The difference between Robert Bunsen’s burner and a gas stove
Jointly Robert Bunsen and Gustav Kirchhoff invented the spectroscope, which they used to identify spectra produced by sodium, lithium and potassium when they were heated to incandescence. This was possible only because previously with a lab assistant Bunsen had perfected a gas torch that did not emit interfering light. Their Bunsen burner has remained in […]
Instrument road test: The Liquid Instruments Moku:Pro
Liquid Instruments, an Australian company (there is also a U.S. office near San Diego), is offering a new diagnostic and product development tool that enhances the ability of laboratories and educators to see ever deeper into waveforms of interest. Previous instruments were Moku:Lab and Moku:Go. While these units were robust diagnostic engines, Moku:Pro puts it […]
Data logger features 1 kV isolation, 50 kHz sampling
A new and improved high-voltage, isolated DAQ called the Model DI-4730 builds on the widely used DI-730 series. Featuring up to 16-bit A/D resolution, stand-alone data logging capability and a channel expansion option, allowing the daisy chaining of the DI-4730 with other DI-4000 series products. The DI-4730 features eight analog inputs with programmable measurement ranges […]
Barcode scanner input option loads and runs electrical safety test sequences
A handheld barcode scanning feature is available for the advanced QT Enterprise PC-based Electrical Safety Software package. QT Enterprise software provides a clean and intuitive means for creating and modifying a virtually unlimited number of electrical safety testing procedures for use with Vitrek’s widely used V7x and 95x Series of high-performance Electrical Safety (hipot) Testers […]
Programmable dc supplies include wireless remote sense feature
The new Intelligent Laboratory Series (iLS) of programmable dc power supplies feature an industry-leading small footprint and high-power density. The iLS600, iLS600-R and iLS1500 sport programmable capability with best-in-class measurement accuracy and a patented wireless remote sense feature that significantly reduces noise in a wide range of test and measurement applications. Designed for both benchtop […]
When to measure conductivity instead of resistivity
Resistivity and its inverse, conductivity, are different from the more familiar metrics, resistance and its inverse, conductance. Resistivity is applicable to types of materials. For example, glass and carbon have specific resistivities whereas a particular carbon resistor of a given length, diameter and temperature has a specific resistance. In a nutshell, resistance is defined as […]
Battery pack test system handles up to 1.5 kV for automotive, industrial applications
The Scienlab SL1700A Series is the next generation battery pack test system for high voltage battery packs – up to 1,500 V for automotive and industrial application. Developers need vast labs with multiple test channels to develop batteries, but space and power supplies are limited. Keysight’s SL1700A Series utilizes new high voltage silicon carbide (SiC) […]
PXI/PXIe multiplexer module optimized for MIL-STD-1553 testing
A new PXI/PXIe multiplexer module is optimized for MIL-STD-1553 testing applications. With a differential bandwidth of 450 MHz—far exceeding the requirements of MIL-STD-1553—the model 40/42-739 is available in single or dual 4:1, 8:1 or 16:1 differential configurations. Using telecommunications-grade electromechanical relays, the 40/42-739 multiplexer has a minimal initial signal path resistance of less than 450 […]
PXI chassis sports two slots
NI’s first two-slot PXI chassis delivers a small, cost-effective package. Modular hardware like PXI enables a software-connected workflow to achieve better results. PXI hardware delivers openness, software options, modularity and I/O coverage for projects developing adaptive and scalable systems. PXI uses commercial PC-based PCI and PCI Express bus technology while combining rugged CompactPCI modular packaging, as […]
