Which Oscilloscope To Buy
In my opinion, the Hantek DSO5102P is one of the best entry-level oscilloscopes you can get for such a price. It has a 100MHz bandwidth, a sample rate of 1G samples per second, a record length up to 40K, and a dual channel. Additionally, the USB port allows you to connect a USB drive to save pictures of the signals. You can also connect it to your computer and use the software provided to analyze your measurements in more detail.

The scope is straightforward to set up, and the menus are intuitive to use, which is perfect for beginners. For a more in-depth look at this oscilloscope, you can watch the video review below or read here: Hantek DSO5102P Digital Storage Oscilloscope (DSO) review.
It comes with 4 channels and offers 50 MHz bandwidth. It also comes with a USB connector, LAN(LXI) (you can connect an Ethernet cable), and AUX Output. This is a great oscilloscope when you take a look at price/performance.
Portable oscilloscopes look like multimeters but come with all the controls needed to visualize, analyze and record signals. One great option is the Hantek 3 in 1: Oscilloscope, Multimeter, and Signal Generator (2D72). As the name suggests, it is a multimeter, signal generator, and oscilloscope in a single tool. The controls and menus are not as intuitive as a regular oscilloscope, but it does a great job and occupies much less space. You can watch the following video review about this tool.
Very nice review of Oscilloscopes. I wanted to offer up another tool which would fall into your Toy/DIY category. It is the Espotek Labrador. It sells for under $30 and is quite useful for the following reasons:1) It fits onto a breadboard and is powered by USB2) The display is your PC and it can run on Linux/Mac/Windows3) Its 2 channels and also provides some limited additional functionality such as a signal generator.It is not a replacement for a the Oscilloscopes above, however, it is far better than the DSO138/150 models.For $30 its a remarkably usable and capable product that you can put on your breadboard and take quick measurements.
Instead of the Hantek 6022BE, I would suggest the Owon VDS1022. The Owon has slightly better specs and is slightly more expensive, but the big difference is that the 6022BE does not support single sequence triggering at its maximum sample rate, which I consider a serious deficiency.
But when it comes to choosing the best oscilloscope, how do you know which oscilloscope is right for your application? There are 10 primary factors to consider when you buy an oscilloscope. For a quick overview of the top factors, watch the short video below. Otherwise, keep reading for the full details on how to choose an oscilloscope for your application.
For example, a 100 MHz oscilloscope is usually guaranteed to have less than 30% attenuation at 100 MHz. To ensure better than 2% amplitude accuracy, inputs should be lower than 20 MHz. For digital signals, measuring rise and fall time is key. Bandwidth, along with sample rate, determines the smallest rise-time that an oscilloscope can measure.
The probe and oscilloscope form a measurement system that has an overall bandwidth. Using a low-bandwidth probe will lower the overall bandwidth, so be sure to use probes that are matched to the scope.
Rise time describes the useful frequency range of an oscilloscope, and this is a critical measurement in the digital world. Rise time is often considered when measuring digital signals like pulses and steps.
In order to accurately capture the details of rapid transitions, an oscilloscope must have sufficient rise time. Fast rise time is also needed for accurate time measurements. To calculate the oscilloscope rise time required for your signal type, use this equation:
A Mixed Signal Oscilloscope adds digital timing channels, which indicate high or low states and can be displayed together as a bus waveform. Whatever you choose, all channels should have good range, linearity, gain accuracy, flatness, and resistance to static discharge.
High-voltage differential probes: Differential probes allow a ground-referenced oscilloscope to take safe, accurate floating and differential measurements. Every lab should have at least one.
A good basic scope for example will store over 2,000 points, which is more than enough for a stable sine-wave signal (needing perhaps 500 points), whilst more advanced high-end scopes would have up to 1Gpoints, which is essential for working with high-speed serial data type applications.
Oscilloscopes with high waveform capture rates provide significantly more visual insight into signal behavior, and dramatically increase the probability that the oscilloscope will quickly capture transient anomalies such as jitter, runt pulses, glitches and transition errors.
Digital storage oscilloscopes (DSO) employ a serial processing architecture to capture from 10 to 5,000 wfms/s. Some DSOs provide a special mode that bursts multiple captures into long memory, temporarily delivering higher waveform capture rates followed by long processing dead times that reduce the probability of capturing rare, intermittent events.
Most digital phosphor oscilloscopes (DPO) employ a parallel processing architecture to deliver vastly greater waveform capture rates. Some DPOs can acquire millions of waveforms in just seconds, significantly increasing the probability of capturing intermittent and elusive events and allowing you to see the problems in your signal more quickly.

An oscilloscope, formerly known as an oscillograph, graphically displays electrical signals and shows how they change over time. Learn more about how an oscilloscopeworks, what they're used for andthe types of oscilloscopes.
An oscilloscope measuresvoltage waves by capturing physical phenomena such as vibrations or temperature, orelectrical phenomena such as current or power with a sensor.The oscilloscope then converts that signal into a waveform and graphically displays it where thehorizontal axis represents time and the vertical axis represents voltage.
There are two main types ofoscilloscopes: analog and digital. Most engineers today use digital oscilloscopes, whichfall into five categories: digital storage oscilloscopes, digital phosphor oscilloscopes,mixed signal oscilloscopes, mixed domain oscilloscopes, and digital sampling oscilloscopes.
Like a mixed signal oscilloscope, a mixed domainoscilloscope measures analog and digital signals, but has built-in spectrum analyzer,allowing engineers to make radio frequency (RF) measurementsas well.
Scientists, engineers, physicists, medical researchers, automotive mechanics, repair technicians andeducators use oscilloscopes to see signals change over time. There is no shortage of applicationsfor this powerful instrument.
