Contending with Windows 10’s retirement: part 1
The discontinuance of tech support and free security patches presents challenges to users of legacy Windows 10-based test-and-measurement systems. The test-and-measurement industry has long leveraged consumer technology to take advantage of economies of scale and lower costs. Consequently, it’s … [Read More...] about Contending with Windows 10’s retirement: part 1
EMI: what it is and how to keep it in check
Electromagnetic Interference (EMI) is essentially invisible noise or pollution. It is unwanted electromagnetic energy generated by one electronic device that disrupts the normal operation of another nearby device. This FAQ will explain what an EMI is and what are the ways to prevent it. This … [Read More...] about EMI: what it is and how to keep it in check
Review: Picotest J2150B comb injector
This handy tool lets you test active and passive components at frequencies up to 3 GHz. I tried an early unit, using it for radiated and conducted EMI emissions testing. After almost ten years, Picotest has launched a new version of its Harmonic Comb Injector (generator). The J2150B ($495) is one … [Read More...] about Review: Picotest J2150B comb injector
Getting the most from your oscilloscope: part 3
Built-in math operations enable your scope to calculate and display measurement results. In part 1 of this series, we looked at the features oscilloscopes have offered for the past three-quarters of a century. In part 2, we looked at some of the unique features of modern digital scopes. In this … [Read More...] about Getting the most from your oscilloscope: part 3
Get the most from your oscilloscope: part 2
Modern scopes add a variety of new measurement and math features to the vertical, horizontal, and trigger controls used over a span of decades. In part 1 of this series, we looked at the features, such as the vertical, horizontal, and trigger controls that have appeared on oscilloscopes since the … [Read More...] about Get the most from your oscilloscope: part 2
Get the most from your oscilloscope: part 1
Oscilloscope technology has evolved from electromechanical assistance for hand-plotting to the development of full-featured automated digital instruments. The oscilloscope is an invaluable instrument that provides engineers with a picture of how signals inside their circuits behave. Today, they … [Read More...] about Get the most from your oscilloscope: part 1
How to choose analog-signal-chain components: part 5
Transimpedance and transconductance op amps convert currents to voltages and voltages to currents. We concluded part 4 of this series with a look at the instrumentation amplifier. Like the other op-amps and filter circuits we have so far described, the instrumentation amp is a voltage-input, … [Read More...] about How to choose analog-signal-chain components: part 5
How to choose analog-signal-chain components: part 4
Op amps find use in second-order filters and instrumentation amplifiers. In part 3 of this series, we described using the op amp to build some single-pole filters. Q: How do we build higher-order filters? A: Figure 1 shows one approach to a low-pass filter using the Sallen-Key topology. … [Read More...] about How to choose analog-signal-chain components: part 4
How to choose analog-signal-chain components: part 3
Use op amps, resistors, and capacitors to build high-pass, low-pass, and bandpass filters. In part 1 of this series, we looked at a noisy signal and discussed why it might be better to use an analog filter instead of a digital filter. Then, in part 2, we looked at the operational amplifier (op … [Read More...] about How to choose analog-signal-chain components: part 3
Do you need a real time oscilloscope or a sampling oscilloscope?
Real-time oscilloscopes capture a signal in a single pass, while sampling oscilloscopes, sometimes called digital communication analyzers or equivalent-time sampling oscilloscopes, take multiple samples over several periods of a signal, allowing for a slower sampling rate and potentially higher … [Read More...] about Do you need a real time oscilloscope or a sampling oscilloscope?

What is the importance of resolution in an oscilloscope?
When looking at the oscilloscope feature of a multi-instrument device or when comparing two benchtop oscilloscopes, the first specifications that we look at are the bandwidth and sample rate. While these are incredibly important specs, often most design work is done well within the limits of most products and the more critical specification to consider is resolution. Did you know that while most […]
