensate every probe. When debugging a microcontroller bus, trigger on the chip-select or clock line and view data on the other channels — that single habit is why four channels are worth having.
Who it's for
Makers debugging digital and microcontroller circuits who want four channels.

Rigol DS1054Z 4-Channel Digital Oscilloscope: common questions
Is the Rigol DS1054Z still worth buying?
For four-channel hobby debugging it remains a sound choice, largely because of its channel count, sampling rate and the depth of community knowledge around it. Newer models offer higher resolution and bandwidth at higher prices.
Why would you need four channels?
Digital circuits involve several related signals — a clock, data lines and control lines. Seeing them together, aligned in time, is how you find timing problems that a single channel cannot reveal.
Is 50MHz bandwidth a limitation?
For typical microcontroller projects it is adequate. If you work with fast edges or high-speed interfaces, choose a higher-bandwidth model.
