The 5 Best Rigol Oscilloscopes

Rigol Oscilloscopes Reviews

Rigol oscilloscopes are well-known for producing quality, yet inexpensive, oscilloscopes for hobbyists and electrical engineers on a budget.

Rigol Technologies Inc. was founded in 1998 and they produce technology products primarily focusing on electronic measurement and chemical analysis.

They are headquartered in Beijing, China and their primary mission is to produce low-cost, quality research and technology products for engineers, educators and researchers to help them solve measurement challenges in an affordable way.

Indeed, oscilloscopes are essential devices for any professional engineer. They enable electrical engineers to detect electric signals that are varying over time. This is essential for troubleshooting circuits, detecting information related to amplitude, noise, frequency or any other type of characteristic that could be changing over time.

Our Top Rigol Oscilloscope Pick

Our top pick is the 5.29 lb., 11.9" x 5.2" x 6.1" benchtop, Rigol DS1102E Digital Oscilloscope- it is a 100MHz option that features: 

  • 12 analog channels,
  • automatic measurement of 20 types of wave parameters (10 voltage and 10 time parameters),
  • a million point deep memory,
  • a max sample rate of 1 GSa/second,
  • and a usb interface.

It is an AC powered option that also ships with the PC software UltraScope and 2 probes- 1x or 10x selectable, and includes 2 probe hook tips. Users provide highly favorable feedback- saying that it is a great value purchase, with a solid plastic build-quality, functional buttons, and a cost of about a 10th of what a professional-quality oscilloscope would.

Some say the software is junk, while others say that with some ingenuity, a fresh download of Windows drivers, and a read-through of the Rigol FAQ, that it became a useful if somewhat remedial software resource.

On the downside, the fan is a little bit noisy and some users say that if you are looking for highly subtle measurement capacities, that it would be better to purchase professional engineering equipment, but these Rigol oscilloscopes are great value for experimenting hobbyists or electrical engineering students.

Rigol oscilloscope buying guide

The essential duty of an oscilloscope is to plot on a graph electrical signals as they vary over time. In general, these o-scopes will generate this information on a 2-dimensional graph where time is plotted on the X axis and voltages plotted on the Y axis.

The oscilloscope will include controls around the screen that will enable you to adjust the adjust the graph scale horizontally and vertically, enabling you to focus in on the signal. Some users prioritize portability in their o-scopes and others prefer traditional o-scopes.

When engineers are looking for a quality oscilloscope, whether it be from Rigol, Siglent, Hantek, or Tektronix, they prioritize:

  • a high number of channels,
  • USB connectivity,
  • fast sampling rates,
  • functional computer interfacing software,
  • high bandwidth,
  • convenient carrying handle,
  • coherent instructions,
  • robust internal storage,
  • and a solid warranty.

Besides these essential functionalities, many of these oscilloscopes also have additional measurement tools that let you easily measure a variety of other waveform characteristics.

Oscilloscopes are able to assess time characteristics as well as voltage characteristics. Within timing characteristics, they can assess frequency and period, duty cycles, rise and fall times. Within voltage characteristics, they can assess amplitude, maximum and minimum voltages, as well as mean and average voltages.

Oscilloscope terminology

There are a variety of oscilloscope terms that you should become familiar with prior to using your Rigol scope. Make sure to investigate your oscilloscopes bandwidth, which describes how fast they're able to see signal changes.

The channel amount refers to how many signals it can lead to a single time. Vertical sensitivity refers to the minimum and maximum oscilloscope values on the vertical voltage scale.

Difference between analog and digital oscilloscopes

There's also a bit of a confusion sometimes regarding the differences between digital and analog also scopes- electronic scopes can either be digital or analog. Analog scopes will employ an electron beam to assess input voltage. Digital o-scopes, on the other hand, will use microcontrollers to assess the input signal employing an analog-to-digital converter to generate this display.

In essence, analog o-scopes are generally older, feature lower bandwidths, and include fewer features, but they typically have faster response times.

Final thoughts

The specifics of scoping signals can get pretty complex and is beyond the purview of this particular post, but there are a variety of useful resources on the Internet, including YouTube videos, to go into the nitty-gritty of oscilloscope functionality should you need a primer.

We've included some helpful links below, and sprinkled within this post, but suffice it to say that a Rigol oscilloscope is a quality device ideal for amateur and intermediate professionals on a budget.
