![]() ![]() Averaging acquisition mode should be used only with periodic signals and with a stable oscilloscope trigger. ![]() This mode should only be used under certain circumstances or you could get misinformation on the screen. Therefore, using averaging mode will help give you more insight into what your current waveform actually looks like. For example, clamp-on current probes are notoriously noisy. The main benefit of averaging acquisition mode is that it averages out the random noise on your signal this allows you to see just the underlying signal. Averaging mode takes multiple waveform captures and averages them together. A 100-kHz clock signal captured using normal acquisition mode.Īveraging acquisition mode is probably the second most commonly used mode. It’s a very safe mode to use, and has no significant caveats. It’s best to use normal acquisition mode for day-to-day debugging tasks because it gives a good general representation of your signal. The ADC samples and the scope decimates down to the desired number of points and plots the waveform. Normal acquisition mode is the default mode for oscilloscopes. The scope’s bandwidth is a specification that defines the front-end hardware’s ability to capture a signal’s frequency content. Sample rate is how fast the ADC acquires samples. It’s worth noting that sample rate is not the same as bandwidth. By varying the sample rate of the scope’s analog-to-digital converter (ADC) and selectively plotting or combining sample points, different characteristics of a signal can be observed. Learn how normal, averaging, and high resolution modes work, and when you should use each one.Īcquisition modes are finely tuned sampling algorithms that give you unique insights into your signal. Extracting the most confidence from your oscilloscope readings requires understanding the strengths and weaknesses of different acquisition modes. By using an ADC paired with a plotter instead of a sweep generator paired with a CRT, you can change how your signal is acquired. The movement from analog to digital oscilloscopes has opened up a new world of measurement opportunities for engineers. The awesome functionality-to-size ratio is due, in part, to the ATXMEGA32A4U microcontroller on board.This file type includes high-resolution graphics and schematics when applicable.ĭaniel Bogdanoff, Oscilloscope Product Manager, Keysight Technologies The scope itself obviously allows simultaneous sampling of analogue and digital signals but also has several advanced trigger modes, XY mode for plotting Lissajous patterns, phase differences or V/I curves, Spectrum Analyser with different windowing options and even an arbitrary waveform generator with sweep on all parameters. You can also connect it to your PC and use Gabotronics' XScopes software to control the device and view waveforms. The on-board graphic OLED matrix can display waveforms, measurements and menu systems. At only 1 x 1.6 inches, this oscilloscope can be plugged directly into a breadboard. The XMEGA Xprotolab is exactly that: The first ever mixed signal oscilloscope, logic analyser and arbitrary waveform generator in a DIP module. What you probably don’t imagine is a DIP package. When you think about a piece of equipment like a mixed signal oscilloscope you usually think of, well, a piece of equipment. ![]()
