These basic RF measurements often uncover system problems in wired and wireless communications. If you observe a signal traveling from a source to a load through a passive system of some sort, you will notice that the signal attenuates by the time it reaches the load, and you will also notice that some of the […]

How to run video games on an oscilloscope
Spend enough time on YouTube and you’ll uncover numerous videos showing some kind of video game being played on an oscilloscope. The most popular game choices for these videos seem to be the old Doom and Quake games and Pong, the first real video game released in 1972. Perhaps the main reason for Doom’s popularity […]
Margin tester checks out PCIe Gen 3, Gen 4 designs
The new TMT4 Margin Tester breaks conventions of PCIe testing, delivering fast test times. Plug-and-play set up and easy-to-use interface combine to deliver in minutes results that, until now, required hours or even days of set up and testing, often stretching costs to seven figures. “TMT4 Margin Tester is the latest example of how Tektronix […]

Debugging digital and analog signals with cross-domain analysis
Multi-domain signal analysis is blurring the line between real-time oscilloscopes and real-time spectrum and signal analyzers. Fernando Gomez, Tektronix Inc. Multi-domain signal analysis is enabled by advanced oscilloscope features such as 12-bit ADC, digital down conversion (DDC), and flexible channel inputs where each can be either analog or digital. As Signal Integrity (SI) and Power […]
From resistors to antique radios, swapfests have it all
Scope-based diagnosis of three-phase motor drives
Ordinary oscilloscopes can view basic parameters in modern motor drives, but operational insights generally require specialized power analyzers. Variable frequency drives (VFD) generate carefully controlled pulse-width modulated (PWM) waveforms to modulate the speed of industrial ac motors. Often, the motors involved are three phase. Three-phase ac induction motors (ACIMs) are widely used though they are […]
EMI testing for IoT transceivers
A few oscilloscope measurements can give insight into sources of electromagnetic interference that garble the operation of wireless IoT devices. Examine a typical wireless device with an internet of things connection and you’ll likely find multiple RF receivers squeezed together in close proximity onto a circuit board. Cramped quarters characterize modern IoT electronics, so sensitive […]
