Main Characteristics

GAOTek Digital Fluorescence Oscilloscope has a capture rate of 70 million frames /sec waveform, fast identification and capture of accidental events. 5 GSa/s sampling rate and 200 Mpts/Channel deep storage, burr and contingency capture rate can be greatly improved. Users can review more waveform details in a longer collection period.

GAOTek Digital Fluorescence Oscilloscope has a 256-grade gray scale and four types of waveform palettes for display which give you an extraordinary visual experience. GAO-DSO-101 oscilloscope implements digital phosphor three-dimensional display technique, to give the probability of event occurrence through lightness of color (256-grade gray scale) or temperature change (color grade), and to provide 4 types of waveform palettes including normal, reverse, color temperature and spectrum, which enhances the capability of contingency view for superior visual experience.

GAOTek Digital Fluorescence Oscilloscope supplies users with rich triggering functions, including edge, pulse width, video, runt pulse, logic, sequence, establishment of maintenance time, rise and fall time, HD digital video, serial bus triggering, which help users locate events in which they have interest out of complicated sampling information.

GAOTek Digital Fluorescence Oscilloscope uses the technique of precise digital triggering to perform triggering point determination against ADC samples collected, to restrain impact of interference signals, and to locate triggering events fast, to lay the foundation for accurate display and signal analysis of oscilloscope. Triggering jitter of the digital triggering is as low as ±1 ps, highest triggering sensitivity reaches 0.1 measure, narrowest pulse test width is 200 ps, and channel delay calibration step is 400 ps.

Advantages of digital triggering:

  • More precise triggering
  • More flexible triggering
  • Higher triggering sensitivity
