When I was an electrical engineering student back in the 1970’s at the University of South Florida — go bulls! — two of my favorite classes were Control Systems and Analog Circuit Fundamentals. One reason I loved these classes so much was because we got to create Bode plots. I know, that sounds weird. I really enjoyed finding the theoretical poles…
It’s Scope Month, and you know what that means, oscilloscope giveaways! But this year we’re giving you even more chances to win.   How? This year Scope Month includes a scavenger hunt. We have hidden your favorite oscilloscope guru Daniel Bogdanoff all over the world (don’t worry, they’re just life-size cardboard cutouts). Your job? Find Daniel.…
Do you want to accurately measure signals with minimal effects from your oscilloscope probe? The oscilloscope probe is a critical link in the quest for accurate signal measurements. The probe is more than just a connection between the circuit under test and the oscilloscope. It can affect both your measurement results and the circuit under test.…
The second the probe is connected to your device your signal begins a grand journey to the center of the scope. It has to pass through five phases in order to complete its journey to the center, then back up to the surface. First the signal has to find its way to the front of the scope through the probe. Then, once it enters the scope, it has to…
Oscilloscopes have two primary modes of triggering: AUTO and NORMAL. However, NORMAL is not the normally used mode of triggering. AUTO is. The default trigger mode in all of today’s oscilloscopes is AUTO. There is a lot of confusion these days among oscilloscope users as to exactly when to use which mode of triggering. Let’s first define what…

When I hear someone say this and I ask “why,” the answer is nearly always “I need to measure how much power this thing is using”.  Based on this experience I have come to consider current probe use as synonymous with power measurements. Usually someone is trying to figure out how much power they are using or determine if the supply they have…
When you are testing a crystal oscillator circuit with an oscilloscope probe, the oscillator may stop oscillating or the waveform may be severely distorted. Why?   Every probe functions as an external circuit connected to the device under test. Each probe has its own input resistance, capacitance and inductance, imposing additional load to the…
Today is the day! Today is the day!! Why is today so important? I’m glad you asked. Well, for starters, it’s the first day of Scope Month! If you liked last year’s Scope Month, you’re going to love the 2017 version. During the entire month of March, we’re giving away 125 oscilloscopes – that’s more than 3x what we gave away last year. Make sure…
