Digital Phosphor Oscilloscope Performance Indicators
Digital phosphor oscilloscope is an oscilloscope platform that has various traditional advantages of digital storage oscilloscopes (DSO), from data storage to advanced triggering functions. At the same time, it also has the analog real-time oscilloscope ART (Analyzed The light and dark display and real-time characteristics of Real Time can produce chemical fluorescence effects in digital form that are better than the gradual change in brightness of the analog oscilloscope CRT (Cathode Ray Tube).
Features of digital phosphor oscilloscope
DPO has made a new breakthrough in oscilloscope technology. It can display, store and analyze complex signals in real time, and use three-dimensional information (amplitude, temporality and multi-level brightness to display the frequency of amplitude components with different brightness) to fully display the signal. Features, especially the use of digital fluorescence technology, can display the history of signal changes over a long period of time through multi-level brightness or color.
The automatic measurement and waveform storage functions of DSO once amazed many engineers, but people soon discovered that when DSO measured high-frequency signals with low-frequency modulation, its display results were inconsistent due to its insurmountable aliasing distortion problem. This reminds me of the benefits of ART oscilloscopes.
DpO not only has the real-time brightness and non-aliasing display capability of the ART oscilloscope, but also has the automatic measurement and waveform storage functions of the DSO. There are great improvements in avoiding the shortcomings of both. Mainly manifested in:
(1) Fast waveform capture rate and super display capability
The application of digital fluorescent display technology enables DpO to display multiple images of signals simultaneously in different grayscales or colors. DpO can record 200,000 waveforms per second. Its signal data is 1,000 times more than that of a general DSO. It can capture 500,000 waveforms each time. This fast waveform capture rate combined with superb display capabilities gives DpO the ability to analyze any detail of the signal. .
(2) Continuous high-speed sampling capability
Usually, DSO has an 8ms dead time between displaying two waveforms due to processing display data. Even a DSO that uses instavuTM sampling technology can only reduce this time to 1.7μs. ART oscilloscopes cannot capture waveform information during the retrace time. DpO can continuously sample hundreds of thousands of waveforms at the highest sampling rate, overcoming the stagnation problem of other oscilloscopes. The sampling rate of DPO is generally several 109 times per second. Such a high sampling rate allows the oscilloscope to have greater bandwidth.
