Next-generation virtual persistence oscilloscopes, such as the GDS-3000 series, display waveforms with various grey scales based on the occurrence frequencies, comparable to the traditional analog oscilloscope display.

The VPO contains three-dimension waveform data, including amplitude, time and intensity, for each waveform spot, providing more useful signal information than a normal DSO digital storage oscilloscope.

The VPO high-speed FPGA parallel data processing, compared with conventional microprocessor architecture, enables the signal analysis of rapid events such as video, jitter, glitch and runt, as well as significantly increased data processing speed and therefore increased waveform update rate.

Apart from the VPO technology, the series includes other features that will redefine user expectations. An 8 screen dwarfs 5.7 screens found on traditional DSOs, the high SVGA 800 x 600 resolution exceeds traditional VGA 340 x 240 DSO resolution by several orders of magnitude and the practical SVGA video output port allows the transfer of DSO screen image to an external projector or monitor for remote monitoring or big screen observation.

Other features include the four windows split screen, window-navi tool, switching power measurement and serial data bus measurement such as I2C/SPI/UART. It also provides two or four analog channels, up to 350 MHz bandwidth, independent 25 k points record length for each channel, up to 5 GSa/s sampling rate and 3000/s frame waveform update rate.

The split screen 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 carried out by each channel separately, and the waveform of each input signal can be shown on the individual part of the screen.

Besides Edge trigger, the series also offers various trigger functions, including video, pulse width, runt, rise time and fall time (specific time length), alternate, delay by time, delay by event, and hold off.

The serial bus analysis software 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.

The optional power analysis software contains four measurement functions, including power quality, harmonics, ripple and inrush current.
