Instek GDS-220


200 MHz, 2-Channel, 1 GSa/s Max, 1 M Memory Depth, Handheld Digital Storage Oscilloscope



The Instek GDS220 is a 200MHz 2 channel handheld digital storage oscilloscope. The GDS-220 introduces a 7" capacitive full touch panel LCD which can be positioned in portrait and landscape display. The recharging-battery design makes the series easy to operate for field operations. The GDS-220 is suited for applications in laboratories, R&D, large electric system tests, power product tests, motor tests, solar power battery inspection and repair, and maintenance personnel who are always on field assignments.

Full Touch Panel Capacitive LCD

GDS-220 adopts full touch panel capacitive LCD. In the era of smart phone explosion, GW Instek can also usher users into the full touch panel measurement era. With only one finger, users not only can move waveform up and down but also the trigger line position. Two-point touch panel is also applied. Engineers can use two fingers to adjust vertical voltage level and to enlarge or narrow time division scale. Additionally, one finger drag menu selection allows users to follow their intuition to locate required measurement functions, and to save and retrieve diagrams and data anytime anywhere.

Simultaneous utilization of Oscilloscope and DMM

The GDS-220, with two analog signal input channels, has a bandwidth of 2000 MHz and the maximum sample rate per channel is 1 GSa/s with a memory depth of 1 Mpts. The GDS220 has a 5,000 count DMM which can simultaneously measure and monitor AC and DC voltage, and current. Trend plots over long periods of time can also be drawn which allows engineers to effectively monitor standard electric parameters while measuring basic circuit signals.

Traditional oscilloscopes can not meet users' requirements of conducting integrated system circuit measurement. One extra DMM is often required to work with traditional oscilloscopes to handle enormous test requirements. The GDS-220 oscilloscope integrates the functions of oscilloscope and DMM to conduct simultaneous measurements. In the analysis of system circuit waveforms, GDS-220 can also use DMM to measure basic voltage and current of the peripheral components that provides users with very powerful test integration.

Optional Differential Probe

In many strict test and measurement environments, system power isolation and grounding problems have become one of the key issues. Bad isolation and grounding will have serious impact on circuit system safety. The Optional differential probe can achieve equivalent isolation results for measurement system and there is no grounding problem. Under today's economic constraints, using a differential probe to achieve isolation result is one of the best choices.

Briefing Material Compilation

Engineers or students often compile briefing material for work or class requirements. The completeness and convenience of briefing often determine users' performance. The GDS-220 provides a very strong briefing material compilation function. Before compiling briefing material, users can select different test and background conditions such as date, time and cursor. In addition, measurement parameters can also be determined based upon different requirements. This customer-made function not only shows the complete waveforms but also provides peripheral parameters to become the key communication bridge for work and class requirements.

GO/NOGO Template Editing

Go/NoGo testing function allows the user to check whether the incoming signal violates the user-defined template for examining waveforms. Users can easily define this template by setting the tolerance ratio to determine violation conditions. The function can freely adjust the size of template. A defect message will be shown if the DUT’s waveform is abnormal and touches the template. The function is not only a very useful measurement tool for production lines but also a very convenient tool for engineers to observe waveforms in a long period of time.

Tools Electrical Engineers Often Applied

The GDS-220 has built-in diversified application software to provide users with very thoughtful auxiliary tools. In the tedious circuit design process, engineering calculator software provides mathematical calculation functions from basic to advanced allowing engineers to thoroughly understand circuit response and parameter value. Resistance calculation software not only provides accurate resistance value for different surface embedded resistance codes but also color coding resistance value enquiry function. It is a very powerful auxiliary tool for users from students to senior electrical engineers.

Image Storage and Preview Function

The GDS220 can record screen images and preview images. In many complex test and measurement environments, engineers can not observe images from his or her computer immediately after images are stored. The image preview function allows users to make sure the file is correct right away. Pre-observation operation is also very convenient to users.

Used as an USB Storage Device

Once engineers finished waveform measurement and report compilation, the GDS-220 can be used as USB storage component to retrieve and store files. The USB connecting cable can be used to connect the GDS-220 with the PC or handheld device to retrieve any required files for follow-up actions. Today, smart phones are ubiquitous, the screenshots and measurement results of GDS-220 can also be transmitted via smart phone.
