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
  • Lower triggering jitter
  • Narrower pulse test width
  • More precise channel delay calibration

GAOTek Digital Fluorescence Oscilloscope provides a complete set of analysis tools for users, including markers based on waveform and screen, 29 kinds of parameter automatic measurements, mathematical operation, FFT analysis, advanced mathematics, waveform histogram, statistics, limit template test, power measurement and analysis, serial bus decode and analysis, etc.

Based on FPGA whole hardware decoding technique, GAO-DSO-101 improves the acquisition probability of random serial communication error codes.

GAOTek Digital Fluorescence Oscilloscope has a brand-new capacitance touch screen with user-friendly design which gives you excellent experience. The 10.4 in capacitance touch screen supports single-point and multi-point touch, can perform waveform scaling and movement swift. One-key zeroing design enables zeroing at horizontal, vertical and triggering positions. Digit and bus keypad greatly facilitates input speed. GAO-DSO-101 supports touch operation and mouse, push-buttons operation at the same time.

Multi-point capacitance touch screen performs waveform scaling and movement fast.

GAOTek Digital Fluorescence Oscilloscope provides over 20 types of free built-in training signals for educators, including sine wave, square wave, triangle wave, saw-tooth wave, runt pulse, repeated pulse, RF, digital burst, RS232, CAN, LIN, FlexRay and so on, which can help educators equip and upgrade labs.
