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 […]
Calibration
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 […]
Test data analysis software includes Python interface, supports multi-core PC parallel processing
The new version of data analysis software imc FAMOS 2022 from manufacturer imc Test & Measurement, a brand of Axiometrix Solutions, now integrates a Python interface and supports parallel processing for modern multi-core PC architectures. imc FAMOS offers professional tools for the visualization and analysis of test and measurement data from a variety of data […]
Automotive data logger captures multiple data streams simultaneously
The X2E XORAYA Z7 Automotive Datalogger can record data from multiple different automotive bus systems simultaneously. All data is logged with a precise, central timestamp with 100-nsec resolution and either saved on the internal SSD or transferred to an external computer system via Ethernet. Optionally, the logged data can be stored on a XORAYA external […]
Dual-channel digitizers provide synchronous 3.2 GS/sec, 12-bit sampling on each channel
A new dual-channel digitizer provides synchronous 3.2 GS/sec, 12-bit sampling on each channel. This means no data needs to be lost, even when the card is acquiring data with both channels running at their maximum sampling rate. The ultrafast bus allows all the data to be transferred directly to PC memory for storage, or even […]
