How to read a waveform on an oscilloscope

Oscilloscopes sample signals as they change over time and then plot those signals on a display. The amplitude of the signal is plotted on the vertical axis and time is displayed on the horizontal.

문서

What is the relationship between oscilloscope bandwidth and waveform rise time?

The formula can be stated in two ways, depending on what you're looking for. It is usually applied to the leading edge of a pulse in a dynamic system and is related to resistor-capacitor filter time constants and settling times.

Tech Tips - Multimeter or Oscilloscope?

MMs come in several flavors, including high accuracy (5 to 8 digits resolution), bench type, line-powered models that are not intended for field use. These DMMs are used in the lab, mostly for research and development or for production systems. An advanced model DMM can cost as much as a portable oscilloscope.

Foundation™ Fieldbus: System and diagnostic basics

The current trend in factory automation is to replace traditional control schemes in which each device has its own control wiring with bus systems that link a number of devices via the same cable. One benefit of bus networks is that they require far fewer cables and wires to connect devices to controllers. One of the most popular and widely used of these bus systems is Foundation Fieldbus.

Troubleshooting Programmable Automation Controller (PAC) I/O at the physical level

The heat, dust, corrosive chemicals, moisture, and vibration common to many work environments can degrade wiring and connections, however, and a harsh electrical environment can degrade signal quality. As a result, effective troubleshooting may require an examination of wiring, connections, and the electrical characteristics of the signals as they traverse the system

Why 500 MHz bandwidth matters

It's just common sense that the higher the oscilloscope bandwidth, the higher the resolution of the results. The question is: How important is that in the day-to-day troubleshooting of most electricians and engineers? It all depends on your applications.
