It is no secret that digital oscilloscopes are sampled data instruments and do not acquire a continuous record of the input signal. We know from sampling theory that the input signal, properly sampled ...

Oscilloscope waveforms show real world electronic signals. How well the scope displays those waveforms determines its performance. Assuming two scopes have adequate base specifications – like ...

Pico Technology has introduced the DeepMeasure analysis tool. Included as standard with PicoScope 3000, 4000, 5000, and 6000 Series oscilloscopes, DeepMeasure delivers automatic measurement of ...

All of today's high-speed real-time sampling oscilloscopes use various forms of digital signal processing (DSP) on digitized oscilloscope waveforms. Some engineers are concerned that filtering ...

Today’s oscilloscopes have far more functionality than their old cathode-ray tube (CRT) analog counterparts. At first glance, the proliferation of all of those knobs and buttons may seem overwhelming, ...

USB-based oscilloscopes are becoming increasingly popular. Performance enhancements and new levels of functionality mean these instruments are becoming more attractive to test engineers. They can be ...

Download this article in PDF format. An oscilloscope is used to measure the voltage change of a signal over time. After a digital multimeter, an oscilloscope is typically the second most common piece ...

The other day, I received a request for information on digital oscilloscope fundamentals. A very nice gentleman, Ed, had just purchased his first digital scope and was looking for help in learning its ...

Most of us remember the first time we used an oscilloscope. With one look at the large display, we could tell what was happening to our waveforms. From the earliest days, oscilloscopes have been a ...
