Modular 4-channel power supply mounts in a test rack

March 10, 2025 By Redding Traiger Leave a Comment

B&K Precision announces the MPS Series. This series delivers up to four output channels and 1200 W of power in a compact 1U mainframe. Users can configure a customized 1-to-4 channel DC power system by selecting from eight interchangeable modules. The modules support various voltage/current output ratings and are capable of generating 100 W (multi-range) […]

Isolated current probes eliminate ground loops

November 15, 2024 By Martin Rowe Leave a Comment

Tektronix IsoVue Isolated current probe

IsoVu isolated current probes from Tektronix isolate oscilloscopes from circuits used for EVs, motors, and power converters. Trying to make shunt-based current measurements with a typical oscilloscope probe is essentially impossible. That’s because one side of the probe connects to ground through the instrument. Using an ungrounded power cord is anything but safe. Differential probes […]

How to determine noise figure: part 2

November 13, 2024 By Rick Nelson Leave a Comment

The relationship between noise and temperature prompted a precursor of the IEEE to promulgate an alternative definition of noise figure in 1959. In part 1 of this series, we described the work of the Danish-American radio engineer Harald Friis, who described noise factor F of a device or system as the ratio of the input-power […]

How to use remote sensing for DC programmable power supplies

January 15, 2024 By Connor Peck, EA Elektro-Automatic Leave a Comment

In this FAQ, you’ll learn how to know if your test application needs sensing and how to properly wire a power supply to a load. Calibrating certain sensing circuits, such as those used in electric vehicles (EVs), is critical to get right. An inaccurate calibration of an automotive battery monitoring circuit could, for example, allow […]

What are the critical measurements in satellite uplinks and downlinks?

May 8, 2023 By Bob Buxton, Wireless Telecom Group Leave a Comment

Noise measurement, LO substitution, receiver stress testing, power measurement, CCDF and PAPR characterization, and antenna-pattern measurement play critical roles in link budget, bit-error rate, and SNR requirements.

Lasers and how to measure their output

June 26, 2020 By David Herres 2 Comments

laser power meters

Laser is an acronym for light amplification by stimulated emission of radiation. Lasers, of course, started out as comprised of discrete components. The most basic laser consists of a cylinder containing the lasing medium, a material that emits light when exposed to an outside source of energy. The gain medium can be gas, liquid, solid […]
