The DAQ3120 from B+K Precision lets you install up to three measurement modules to create a custom system for your bench. Most engineers have a digital multimeter (DMM) for basic measurements such as voltage, current, and resistance. Sometimes, however, you need the flexibility to add channels and log measurements without or without a computer. That’s […]

APEC 2025 test equipment: power sources and loads
Powering electronic devices requires the testing of power supply and charging circuits, battery management systems (BMSs), and battery cells. Many of these circuits require voltage, current, and power measurements, plus numerous others. Oscilloscopes and probes let you see the waveforms in power-delivery circuits, but the circuits themselves may need simulated batteries and simulated loads. That’s […]
Ethernet/LXI digitizers feature 12-bit resolution and up to 4.7 GHz bandwidth
Spectrum Instrumentation has introduced seven new digitizers in the DN2.33x series for signal acquisition and analysis in the GHz range. The devices connect via Ethernet/LXI interface to computers or networks and are designed for both R&D and industrial applications. The DN2.33x series digitizers utilize ADC technology with sampling rates between 3.2 GS/s and 10 GS/s, […]
USB DAQ system reaches 20-bit resolution
The mioDAQ from NI has two 20-bit and two 16-bit flavors. Analog outputs come with two or four, with 16-bit DIO and counters. USB data-acquisition (DAQ) devices have been on the market for many years and come in many varieties. What makes the mioDAQ series from NI different is its 20-bit vertical resolution on two […]
Calibrator automates oscilloscope calibrations on four channels
Fluke’s 9500C oscilloscope calibrator with remote heads streamlines oscilloscope calibration from the front panel and through PC software.
Emerson acquires NI: There goes another one
NI will now join the long list of T and M companies whose names we’ll see only online, on eBay, and at electronics flea markets. Product names such as LabVIEW should live on.
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 GPIB and is it obsolete?
The bus, codified as the IEEE 488 standard, continues to find use in legacy test-system upgrades and in calibration labs. The General-Purpose Interface Bus (GPIB) began life as the Hewlett-Packard Interface Bus (HP-IB). Hewlett-Packard, whose electronic test-and-measurement business has evolved into today’s Keysight Technologies, created the interface in the 1960s to connect multiple instruments in […]
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, […]
