The RIGOL Digital Oscilloscope DHO804 is a versatile and feature-packed device, perfect for professionals and enthusiasts in the electronics field. It offers a 70MHz bandwidth, which is sufficient for analyzing a wide range of signals. The sample rate of 1.25 GSa/s ensures high-resolution signal capture, and with 12-bit vertical resolution, it provides more detailed and accurate measurements compared to many 8-bit oscilloscopes on the market. The four analog channels allow for multi-signal analysis, making it a handy tool for complex troubleshooting and development tasks.

The memory depth of up to 25 Mpts means you can store extensive data for in-depth analysis. The oscilloscope's ultra-low background noise and high waveform capture rate (up to 1 million wfms/s) help to detect even the smallest signal anomalies, enhancing its reliability and precision. The 7-inch HD touch screen enhances the user experience with clear visuals and intuitive controls. Connectivity options including USB, LAN, and HDMI ports offer flexibility for data transfer and external display connections.

The compact form factor and lightweight design make it portable and easy to handle. However, the 70MHz bandwidth might be limiting for users who need to analyze higher frequency signals. Additionally, while the device supports a high-definition display and interactive controls, it might have a learning curve for beginners unfamiliar with advanced oscilloscopes. The 3-year warranty provides peace of mind, ensuring durability and long-term reliability. Accessories like probes, power cable, and USB cable are included, making it ready to use out of the box. This oscilloscope is a solid choice for those looking for a mid-range option with robust features and dependable performance.

The FNIRSI DPOS350P is a versatile handheld oscilloscope that combines four tools in one: a 350 MHz bandwidth oscilloscope, a spectrum analyzer, a frequency response analyzer, and a DDS signal generator. With its 1 GSa/s sample rate and 2 channels, it covers many basic and intermediate testing needs, making it a good fit for electronics hobbyists, students, and field technicians who require portability and multifunctionality. The 7-inch touchscreen with digital phosphor display offers clear visuals and easy interaction, which is helpful if you prefer a tablet-like experience.

It also includes smart features like the ability to store 500 waveforms and 90 screenshots, as well as USB-C charging with an 8000 mAh battery, making it suitable for extended use away from a lab. On the downside, the memory depth of 60 Kpts is moderate, meaning very long signal captures might be limited compared to larger benchtop scopes. While the handheld form factor is great for mobility, it may not replace full-sized oscilloscopes for very detailed or specialized lab work.

The spectrum analyzer and frequency response analyzer functions add extra value, especially for users needing signal integrity and filter analysis. This device provides a solid balance of features and portability for those who want more than just a basic oscilloscope, but don’t require high-end lab equipment.
