High-frequency events that occur only once must be sampled when they occur. Real-time sampling challenges the scopeвЂ™s accuracy. The minimum sample rate suffices if you are observing slow-changing signals over a long period of time. According to this вЂњruleвЂќ the minimum sample rate must be twice the highest frequency, or 5-times as fast as what is minimally acceptable. The Nyquist вЂњfive times ruleвЂќ is used to ensure signals are accurately reconstructed. It shows how much waveform data the scope is able to capture. Sample rates define how many times per second (GS/s) a signal is read. Input signals are sampled at a high frequency (sample rate) and converted into a digital format. Regardless of what they are being used for or their cost, these scopes should be easy to use, accurate and deliver maximum performance. Oscilloscopes offer numerous features and functions. They are used in medical, telecommunications, scientific labs and automotive industries to analyze equipment, maintain electronics monitor medical, science, and engineering laboratory processes and procedures. Oscilloscopes measure electrical signals generated by pressure, stress, sound, light or heat. The Main Characteristics of Oscilloscopes Software programs control and produce signal sweep rate, deflections, analysis, storage and other features. TodayвЂ™s digital storage oscilloscopes (DSO) display graphic output of sound, voltage or vibration signals generated over time. Older cathode ray oscilloscopes (CRO) use electron beams to detect changes in an electrical signal and generate waveform images that are displayed on its screen. Recorded voltage patterns (over time) can tell you the status of power surges or why your ignition doesnвЂ™t seem to be working. It is вЂњas accurate as the data going into itвЂќ. An oscilloscope allows you to test circuitry for electrical current competence and safety.
