Working principle of digital phosphor oscilloscope
The powerful functions can complete the capture, display and analysis of complex signals, and the flexible angle generation method and automatic digital measurement function make it a leader in the field of measurement. The commonly used TDS3000 series has a sampling rate of 1.25-5GS/s and a bandwidth of 100-500MHz. The TDS500/700 series has a sampling rate of 2-4GS/s and a bandwidth of 0.5-2GHz. Of course, DpO will not have such superior performance. Low prices. In order to give full play to the performance of DpO, it is mainly used for the detection of complex flares.
(1) Signal detection in video application environment
This type of measurement field faces long "frame signals" composed of fast pulses. In order to capture the envelope of the entire signal, DSO can only use a slower sampling rate. The slower sampling rate will be caused by the lack of waveform data. Aliasing distortion: ART oscilloscopes can display wave profiles, but do not have measurement and analysis functions. DpO is particularly suitable for the detection of such signals. Similar signals such as read signals from magnetic disks, optical disks, etc.
(2) Detection of complex digital modulated signals in wireless communication equipment
The complexity of this type of signal is manifested as aperiodic signals. On the ART oscilloscope, only a blurry band of light can be obtained that cannot be identified. DSO is difficult to provide valuable information due to its limited storage depth. At this time, the DPO can be used to its full potential. Amplitude waveform capture capability.
(3) Detection of repetition frequency of rare events
This is an outstanding performance brought by DpO's digital fluorescence technology. By observing the display brightness of rare events in multiple waveforms, you can know the frequency of occurrence within a certain period of time. If necessary, you can even directly call up the waveform data in the three-dimensional database for analysis. Detailed statistics.
