Digital signal processors (DSPs) have been improving oscilloscope performance for over 10 years. DSPs were first used in scopes for sinx/x interpolation, where the DSP added points between samples to ...

The scopes’ improved performance is attributable in part to a second-generation silicon-germanium (SiGe) chipset that not only provides the increased bandwidth, but also improves the earlier scopes’ ...

I’ve been working on some materials for students recently, and this forced me to think about the way bandwidth is specified on oscilloscopes. At first glance, a specification such as bandwidth seems ...

The oscilloscope is an essential tool of any electronics bench, and it is also an instrument whose capabilities have expanded exponentially over the decades. Your entirely analogue CRT ‘scope of a few ...

A few weeks ago we published an article on the newly released Keysight 1000X, an oscilloscope that marks Keysight’s late but welcome entry into the hacker-centric entry-level market. Understandably, ...

Over the past couple of years, a quiet war has erupted among the major oscilloscope manufacturers. No blood has been shed—yet—but a lot of engineering blood, sweat, and tears have surely been expended ...

• Basic scopes consist of five basic functions: the display, the vertical inputs, the horizontal input, the time base, and the trigger. It’s said a picture is worth a thousand words. The truth of that ...
