Engineers can use AI/ML to reduce test development time, analyze test data from manufacturing, automate visual inspection and calibration, and identify counterfeit components. Here’s how some do it. Testing takes too much time; just ask any engineering or production manager. Shortening test-development time can reduce time to market. Shortening production test time lowers manufacturing costs. […]

Flea market vintage test equipment, September 2024
The monthly “Flea at MIT” featured an abundance of test equipment. We even bought some.
How can I quantify a device’s nonlinearity? part 1
You can specify nonlinearity in parts per million or, especially for RF components, in terms of the 1-dB compression point or third-order intercept point.
What’s a half digit and are they all the same?
The most significant digit on a DMM’s display often doesn’t count 0 through 9.
Audio analyzer combines analog and digital domains
The APx516B from Audio Precision comes with built-in analog I/O and a slot that adds wired or wireless digital I/O. With so many of today’s devices having audio capabilities, engineeers designing wired or wireless audio into a device need to verify audio quality. Audio Precision, well known for its audio analyzers, has introduced the APx516 […]
How do I choose an electric motor, and how do I test it? part 4
You indeed can measure three-phase power in a motor with just two wattmeters. Part 3 of this FAQ concluded with a simplified diagram showing a test setup that included a programmable power supply, a motor under test, a mechanical load, a power analyzer, and host computer. The programmable power supply could simulate the AC line […]
Boost/single-ended primary inductance converter (SEPIC) controller for various automotive LED applications.
Spectrum Instrumentation has extended the M5i flagship series of high-speed PCIe digitizers, adding two new models with ultrawide bandwidths that go up to 4.7 GHz for -3 dB attenuation or even 5 GHz for -5 dB attenuation. The models M5i.3360-x16 and M5i.3367-x16 provide one and two channels respectively with prices starting from $27,990. Each card […]
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 […]
