Network storage function
Oscilloscope chooses appropriate storage depth, also called record length
Storage depth is a measure of how many sampling points an oscilloscope can store. If you need to capture a pulse string continuously, you need the oscilloscope to have enough memory to capture the entire event. The required storage depth can be calculated by dividing the length of time to be captured by the sampling rate needed to accurately reproduce the signal.
Storage depth is closely related to sampling rate.The depth of storage you need depends on the total time span to be measured and the required time resolution.
Modern oscilloscopes allow users to select record lengths to optimize the details of some operations. Analysis of a very stable sinusoidal signal requires only 500 points of record length;But to parse a complex stream of digital data, you need a million points or more of record length.
Capturing the effective trigger of the signal in the right position can usually reduce the storage capacity of the oscilloscope.
DPO and development of oscilloscope technology
The application of digital fluorescence display technology enables DPO to simultaneously display multiple images of signals in different shades or colors. DPO clock can record 200,000 waveforms per second, and its signal data is 1000 times more than ordinary DSO, and each time can capture 500,000 waveforms. This fast waveform acquisition rate combined with excellent display ability enables DPO to analyze any detail of the signal.
Usually DSO for processing display data in the display between two waveforms have 8 ms dead time, even if the sampling technologies adopted instavuTM DSO this time also can reduce to 1.7 mu s, ART cannot capture the waveform oscilloscope in flyback time information and DPO can always at the highest sampling rate of continuous sampling of hundreds of thousands of waveforms, overcome the other between stagnation into the problems of the oscilloscope. The sampling rate of DPO generally has several 109 times per second, which allows oscilloscope to have larger bandwidth.
