It has been around 70 years since Tektronix invented its first digital oscilloscope, and the performance and functionality of low-end digital oscilloscopes (500M) were getting better and better. With the Chinese oscilloscope into the market, oscilloscopes less than 500MHz have experienced different stages of development:
1. Larger and More Professional Display
Early digital oscilloscopes are generally equipped with a 4.5-inch or 5-inch LCD screen, display contents were limited. As early as 2009, OWON firstly launched 8-inch large screen oscilloscope (under 500MHz) SDS series products, the waveform display perfectly on larger and clearer screen, it hit the requirement of engineers at that time.
2. High Sample Rate under Deep Memory, High Waveform Capture Rate
In early age, less digital oscilloscope less than 500MHz has low storage depth, only a few K typically. As the sample rate and record memory are contradictory, when the sample rate is high, the storage capacity goes down. In 2010 OWON SDS series introduced in 10M memory which keeps 1GS/s sample rate. The reason is that SDS series used high-performance large-scale FPGA (Field Programmable Gate Array) ASIC (Application Specific Integrated Circuit) design technology with embedded high-performance microprocessor CPU and RAM (random access memory), and adopts fast segment storage Technology and hard disk storage, to solve this contradiction
3. Multi-function Oscilloscope for Different Test Environment.
The mixed-signal oscilloscope (MSO) was first introduced by Keysight for over a decade ago. It was later carried forward by more and more oscilloscope vendors. In this mode, oscilloscope is not only a time domain measurement instrument, but also extended its function to the multi-field measurement. The use of high-performance microprocessors and ASIC, can be measured on a number of nodes at the same time in the frequency domain, data domain and statistical domain for measurement and analysis. At present, the functional classification of the oscilloscope has been very vague, many manufacturers have integrated the signal generator and other basic measurement module into oscilloscope system. Take OWON’s XDS oscilloscope for example, its function covers oscilloscopes, arbitrary waveform signal generator, digital multimeter, data recorder and frequency meter. Module integration also improves the efficiency of data manipulation and analysis.
4. Higher ADC and Apply of Touchscreen
Since LeCroy introduced hardware 12-bit HBO series oscilloscopes in 2013, many engineers began to focus on vertical accuracy (ADC). 12-bit oscilloscope measurement accuracy is 16 times against the normal 8-bit oscilloscope, it can be a good tool for small voltage signals measurement and analysis of small signal components in large voltage signal.
And since the Apple mobile phone began to use the touch screen, more and more electronic products began to integrate it. With continuous function innovation of oscilloscope (such as complex waveform calculation and input settings) develop, more and more manufacturers began to use the touch screen to replace the complexkey operation.
From 2016, many well-known international oscilloscope manufacturers begin to promote high-precision and touch screen products, including Tektronix, RS, Keysight and etc. It is expected that high precision and touch screen will be one of the standard configurations for future oscilloscopes. And OWON began to trial apply on touch screen to the oscilloscope as early as 2014, and in 2015 officially released oscilloscope XDS series - the first integrated hardware 12-bit ADC and touch function oscilloscope. The XDS 200M oscilloscope launched in 2017 is equipped with a 14-bit ADC, lead the display resolution to a higher level..
Of course, in additional to the market welcomed features, XDS series oscilloscope still keep on OWON’s product characteristics. Battery module power assures field measurement and the implement of float measurement. What’s more, OWON also deeply focuses on education and set up a wireless educational management system based on XDS’s WiFi module. Through WiFi connection, this system can achieve one to all experimental project teaching, improving class efficiency. OWON keep on getting the needs of the market requirement, running in the front of the market, bring more and more innovation product to the vast number of consumers.
