There came a time when high-speed electronic circuits reached speeds that required engineers to analyze the design for signal integrity (SI), power integrity (PI), and electromagnetic compatibility (EMC). Prior to that time, dedicated experts in separate teams focused primarily on their main specialty. The result: lengthy product review cycles when subsequent teams from these disciplines […]
Power supplies
Modular DC analyzer sources, sinks, and measures
The IT2705 mainframe and modules let you configure up to eight channels with modules that provide loads, sources, and SMUs. Test power supplies, batteries, IoT devices, medical devices, and so on. As powering circuits and systems get more complex, you often need to source, sink, and measure DC power for more than just DC levels. […]

AMETEK Programmable Power has appointed Transcat, Inc. as its exclusive distributor, calibration partner and rental provider for programmable power and test systems across the United States and South America. Under the agreement, Transcat will supply AMETEK’s AC/DC power supplies, electronic loads, power subsystems and compliance test solutions under the Sorensen, Elgar and California Instruments brands, […]
Tektronix event highlights precision measurements
At “Precision Unveiled,” Tektronix gave attendees a look at the future and displayed some current test equipment. Raleigh, NC, October 28, 2025 — Tektronix, well known for oscilloscopes and more recently power sources and power measurements through its acquisitions of Keithley and EA Elektro Automatic, hosted an event at the North Carolina Museum of Art. […]
PXI/PXIe battery simulators automate BMS testing
Pickering Interfaces has added two PXI and two PXIe battery simulators to its line of PXI test modules. The 41-754 (PXI) and 43-754 (PXIe) battery simulators are both available in 2-channel or 4-channel versions that can supply from 1 V to 8 V, 5 A per channel. The channels are fully isolated from ground and […]
Power distribution unit provides AC and 24 VDC to automated test racks
nVent Electric plc recently announced the U.S. launch of the nVent SCHROFF Rack Safety Plus power distribution unit (PDU), an innovative safety solution designed for both partially and fully automated test systems. As a UL Certified plug-and-play solution, the nVent Rack Safety Plus PDU with E-STOP reduces lead times and costs, and eliminates risks. Choose one […]
Phone chargers produce EMI: We compared four
The switching power supplies that regulate output voltage produce radiated emissions. Our tests compare waveforms that give clues as to how the chargers operate.
APEC 2025 test equipment: power sources and loads
Powering electronic devices requires the testing of power supply and charging circuits, battery management systems (BMSs), and battery cells. Many of these circuits require voltage, current, and power measurements, plus numerous others. Oscilloscopes and probes let you see the waveforms in power-delivery circuits, but the circuits themselves may need simulated batteries and simulated loads. That’s […]
APEC 2025 test equipment: oscilloscopes and probes
Oscilloscopes and probes play a vital role for engineers designing and testing power electronics. Delivering electrical power to analog and digital circuits and systems is more than just DC measurements. That’s because nearly all power-converter circuits use switching techniques to maximize efficiency. Silicon carbide (SiC and gallium nitride (GaN) transistors, with their higher voltage and […]
Design World presents the 2024 LEAP Awards Winners: Test & Measurement
In its seventh year, Design World’s LEAP Awards showcase the best engineering innovations across several design categories. This wouldn’t be possible without the commitment and support of the engineering community. The editorial team assembles OEM design engineers and academics each year to create an independent judging panel. Below is their selection for this year’s LEAP […]
