The GDS-2000A series provides the flexibility of easy conversion from a DSO into a MSO (Mixed Signal Oscilloscope) under a plug-and-play concept. As two plug-in compartments are available at the rear panel to accommodate various plug-in modules, the GDS-2000A series DSO with an 8 or 16 digital channels module performs MSO functions perfectly at the user’s installation of the module. The analysis and decoding functions of parallel bus and serial bus such as I2C, SPI, and UART are supported after the module is installed. GDS-2000A is regarded as an effective tool in signal analysis, trouble diagnosis and debug.

The plug-in module of DDS (Direct Digital Synthesis) based function generator is provided as an option of the GDS-2000A series. The function generator is able to generate Sine, Triangle and Square waveforms, with variable duty cycle of the square waveform. Two function generators can be used at the same time to provide dual output signals. With the stimulus source, the verification of electrical characteristics and functionality of the DUT (Device Under Test) can be done in one DSO.

Besides Logic Analyzer and Function Generator modules, the GDS-2000A series also provides optional LAN/SVGA Interfaces module and GPIB interface module for user’s selection. The Modularized Structure offers a dramatic elasticity allowing user to upgrade the DSO with field-installable options after the purchase of the main body. Two modules can be used simultaneously as the maximum capacity of the GDS-2000A options, which include (1) 8-Channel Logic Analyzer (2) 16-Channel Logic Analyzer, (3) DDS Function Generator (4) LAN/SVGA Interfaces Module, (5) GPIB Interface Module.

GDS-2000A Series is equipped with Zoom Window feature which enables users to display the detailed zoomed waveform located by the Zoom Window. Under Zoom mode, the entire inbound waveforms and zoom range cursors are displayed in the upper window, and the waveform details in the Zoom window are displayed in the bottom window. Users can tune the zoomed range by adjusting Time/Div selection, and pan the window by rotating the scrolling knob POSITION.

With a plug-in 8 or 16 digital channels module, a 12 or 20-channel MSO can be upgraded from DSO by on-site installation. The analysis and decoding functions of parallel bus and serial bus such as I2C, SPI, and UART will be processed after the module installation.

Besides, it can measure digital and analog signal of embedded circuit design by appropriate triggering function. Then further analyze whether the timing sequence is correct or not.

The GDS-2000A offers up to 36 waveform measurements including voltage/current, time/frequency, and delay measurements. 8 out of 36 measurements can be selected to simultaneously display on one single screen. With statistics mode, users can analyze mean, maximum, minimum, and standard deviation of the captured waveform. With the great amount of the analyzing statistics, users may ensure the integrity of the signal and the abnormal waveforms.

After installing the DataLog software, users can observe waveform variation for a long period of time to ensure products’ reliability. DataLog function allows users to set data storage timeframe and interval based upon their test requirements. Data storage can be waveforms or the CSV file for each channel. Data can be stored in USB, GDS-2000A or the remote site computer via LAN.

In the logic circuit analysis, “OR”, “AND”, “NOR”, and “NAND” four logic analyses are required and the most fundamental. Users can download and install, free-of-charge, the Advanced Logic software to their GDS-2000A equipped with logic analyzer to enhance the logic trigger and analysis function of digital circuits.

Integrated digital voltage meter, efficiently and simultaneously monitoring voltage, frequency and triggering and measuring intricate digital signals under limited resources, makes this DVM function a huge efficiency multiplier to easily tackle problems and changes users may encounter.

The advantage of H-Expansion is that engineers can move trigger point to any position on the screen and expand the fixed point. Engineers can observe expanded waveforms in great detail without missing the observation of the trigger point.

The GDS-2000A provides the options of two sets of  function generators. The function generators can produce diverse waveforms such as sine, square, triangle, and pulse waveforms. With this stimulus source, the electrical characteristics and functionality of DUT can be tested in one GDS-2000A, which fulfills measurement requirements from omni-dimensions.

Two standard USB interfaces located at both front panel and rear panel are used for easy access of stored data. USB device port at the rear panel is available for remote control or a hardcopy print-out through a PictBridge compatible printer. SVGA/LAN interfaces module (option), and GPIB interface module (option) are provided for ATE applications. SVGA video output (option with LAN) allows the results being transferred to external projector or large display screens.
