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 […]
Flea market vintage test equipment, September 2024
The monthly “Flea at MIT” featured an abundance of test equipment. We even bought some.
4U high power supply delivers 45 kW for EV testing
Chroma announces the release of its next-generation bidirectional DC power supply, model 62450D-2000HL, delivering a game-changing single-unit power density of 45kW in a 4U high form factor. In an industry-first, the 62450D-2000HL enables one-key switching between two output ranges within a single unit, effectively providing the output range of two units in one. Users can […]
IMS 2024 roundup: test equipment
Washington, DC — The 2024 International Microwave Symposium took place here in June at the Walter E. Washington Convention Center. As always, RF/microwave/mmWave test equipment was all over the exhibit hall. Frequency-domain test equipment — spectrum analyzers, vector network analyzers, power meters, and signal generators — were, of course, dominant. Other equipment, such as oscilloscopes […]
