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 2024: Test equipment
Test equipment is everywhere. Every trade show has it regardless of the focus. Power is no exception. At APEC 2024, EE World visited several booths displaying test equipment: meters, oscilloscopes, source-measure units (SMUs), bench power supplies, and electronic loads. The photos and videos below highlight what we saw, presented in alphabetical order by company. In […]
How to use remote sensing for DC programmable power supplies
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 […]
21-slot PXI chassis features 20 hybrid slots
The 42-927 PXI chassis from Pickering Interfaces saves test-rack space by accepting up to 20 PXI or PXIe instruments and switch cards. No matter how many instruments they hold, large, automated test systems always take up too much floor space. While test racks may have increased in density since the PXI bus was introduced in […]
What is GPIB and is it obsolete?
The bus, codified as the IEEE 488 standard, continues to find use in legacy test-system upgrades and in calibration labs. The General-Purpose Interface Bus (GPIB) began life as the Hewlett-Packard Interface Bus (HP-IB). Hewlett-Packard, whose electronic test-and-measurement business has evolved into today’s Keysight Technologies, created the interface in the 1960s to connect multiple instruments in […]
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 […]
Bench power supply provides up to 80 V or 50 A at 750 W
The Aim-TTi QPX750SP 750-W single-output dc power supply can provide voltages between 80 V at 9.4 A and 12 V at 50 A with a maximum resolution of 0.1 mV. This laboratory power supply is designed to provide a flexible choice of voltage and current to meet multiple application needs. It is housed in a […]
Programmable ac sources provide low THD in 3U form factor
The 9830B Series programmable ac power sources provide high performance and low total harmonic distortion in a 3U form factor. Offering 2,000 VA or 3,000 VA models, the new 9832B and 9833B provide the ability to connect three instruments to create a three-phase ac power source using the convenient three-phase kit (TL983P-KIT) option. The adapters […]
Regenerative power supplies handle up to 20 kW and 2,000 V
The RP7900 Series of regenerative power supplies has expanded with the introduction of two new bidirectional, regenerative dc power supplies providing integrated safety features that protect people and devices under test (DUT). The regenerative design of the new models enables the energy normally consumed to be returned to the grid cleanly, saving costs associated with […]
Benchtop power supplies provide four 80-A channels
The new R&S NGP800 power supply series includes two and four-channel models and further extends the functions and performance available for dc power provided by Rohde & Schwarz. For any test and measurement application requiring up to four independent dc power supplies with full flexibility, full functionality, full safety, and full connectivity, the R&S NGP800 […]
