Laser and light communications news

Light communications is hot in news now. Here are few headlines: LiFi 802.11bb standard uses light for in-room data transmission up to 224GB/s https://www.cnx-software.com/2023/07/14/lifi-802-11bb-wifi-standard-uses-light-for-in-room-data-transmission-up-to-224gb-s/ The 802.11bb WiFi-like standard, also called LiFi, was ratified in June 2023. It enables data transmission up to 224GB/s at a few meters range within a room using light instead of

Oscilloscope with a great history

IT’S A HUMBLE ‘SCOPE, BUT IT CHANGED OUR WORLD https://hackaday.com/2023/07/06/its-a-humble-scope-but-it-changed-our-world/ Now anyone seeking a connection with both Pong and the Apple II can have one of their very own if they have enough money because [Al Alcorn]’s Tektronix 465 oscilloscope is for sale. He’s the designer of the original Pong and used the instrument in

High voltage probe

A high voltage probe allows an ordinary voltmeter to measure voltages that would otherwise be too high to measure or even destructive. Typically normal multimeters are typically designed to measure voltage up to hundreds of volts or one kilovolt. If you need to measure higher voltage, you need to use a high voltage probe. A

What is low Z on multimeter?

What is low Z on multimeter? Dual impedance digital multimeters have feature to control the input impedance of the multimeter. LoZ stands for Low Impedance (Z). This feature presents a low impedance input to the circuit under test. A typical digital multimeter has typically around 10 megaohms input impedance, which loads the circuit being measured

4G on the moon soon

Can terrestrial networks can meet the communications needs of future space missions? Maybe. Nokia is planning to launch 4G internet on the moon later this year, an executive for the company said. It will be used within Nasa’s Artemis 1 mission, which aims to establish a human presence on the moon again (last time was
