The GDS-3000 series employs VPO (Visual Persistence Oscilloscope) signal processing technology to improve the efficiency of waveform display capability with a high-speed waveform update rate and multi-level afterglow display.
The GDS-3000 series is designed with a high-speed FPGA parallel processing mode instead of the traditional microprocessor architecture, which greatly improves the data processing speed and waveform acquisition rate. The VPO technology enables the GDS-3000 series to display the frequency of the test signals in a multi-level afterglow similar to that of analog oscilloscopes. Because VPO technology oscilloscopes display signals that include amplitude, time, and signal strength in a three-dimensional waveform data to show each wave point, the GDS-3000 provides a lot of useful information on the screen compared to traditional digital storage oscilloscopes. High-speed waveform capture technology allows for more accurate analysis of fast events such as video, jitter, noise, and choppy signals.
The GDS-3000 series features a high-speed 5 GSa/s real-time sampling rate and a high-speed 100 GSa/s equivalent time sampling rate for more precise waveform reconstruction of repetitive signals, providing a cost-effective waveform testing solution for the market. The high speed signal acquisition capability along with the VPO signal capture technology makes the GDS-3000 series ideal for observing video, occasional signals and surge events...instantaneous events. Backed by the GDS-3000 series' powerful technology, you can have full confidence in every complex signal acquisition process.

High-speed waveform capture technology allows for more accurate analysis of fast events such as video, jitter, noise, and choppy signals.
In addition to passive probes, the GDS-3000 series can also be equipped with differential or current probes for additional test applications. Three 25MHz, 50MHz, and 100MHz differential probes, and two new 50MHz/30A and 100MHz/30A current probes are available with the GDS-3000 to provide a total solution for a wide range of power test applications.
