1. Introduction
With the rapid iteration of the electronic information industry, the complexity and integration of electronic products continue to improve, placing more stringent requirements on core indicators such as accuracy, bandwidth, and sampling rate of electrical signal measurement instruments. As a key device that converts analog electrical signals into digital signals for processing and display, digital oscilloscopes directly determine the accuracy and reliability of electrical signal analysis. They are indispensable testing tools throughout the entire process of electronic products from R&D to mass production. By virtue of the strict selection of high-precision electronic components and precision circuit design, the LISUN OSP series(https://www.lisungroup.com/products/cfl-testing-instruments/multiplex-temperature-tester.html) digital oscilloscopes have broken through the limitations of traditional oscilloscopes in measurement accuracy, achieving world-class testing levels and providing strong technical support for high-quality testing of various electronic products. This paper will deeply analyze the core value of this series of oscilloscopes from three dimensions: technical advantages, performance parameters, and application scenarios, combined with specific data.

2. Core Technical Advantages of LISUN OSP Series Digital Oscilloscopes
2.1 Integrated Application of High-Precision Electronic Components
The core competitiveness of the LISUN OSP series digital oscilloscopes stems from the in-depth integration and optimized design of high-precision electronic components. This series of products adopts high-stability analog front-end chips, which can effectively suppress noise interference during signal transmission, significantly improve the ability to capture weak electrical signals, and ensure accurate measurement of small-amplitude signals. It is equipped with high-performance Analog-to-Digital Converters (ADCs), among which some models adopt 14-bit high-precision ADCs. Compared with traditional 8-bit ADCs, the precision loss during signal quantization is reduced by more than 90%, which can more truly restore the original electrical signal waveform. At the same time, key components such as the signal amplification module, trigger circuit, and clock circuit inside the instrument all select top-tier industry components. Through precise circuit layout and anti-interference design, high-precision measurement of parameters such as amplitude, frequency, and phase of electrical signals is achieved, and the overall testing accuracy reaches a world-class level.
2.2 Humanized Design and Multifunctional Integration
In addition to core measurement accuracy, the LISUN OSP series digital oscilloscopes have been fully optimized in practicality and operability. This series of products is equipped with a 7-inch or 8-inch large screen display, with a clear and intuitive interface, facilitating engineers to quickly read waveform data and measurement results. It supports multifunctional modes such as Print Snap, DAQ (Data Acquisition), and Math (Mathematical Operation), which can realize real-time storage, analysis, and export of measurement data, greatly improving testing efficiency. It has multi-channel synchronous measurement functionality; dual-channel and four-channel models can meet the signal testing needs of electronic products with different complexities, supporting synchronous capture and comparative analysis of multiple electrical signals, and providing convenience for fault diagnosis of complex circuits. In addition, some models such as the OSP3104ET also have an I²t measurement function, which can be directly used to calibrate the LISUN SBLL-3P20A self-ballasted lamp load cabinet, expanding the application scenarios of the instrument.

3. Analysis of Core Performance Parameters of LISUN OSP Series Digital Oscilloscopes
The LISUN OSP series digital oscilloscopes cover 8 core models. Each model forms a differentiated configuration in key parameters such as the number of channels, bandwidth, sampling rate, and vertical resolution, which can adapt to the testing needs of electronic products in different scenarios. The specific performance parameters are shown in the following table:

It can be seen from the parameter table that the series of oscilloscopes are divided into dual-channel and four-channel categories in terms of channel configuration: dual-channel models such as OSP1102 and OSP3202E are suitable for simple detection scenarios of single or two signals, such as power signal testing of ordinary consumer electronic products; four-channel models such as OSP3104E and OSP3204AE can meet the synchronous detection of multiple signals in complex circuits, such as multi-module signal analysis of industrial control equipment.
In terms of bandwidth and sampling rate, the bandwidth ranges from 100M to 300M, and the maximum sampling rate reaches 2.5G. Among them, the OSP3302 model, with a combination of 300M bandwidth and 2.5G sampling rate, can accurately capture high-frequency electrical signals, and is suitable for the detection of electronic products such as communication equipment and high-frequency oscillators; while 100M bandwidth models such as OSP1102 can meet the low-frequency signal detection needs of ordinary consumer electronics, low-voltage electrical appliances, etc.
The vertical resolution is divided into two levels: 8bits and 14bits. 14-bit models such as OSP3202A and OSP3104AE have obvious advantages in weak signal measurement, which can accurately distinguish small amplitude differences, and are suitable for fields with high requirements for signal accuracy such as high-precision sensors and medical electronics; 8-bit models can meet the testing needs of conventional electronic products and have a cost-effective advantage.
