The 5560A from Fluke Calibration lets you calibrate DMMs to 6½. Other models handle fewer digits.
Test and Measurement Tips
Untangling accuracy, precision, and resolution, Part 1: Basics
Accuracy, precision, and resolution are key parameters, each with a distinct meaning and implication with respect to system design and confidence. To the average person, terms such as accuracy and precision are somewhat interchangeable, and that’s fine. However, they have very specific and different meanings as well as design and test implications for scientists, engineers, […]
The perils of oscilloscope ground and power ground
Most electrical engineers probably are aware that connecting the ground connection for ordinary oscilloscope probes to the wrong part of an ac power line will invite a lot of trouble. Unfortunately the remedies sometimes employed to head off difficulties can cause their own woes. In a lab where I was once employed, the instrument carts […]
How to run video games on an oscilloscope
Spend enough time on YouTube and you’ll uncover numerous videos showing some kind of video game being played on an oscilloscope. The most popular game choices for these videos seem to be the old Doom and Quake games and Pong, the first real video game released in 1972. Perhaps the main reason for Doom’s popularity […]
Development chassis sports mix of VME64x, OpenVPX backplanes
An open-frame enclosure contains multiple configuration options utilizing VME and OpenVPX backplanes. With a vast array of standard VITA 65 profile and power and ground only (unrouted) OpenVPX backplanes available, Pixus can offer a wide range of solutions. Coupled with various standard VME/VME64x backplanes, the company can provide a mix of slot options in both […]
Source measure unit combines four-quadrant voltage/current source with 6.5-digit meter
The AIM-TTi SMU4000 Source Measure Unit Series integrates a fast and agile high-power, four-quadrant voltage/current source with advanced precise voltage/current meters as an all-in-one test solution. Precisely supplying positive and negative voltages, sourcing or sinking power, while simultaneously measuring both current and voltage, makes these instruments candidates for rapid I-V characterization. The PowerFlex autoranging design […]
Test gear checks out Wi-Fi 7 chipsets
An automated test solution checks out Broadcom Wi-Fi 7 chipsets, the industry’s first Wi-Fi 7 chipsets optimized for mobile handsets that also support simultaneous dual-band 2×2 IEEE 802.11be-compliant operation. Rohde & Schwarz collaborated with Broadcom to successfully verify the R&S CMP180 next generation wireless device test platform for R&D and production. The IEEE 802.11be amendment […]
Multi-instrument tester includes eight programmable benchtop instruments for common test procedures
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 […]
Solar array simulator for satellites mimics conditions in space
The new MP4300A Series Modular Solar Array Simulator (SAS) emulates the behavior of photovoltaic (PV) segments. The SAS solution simulates all conditions a craft or satellite will encounter in space with high fidelity. Launching solar-powered spacecraft or satellites is incredibly expensive, with little possibility of recovery or repair. These vehicles must have efficient and reliable […]
Set up automatically measures/reports environmental conditions for cable/harness testing
An automation-ready cable and harness test system now has an environmental sensor option incorporating the Dracal PTH200 sensor. Of particular interest to medical and defense applications, this option provides automatic measurement and reporting of environmental test conditions (temperature, relative humidity, pressure) alongside electrical function data for the cable, harness, or backplane under test. This option […]
