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 […]
Calibration
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, […]
Calibrators ease the DMM workload
The 5560A from Fluke Calibration lets you calibrate DMMs to 6½. Other models handle fewer digits.
Traceability and the hierarchy of calibration
Advances in the science of measurement are simplifying the task of accurately quantifying uncertainty. Michael Brown, Fluke Calibration Accurate measurements are critical to every aspect of our lives; that’s why metrology is the oldest science in the world. Our ability to understand the world around us depends on how well we can measure it. As […]
What to look for during instrument calibration
When you send an instrument to a calibration lab, what do you expect to happen? The comprehensive definition of calibration is a verification of instrument specifications by measuring actual performance using external lab standards, normally instruments, which have better performance than the thing they’re measuring and which are traceable to the International System of Units […]
