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 ...

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 ...

Oscilloscope bandwidth is a tricky thing. A 100 MHz scope will have a defined attenuation (70%) of a 100 MHz sine wave. That’s not really the whole picture, though, because we aren’t always measuring ...

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’ ...

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 ...

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 ...
