10 Best Digital Oscilloscopes 2025 in the United States

The Tektronix TBS2204B is a digital storage oscilloscope designed for users who require precision and versatility in their measurements. With a bandwidth of 200 MHz and a sampling rate of 2 GS/s, it offers a solid performance for a variety of electronic applications, making it suitable for both professionals and advanced hobbyists. The four analog channels allow users to observe multiple signals simultaneously, which is particularly beneficial when troubleshooting complex circuits.

One of the standout features is the 5 M record length on all channels, providing ample memory for capturing longer signal events. This is great for detailed analysis without missing crucial data. The 9-inch WVGA color display is another strong point, offering 50% more horizontal grids compared to many competitors, which enhances visibility and makes it easier to analyze waveforms clearly.

There are some drawbacks to consider. At 39.68 pounds, the oscilloscope is relatively heavy and might not be ideal for portable use or for those needing a device that can be easily transported. Additionally, while the specifications are impressive, beginners might find the professional-grade features overwhelming, as they require a certain level of expertise to fully utilize.

The SIGLENT SDS2204X Plus is a solid choice if you need a versatile digital oscilloscope with good performance. It offers a 200 MHz bandwidth, which is suitable for many general electronics and industrial troubleshooting tasks. Having 4 channels means you can observe multiple signals at once, which is helpful if you work with complex circuits. The sample rate of up to 2 GSa/s (gigasamples per second) ensures detailed signal capture, and the memory depth of 200 million points lets you record long waveforms without losing detail.

The 10.1-inch display is large and clear, making it easier to view waveforms and menus comfortably. Its triggering system is advanced, supporting serial bus protocols like I2C, SPI, UART, and CAN, which is great if you work with embedded systems; additional options can be added for more specialized protocols. The oscilloscope also captures waveforms very quickly, which helps when trying to catch rare or fast events. One thing to consider is its size and weight (over 10 pounds), so it’s more suited to a bench setup than portable use.

Connectivity details like USB or LAN are typically included in this model, allowing easy data transfer and remote control. This oscilloscope balances powerful features with user-friendly operation, making it a strong candidate for engineers, hobbyists, or technicians who need a reliable instrument for a variety of electronic measurements.

The GW Instek MDO-2204EX is a versatile digital oscilloscope with a bandwidth of 200 MHz, which is suitable for a range of applications including both basic and more demanding signal analysis tasks. It features four channels, allowing for simultaneous measurement of multiple signals, which can be particularly useful in complex diagnostic scenarios.

The oscilloscope also includes a spectrum analyzer, a dual-channel 25 MHz arbitrary waveform generator (AWG), a 5,000 counts digital multimeter (DMM), and a power supply, making it a comprehensive tool for electronics workstations. The integration of these additional tools eliminates the need for separate devices, saving both space and cost.

With dimensions of 5.01 x 15.12 x 8.19 inches and weighing 10.14 pounds, it is relatively portable but might be on the heavier side for some users. This oscilloscope should appeal to both professionals and hobbyists looking for a multifunctional instrument.
