Approaching the launch of the iPhone 12, we look at the internals of an old iPhone widely repurposed today as webcams, security cameras, and iPods. As we write this, the new lineup of iPhone releases expected this fall is said to include models able to work at 5G speeds as well as a new case […]
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 […]
PC-based VNA handles signals out to 8.5 GHz
The newly announced PicoVNA 108 comes in the same low-cost, small-footprint and portable format as the widely used PicoVNA106 6 GHz instrument. The PicoVNA 108 can see out further to 8.5 GHz and it can see down deeper to –124 dB. It provides new “save on trigger” synchronization for multiple measurements, for example, with changing […]
High-energy-storage, pulse-discharge capacitors handle repetitive high-energy/high-voltage charge/discharge apps
A major product expansion of standard and custom high energy storage, pulse-discharge capacitors is designed for handling applications requiring repetitive high energy and high voltage charge/discharge cycles. The capacitor technology is based on a film-dielectric with self-healing metalized or high-current discrete-foil electrodes, depending upon application requirements. There are both dry and oil-impregnated types, offered with […]
Optical transceiver test platform reduces test time, accurately measures PAM4 optical signals
The new 8 Series sampling platform is a disaggregated modular instrument series boasting parallel acquisition, with up to four channels per mainframe and the highest measurement accuracy for PAM4 optical signals on multiple inputs simultaneously. The 8 Series consists of the TSO820 Sampling Oscilloscope Mainframe, optical sampling modules, and TSOVu, a new software platform that […]
On the energy storage front: Structural batteries, capacitors with ultra-high energy density
The high interest in more economical energy storage these days yields a continual stream of news about advances in battery chemistry. Here are a couple recent developments of particular note: Capacitors with a high energy density — Capacitors generally have low energy densities relative to batteries or fuel cells. Researchers at the Dept. of Energy’s […]
Data streaming/visualization platform works with logging, 6.5-digit DMMs
A native integration mates the Keithley DAQ6510 and DMM6500 instruments with Initial State, an loT dashboard for data streaming and visualization for world-class, remote data access. Keithley and Initial State, both Tektronix companies, collaborated to integrate Initial State’s data streaming and visualization platform with the Keithley graphical DAQ6510 and DMM6500. This integration gives a DAQ6510/DMM6500 […]
Chip sockets provide 75-GHz bandwidth for 0.25-mm-pitch devices
A new 0.25-pitch socket uses a high-performance elastomer capable of 75 GHz with low inductance and capable of working in a wide temperature range. The 1280 WLCSP socket is designed for a 10×8-mm package size and operates at bandwidths up to 75 GHz with less than 1 dB of insertion loss. The contact resistance is […]
RF hybrid couplers operate up to 40 GHz
A hybrid coupler line expansion consists of 21 new models with a high-frequency operating range of up to 40 GHz for wide band applications. These coaxial designs feature SMA and 2.92-mm connectors. They are candidates for RF applications that require an even split of input and output ports with 90° or 180° phase shifts while […]
Shedding light on how much UV-C you need for disinfection
The idea of using UV-C light to kill the COVID-19 virus by disrupting its RNA has captured the imagination of many in the technical community. Unfortunately, important application details about factors such as necessary exposure time and intensity levels may be hard to discern, particularly for those who are new to the technology. A complicating […]
