|GW Instek GDS-3254 8"" LCD Color Display Digital Storage Oscilloscope with USB Port, 250MHz Bandwidth, 4-Channel, 1.4ns Rise Time
GW Instek GDS-3000 Series Digital Storage Oscilloscopes, which creates a new benchmark of DSO value in the field. With 5GSa/s sampling and Visual Persistence Oscilloscope (VPO) technology, GDS-3000 displays waveforms truthfully and captures less-frequently-occurred signals, like glitches or runts, simultaneously without missing any spot of waveform information. A 100GSa/s ET sampling rate (10ps pt-pt resolution) is provided to accurately reconstruct repetitive waveforms avoiding software interpolation distortion. The 5GSa/s real-time sampling combined with a good variety of trigger selections enable the capture of fast and complex signals and display waveforms with Sinc interpolation. The 8” LCD with SVGA (800 x 600) resolution provides an ample display space to accommodate multiple waveform signals, on-screen menu, setting status and associated measurement information, giving all-at-a-glance convenience. A unique Split-screen feature allows each input channel to be operated independently with respective setting and waveform display. This gives users flexibility to use the GDS-3000 Series as a multi-scope-in-one DSO.
5GSa/s Sampling & VPO Technology
The GDS-3000 Series adopts VPO (Visual Persistence Oscilloscope) signal processing technology to enhance the performance of multi-gray-scale waveform display. The FPGA parallel processing, instead of conventional microprocessor architecture, is applied in GDS-3000 Series design to significantly increase the data processing speed and therefore increase the waveform update rate. This technology allows the GDS-3000 Series to display waveforms with various gray scales based on the occurrence frequencies, a fashion analogous to the analog oscilloscope display. As the visual persistence oscilloscope contains 3-dimension waveform data, including amplitude, time and intensity, for each waveform spot, it provides more useful signal information than a normal digital storage
oscilloscope can do. The high-speed data processing of VPO technology enables the signal analysis of rapid events such as video, jitter, glitch and runt.
The GDS-3000 Series features a maximum real-time sampling rate of 5GSa/s, which is superior to most of the equivalent oscilloscopes available in the market today. (2.5GSa/s maximum sampling rate for GDS-3152 & GDS-3252). The series is also equipped with an equivalent- time sampling rate of 100 GSa/s, providing an economic solution for the waveform acquisition and reconstruction of very high-speed repetitive signals. The fast-acquisition capability along with VPO signal processing technology, make GDS-3000 a very handy tool for observing occasionally-occurred signals such as transient and inrush events. With powerful technology, GDS-3000 Series gives you full confidence in every acquisition of complex waveform that adheres to high-speed circuit design of modern products.
Unique Split Screen Function
The unique split screen feature of GDS-3000 Series allows each input channel to be operated independently with respective setting and waveform display. The time base, the vertical sensitivity, and the trigger selections can be done by each channel separately, and the waveform of each input signal can be shown on the individual part of the screen. This nearly four-DSO-in-one feature is very useful for the applications that need to simultaneously see the details of multiple waveforms with very different characteristics. The 8-inch high resolution 800x600 LCD display makes the split screen a pleasant observation environment to view the details of complex signals.
Complete Set of Trigger Functions
Besides Edge trigger, the GDS-3000 Series also offers various trigger functions, including Video, Pulse Width, Runt, Rise Time & Fall Time(specific time length), Alternate, Delay by Time, Delay by Event, and Hold-Off. The high sampling rate, the VPO signal processing & display, and the flexible trigger function all together make the GDS-3000 Series a powerful tool for waveform capture and display of various types of signals.
Auto Range for Both Time Base and Vertical Scale
The Auto Range function automatically adjusts the time base and/or the vertical scale of displayed waveform when the frequency and/or the amplitude of input signal changed. This function gives user the convenience to have DSO always display waveform in a proper fashion on the screen tracking the frequency and amplitude changes of the input signal. It is especially useful when the user needs to alternately probe and test multiple circuit points containing signals with different frequencies and amplitudes.
Dual Display Window Zoom
The GDS-3000 Series Window Zoom function provides dual display mode to show the main waveform and the magnified section of zoomed-in waveform at the same time. Under “Zoom” mode, the width and the position of zoom-in window over the main waveform can be selected to get the magnified waveform as needed for detailed observation. To quickly and accurately move the zoom-in window to the expected position, the “Coarse” mode helps move the window to the needed position immediately and the “Fine” mode provides fine adjustment to precisely place the window in the exact position.
Serial Bus Triggering and Decoding (Optional)
With serial bus technology being widely used in embedded applications, the proper triggering and analysis of flowing data, control signal and associated pulse waveforms in serial bus communication has been a difficult job and challenge to design engineers. The Serial Bus Analysis software of GDS-3000 Series carries complete analysis tools for triggering and decoding of commonly used serial bus interfaces, including I2C, SPI and UART. Without spending time to study serial bus regulation details, the user only needs to set the trigger condition on GDS-3000 to get the data slots of interest.
Power Analysis Software for Power Supply Measurements (Optional)
The Power Analysis software contains four measurement functions, including Power Quality, Harmonics, Ripple and Inrush Current. The Power Quality analysis function allows the measurements of Voltage, Current, Frequency, Power and other quality related parameters for power source efficiency improvement. The Harmonics analysis function performs evaluation of power waveform distortion and gives harmonic test data for power source design and quality check. This function is complied with IEC 61000-3-2 standard. The Ripple measurement function, acquiring the ripple and noise overriding the DC waveform, is used to evaluate the DC power source quality. The Inrush Current measurement function is used to measure the power-on surge current, which may cause the damage of the device circuit.
Extendable Application Software
The GDS-3000 Series allows future installation of additional application software at the user site. This provides an open environment for optional software upgrade and additional feature built-in whenever the GDS-3000 user has the need. The flexibility of software installation platform keeps the DSO being in use always up-to-date.
Various Interfaces Support
Two high-speed USB 2.0 Host ports located in both front panel and rear panel are used for easy access of stored data. In the rear panel, a USB Device port is available for remote control and hardcopy print-out through a Pictbridge compatible printer. RS-232 and LAN interfaces are provided as standard for system communication & ATE applications. A SVGA video output port allows the transfer of DSO screen image to an external projector or monitor for remote monitoring or big screen observation. A GPIB to USB adaptor is available as an option for interface conversion though the USB Device port in the front panel.
A New Platform of High Technology.
The GDS-3000 Series is a new platform of 4-input channels, 350MHz bandwidth, 5GSa/s sampling rate, and VPO waveform display. The split screen feature has been designed to meet the requirements of multi-window & multi-signal tests in the research and the manufacturing fields.
