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. […]

Making sense of test circuits with Kirchhoff’s laws: part 2
In part 1 of this series, we looked at ways to simplify resistor networks by identifying series and parallel combinations of resistors. We closed with a look at a version of the Wheatstone bridge, such as the one in Figure 1. Although it has only five resistors, not one of them is in series or […]
Oscilloscope features fast data transfer, 10-bit ADC
The Series 7 DPO oscilloscope from Tektronix is the company’s first new high-end model in years. It uses an optical port to transfer data faster than anything we’ve seen. Oscilloscope announcements come often, but most are for low-end. And midrange models. The Series 7 from Tektronix datasheet clearly fits into the high end, though it’s […]
R&S digital multimeters feature 5.5 and 6.5 digits with triple displays
The UDS series from Rohde & Schwarz provides the company with a significant upgrade and place it against top competitors. Digital multimeters (DMMs) are a measurement staple, sitting alongside oscilloscopes, power supplies, and waveform generators on just about every engineer’s bench. You may not think of Rohde & Schwarz as a major competitor in the […]
Teardown: HP 8112A pulse generator
This 50 MHz pulse generator was built as solid as a rock. It’s almost all metal. We take the unit completely apart and look at it from a system and board level. On a visit to the MIT swapfest in 2024, I came across an HP 8112A 50 MHz pulse generator. For $20, I brought […]
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 […]
Download our 2024 T&M Tech Toolbox
Everything needs testing and testing needs measurement. That’s why we assembled a collection of articles from Test & Measurement Tips into the 2024 T&M Tech Toolbox, a 56-page e-book in PDF format. We took some of the top articles from our recent archives to provide you with information that can help you with your job. […]
Testing platform now includes 1.6Tb/s test module for high-speed ML/AI applications
Viavi Solutions Inc. announced the first solution to address the testing and validation needs of the emerging 1.6Tb/s ecosystem based on 224G SERDES. This new testing module, the ONE-1600, is the latest addition to the company’s growing ONE LabPro platform, which also includes the HSE-800 800Gb/s test module. Designed to accommodate OSFP1600 and QSFP-DD1600 form factors, […]
Free online tools perform RF calculations
RF engineers often need to calculate parameters such as VSWR and RLC networks. Ampleon provides these and other free RF design tools for you to use. Ampleon, a maker of RF components, provides engineers with a free RF online tools page where you can find four sets of useful tools. Each of the four tools […]
Data-acquisition recorder gets 1500 VDC module
B+K precision adds a 4-channel, ±1500 VDC input module to its DAS1800 data recorder. Today’s electric vehicles operate at voltages approaching 1000 VDC, engineers need to monitor and record those voltages during tests. to that end, B+K Precision has added the D18-HVM4 high-voltage, 4-channel input module to its DAS1800 modular data recorder. The D18-HVM4 adds […]
