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 […]
Meters & Testers
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.
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 […]
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.
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. […]
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, […]
Back from a three-year hiatus, I’m covering test and measurement again. This time, it’s for EE World.
The 5560A from Fluke Calibration lets you calibrate DMMs to 6½. Other models handle fewer digits.
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 […]
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 […]
