Top 4 Best Cheap Oscilloscopes

Rigol Digital Oscilloscope

No products found.

The Rigol Digital DS1054Z is our best overall pick. It is compact and lightweight, with a simple interface for measuring voltage waves that suits different skill levels.

The Rigol’s 7-inch display uses ultra vision tech to show all channels on one screen. This makes it a useful option for beginners.  

The built-in calibration function helps hobbyists get reliable control after switching on, without guesswork or manual adjustments.

Waveform capture runs at 30.0 wfms/sec, the highest in its class for speed and efficiency. A USB Port also accepts a flash drive.

The Rigol oscilloscope produces no distortion and resists scratching. Its durability is useful on the job.

This device is also known for its high MHz rating and it will help you get the most data from the signals you are verifying. 

We rate the Rigol Digital as the best overall oscilloscope for its performance and straightforward interface. It suits both professionals and beginners. 

Tektronix Digital Oscilloscope

No products found.

The Tektronix TBS1102B Digital Storage oscilloscope is our premium choice for its range of functions. 

As soon as the device captures a signal, its advanced math will accelerate analysis. You are able to determine rise-time or frequency through the 16 automated measurements available. Also, the device helps you isolate the signals you are interested in. 

Another useful feature is its Time Limit function that helps you to identify any odd issues within the signal. Due to this self-debugging process, the Tektronix oscilloscope is perfect for many electronic applications such as product design, debugging or repair and servicing. 

Its intuitive interface makes it an excellent choice for apprentice electricians willing to get more diagnostics. This interface also includes auto-ranging, auto-setup and dedicated per-channel controls. 

The USB port transfers waveform data and screen captures to your computer. You can also print directly from a PictBridge-compatible printer.

Lightweight and compact, the Tektronix TBS1102B oscilloscope comes with a 5-year warranty. Although the price is a little higher, its advanced features make it the best choice for an apprentice electrician. 

Hantek Digital Oscilloscope

No products found.

If you want a good and inexpensive oscilloscope, we recommend you the Hantek DSO4102C digital oscilloscope. This is the perfect device for hobbyists and electricians on a budget. If you want both a multimeter and an oscilloscope, this is your pick. 

Hantek oscilloscope is a lightweight and compact model with well-balanced parameters in the channel mode. When used in Dual Channel mode, this device reaches up to 35 MHz speed thus being one of the fastest tools in its range. 

Another awesome feature is its memory depth – the single band channel holds 32k memory while the dual-band channel detains 16k memory. You will be able to keep multiple data sources with no issue. 

The Hantek Digital Oscilloscope is a budget option with push-button controls in place of a rotating knob. The controls take little time to learn and keep the device comfortable to use while moving around.

With 6 hours of battery power autonomy, this oscilloscope is perfect for daily use. And it also comes with two channels with a 2GS sample rate through each of them. You will get accurate readings in no time. 

As a minor drawback, the Hantek device requires software if you want to use the DSO Analyzer through a computer. This way you will be able to save, analyze and share your accurate readings.  

The Hantek DSO4102C is worth considering for an apprentice’s equipment. The package includes all required accessories.

Siglent Digital Oscilloscope

No products found.

The last product we’ve reviewed for you is the Siglent SDS1104X-E, an oscilloscope that comes with 4 channels and 100 MHz bandwidth. 

If you are an advanced user and you need a device capable to perform different math operations, this is the best oscilloscope you can buy. It is capable to perform mathematical operations such as signal multiplication, division, subtraction and addition. 

Siglent device includes multiple trigger mode options for signals such as SPI, UART/RS232 or CAN. It uses Phosphor Technology which eases signal accuracy. Moreover, the signals are displayed on its 7″ LCD screen and there are also web browser and WiFi controls. 

This oscilloscope is also power-efficient as it uses 25W, lower than the average 50W. Its lower power use helps reduce energy bills. 

What we did not like is the fact that it tends to have issues capturing frequencies under 199 kHz. However, it still has a capture rate of 40,000 waveforms a second with its Zoom Measurement/Gate features. Plus, its interface is a little too complex for beginners although they learn how to use it very quickly. 

The Siglent digital oscilloscope has a broad set of functions for hobbyists and apprentice electricians, with a learning curve for beginners.
