How to locate EMI emissions with near-field probes: Part 1
Near-field probes let you find the sources of near-field and far-field EMI that ruin your design, and your day. You don’t need to know Maxwell’s Equations to troubleshoot your designs.
The factors of accurate measurements
All measurements need reliable, accurate equipment that’s traceable to worldwide standards. Without that, measurements have no value. From ensuring product quality in a factory to safety to letting every individual use a computer or phone, accurate measurements are critical in every aspect of our lives. In the automotive industry, accurate measurements of components and the […]
EE World’s 2023 T&M Handbook is now available
For 2023, the digital version features 11 technical articles that cover test from signal integrity on the bench to automated test on the production floor.
What is de-embedding and how do I perform it (part 1)?
It’s a tenet of the test-and-measurement industry that you should concentrate on looking for defects in your device under test (DUT) — not in your test equipment. Figure 1 illustrates a common problem. An instrument presents an incorrect reading; in this case, an LRC meter or multimeter presents a resistance reading that’s about 5% low. […]
Functional tester covers bench, production, and service applications
The midUTS from Bloomy contains a multimeter, data-acquisition, switching, and power supplies for testing boards and systems. Automating tests — whether for bench testing new designs, in production, or for service — increases productivity but comes at a price. If you’re going to build an automated test system all yourself, expect to specify the instrumentation, […]
I’ve got the measurement blues again
Back from a three-year hiatus, I’m covering test and measurement again. This time, it’s for EE World.
Calibrators ease the DMM workload
The 5560A from Fluke Calibration lets you calibrate DMMs to 6½. Other models handle fewer digits.
Multi-instrument tester includes eight programmable benchtop instruments for common test procedures
The ABI Multiple Instrument Station MIS4 Test Station is an all-in-one testing tool that combines in a compact case all commonly required test instruments in one compact and programmable hardware module. Controlled by ABI’s sophisticated SYSTEM 8 Ultimate PC software with a simple yet programmable operator interface, the MIS4 combines eight laboratory instruments: a three-channel […]
What’s a ring tester and why do you need one?
If you one day find yourself with a transformer that might or might not have a shorted winding, your first inclination for verifying your suspicions might be to find an inductance meter. The problem with powering up an inductance meter for this situation is that the inductance of a transformer containing a shorted turn might […]
