Isolated current probes eliminate ground loops
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 […]
RF-isolated current probe achieves 140 dB CMRR at DC
Tektronix has released two new power measurement devices: the TICP Series IsoVu isolated current probes and the EA-PSB 20000 Triple series power supply. The TICP Series probes utilize RF isolation technology for current measurements across voltage systems. The probes achieve 140 dB common-mode rejection ratio (CMRR) at DC and up to 90 dB at 1 […]
Flea market vintage test equipment, September 2024
The monthly “Flea at MIT” featured an abundance of test equipment. We even bought some.
OFC 2024: How AI and silicon photonics will drive network test
EE World spoke with Sarah Boen, Director of Technology and ASIC Strategy at Tektronix, who spoke at a panel session on how AI and silicon photonics are changing networks and the challenges facing test engineers and reliability engineers.
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 […]
AOC 2023: Exhibits show the latest in military wireless
Washington — The Association of Old Crows (AOC) held its 60th annual convention in Washington during the week of December 11, 2023. EE World was there on December 12. Here is some of what we saw in the exhibit hall. AOC is a defense-oriented conference that focuses on military wireless communications. In addition to product […]
Product tryout: Tektronix 4 Series B oscilloscope
EE World gets its hands dirty on the latest Tektronix 4 Series B oscilloscope. So many features, so little time. When Tektronix gave the press a preview of the 4 Series B 12-bit mixed-signal oscilloscope and TekScope software, I asked to try the software. Days later, the real thing arrived in a transit case. Fortunately […]
Free drivers connect Tektronix instruments to Python
Tektronix announced an open-source Python instrument driver package for the company’s test instruments. Available at no cost, the package provides you with a native Python user experience for instrument automation. With integration into daily workflows and utilizing it with a preferred Integrated Development Environment (IDE), engineers use features such as auto-complete, precise type hinting, comprehensive […]
What are the important specifications of USB oscilloscopes: Part 2?
USB oscilloscopes can be highly useful design, development, and testing tools. Like many tools, they need to be optimized for specific use cases. This second FAQ looks at specifications for triggering, input ranges and probes, zooming, and control software. Part 1 considered specifications for the number and types of channels, bandwidth, sample rate, refresh rate, […]
