The features of DHO800 and DHO900




Excellent performance

First, let's look at the performance of the oscilloscope. The DH800 and DHO900 series boast high sampling rates of up to 1.25GSa/s, enabling accurate capture of high-frequency signals and detailed waveform analysis. Additionally, 12-bit vertical resolution means detailed signal characteristics can be precisely analyzed.


Multi-channel options

Whether you need two or four analog channels, these oscilloscopes have it covered. Additionally, the DHO900 series has up to 16 digital channels and is great at capturing digital signals. Multi-channel options are suitable for a variety of applications.


Long memory length

Another notable feature of the oscilloscope is its long memory depth. The DHO800 series supports up to 25M points, and the DHO900 series has up to 50M points memory depth available. This allows you to capture a lot of waveform data and perform detailed analysis. Long memory in an oscilloscope is crucial for applications requiring comprehensive data acquisition and detailed waveform analysis. It allows the oscilloscope to capture rare events, acquire high-resolution data, support protocol analysis, enable wide-timebase measurements, facilitate history and sequence modes for tracking signal changes, offer zoom and magnification for fine detail examination, store pre-trigger and post-trigger data for event context, and assist in statistical analysis. Long memory is valuable for engineers and researchers in electronics, telecommunications, and research, providing the capability to gain deeper insights into signal behavior and system performance over extended time intervals.


High waveform capture rate

DHO800 and DHO900 offer a maximum functional capture rate of 1,000,000 wfms/s. A high waveform capture rate is vital for oscilloscopes as it enables efficient and real-time signal analysis, ensuring the rapid acquisition of multiple waveforms, improved chances of capturing rare or intermittent events, advanced triggering and event isolation, signal integrity validation, interleaved acquisition, mixed-signal analysis, seamless debugging, accurate waveform averaging and statistical analysis, monitoring multiple signals simultaneously, and precise time-domain analysis. This feature is instrumental in a wide range of applications, from electronics development to troubleshooting complex systems, enhancing the instrument's ability to capture, display, and analyze signals with speed and accuracy.


Versatile interface and portability

The oscilloscope is equipped with various interfaces such as USB, LAN, and HDMI, making it easy to connect with other devices and external systems.



Furthermore, it uses a USB Type-C interface and can be powered using a mobile battery, eliminating the need for a power outlet. Additionally, the lightweight and compact design (1.78kg) makes it easy to transport to various measurement sites.



Comparison with competitive products

In the market, the DH800 and DHO900 series are clearly superior in their performance. Compared to competitive products, higher sampling rates and vertical resolution provide more accurate measurement results. It also offers excellent value for money, as comparable products from competitors often come at a higher price point despite offering similar performance.

 

Advantages of 12-Bit Oscilloscope

12-bit oscilloscopes are a type of digital oscilloscope that offers higher resolution than their 8-bit counterparts. In a 12-bit oscilloscope, each sample is represented using 12 bits of data, which allows for finer voltage resolution and more accurate measurement of signals. This can be especially useful when working with low-level or small amplitude signals, as the increased bit depth provides better measurement precision.


Higher-resolution oscilloscopes, such as 12-bit models, can be valuable for applications that require detailed signal analysis, including audio, RF, and power electronics testing. They can capture and display signals with greater clarity and accuracy, making them a preferred choice for certain tasks.

Keep in mind that as technology evolves, oscilloscope specifications and features may change, so it's a good idea to check with specific manufacturers and their product lines to find the latest 12-bit oscilloscope models available on the market.


Choosing a 12-bit oscilloscope over an 8-bit oscilloscope can offer several advantages in specific situations where high precision and greater signal detail are necessary. Here are some of the key advantages of a 12-bit oscilloscope compared to an 8-bit oscilloscope:

 

  1. Higher Resolution: The primary advantage of a 12-bit oscilloscope is its higher vertical resolution. It can represent voltage levels with 4,096 discrete values (2^12), compared to 256 values (2^8) in an 8-bit oscilloscope. This finer resolution allows you to measure and display voltage levels with greater precision.

  2. Better Measurement Accuracy: With its higher resolution, a 12-bit oscilloscope provides better measurement accuracy, especially when dealing with low-level signals. This is crucial in applications where precise voltage measurements are essential.

  3. Improved Dynamic Range: A 12-bit oscilloscope typically offers a wider dynamic range compared to an 8-bit oscilloscope. It can accurately measure both high-amplitude and low-amplitude signals within the same measurement. This is important when working with a broad range of signal amplitudes.

  4. Enhanced Signal-to-Noise Ratio (SNR): The higher bit depth of a 12-bit oscilloscope results in a better signal-to-noise ratio (SNR). This means it can capture and display weak signals with less noise interference, making it ideal for applications that involve detecting low-level signals or analyzing signals in noisy environments.

  5. Greater Precision in Waveform Analysis: A 12-bit oscilloscope is well-suited for detailed waveform analysis, such as accurate voltage measurements, signal shape analysis, and signal integrity testing. This precision is valuable in various fields, including electronics, telecommunications, and research.

  6. Reduced Quantization Error: With more bits of resolution, a 12-bit oscilloscope minimizes quantization error, which can be significant in 8-bit oscilloscopes. Quantization error is the discrepancy between the actual analog signal and its digitized representation, and lower error levels lead to more accurate measurements.

  7. Increased Flexibility for Advanced Applications: In applications where precise measurements are crucial, such as power electronics, RF engineering, audio analysis, and research, a 12-bit oscilloscope provides the flexibility and accuracy required for complex and demanding tasks.
