As a follow-on to the topic of dealing with noise, let’s look at the opposite end of the spectrum (literally). In the previous post, we started out looking at noise coupling from an inexpensive power ...

With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

The Rigol DS1000 series of oscilloscopes are popular with hobbyists for good reason: they provide decent specs at a low price. However, their spectrum analysis abilities are lacking. While these ...

Fig 1. The Tektronix MDO4000 combines an oscilloscope and a spectrum analyser in one tool, enabling the capture of time-correlated analogue, digital, and RF signals across four analogue channels, 16 ...

Let’s say a corporate engineer or a consultant is coming to your station to diagnose and repair a problem using an RF spectrum analyzer. This would be a great time to schedule a meeting with your ...

Back in the 1960s, when I started working in radio broadcast engineering, an oscilloscope was my “eye” on what was happening with equipment. That tool served me well and is still in daily use in my ...

Modern embedded system designs present challenges for EMI testing and troubleshooting that didn’t exist years ago. These challenges include switching power supplies, high speed system clocks and data ...
