When discussing total harmonic distortion (THD), the fundamental of the wave in question is known as the first harmonic. Quantifying THD, therefore, begins with the second harmonic. Theoretically, the number of harmonics is limited only by some maximum frequency based on minimum quantum wavelength. In reality, however, we are interested in a relatively small number […]
Software speeds double-pulse testing with AFGs
A new software plugin for the AFG31000 Arbitrary/Function Generator makes it possible to perform crucial double pulse testing in less than a minute, saving a significant amount of time when compared to alternative methods. With the new Double Pulse Test software, engineers can quickly define pulse parameters from a single window on the AFG31000’s large […]
Basic instrumentation for the electronics workbench
Engineers and technicians doing design, development, and testing have a wide range of instrumentation available for use on the test bench. So it might be useful to consider which instruments are considered the “basics” for the general case. Here are a few nominations along with the device properties that are generally considered “must-haves.” The unassuming […]
New approach to frequency analysis on oscilloscopes
It has often been the case that optimizing scope setting to display a detailed view of an FFT results in a time-domain view that is suboptimal. Not anymore. Gary Waldo, Tektronix The debugging of embedded systems often involves looking for clues that are hard to discover when examined one domain at a time. The ability […]
The difference between a pulse generator, a signal generator, an AFG, and an AWG
There are a variety of instruments available to generate electronic signals these days. They go by different names and provide different kinds of outputs. Differences between the various kinds of instrumentation aren’t always obvious, so here is a short primer. Signal generators make available at their outputs sinusoidal waveforms with a settable frequency or amplitude. […]
Setting up a serial or parallel bus in the Tektronix MDO3000 Series oscilloscope
The buttons that access digital functions in the Tektronix MDO3000 Series oscilloscope are grouped together near the bottom of the front panel, just above the analog ports and the Analog Channel One input. Nearby is an insulated cover over the digital input ports and the digital D15-0 button. You may wonder how it is possible […]
Working with the Tektronix AFG31000 Series arbitrary function generator
The Tektronix AFG31000 Series Function Generator can be used in conjunction with an oscilloscope to display the generated signals in one or two analog channels on a large LCD. Alternately, the AFG has smaller waveform displays with reduced resolution, nonetheless adequate for demonstrating the functionality of this powerful instrument. When initially powered up, the AFG […]
The difference between noise and jitter
Noise and jitter in electronics are closely related phenomena. Both are unwanted electrical energy that we mitigate where possible and otherwise work around. Weak signals are obscured by noise. No amount of filtering can reduce noise that is caused by fluctuations intrinsic to the signal being measured, but this noise can be partially eliminated by […]
Software simplifies scope-based automotive Ethernet testing
Two new software packages greatly simplify Automotive Ethernet testing, debug and Protocol Decode on Tektronix 5 and 6 Series mixed-signal oscilloscopes (MSO). Using the new Signal Separation software, engineers can now perform Automotive Ethernet testing without disrupting the ECU system or cutting the Ethernet cable to install a directional coupler, while the PAM3 analysis package […]
