Dave investigates two very serious issues with jitter on the Rigol DS1000Z series oscilloscopes, including the DS1104Z and new DS1054Z Some sort of modulated sampling/trigger jitter problem at 5 microsecond intervals (the “5us jitter problem”). And severe jitter with the AC coupled trigger mode, a problem which is also present on the DS2000 series scopes

In the world of electronic components, there are many devices out there that do their job well and reliably, but are almost never heard of – even though they may be vital to equipment that plays a role in our technology-driven lives. The radio frequency (RF) circulator is just such a device: it has simply

In a serious case of out-of-the-box thinking, a design team at Roost in Sunnyvale California have come up with a method to add Wi-Fi connectivity to your old smoke or carbon monoxide alarm by just swapping batteries. Your smoke detector uses a 9 V PP3-type battery right? The new Roost battery contains 9 V lithium

While TFTs have been the mainstay of displays for years, OLEDs are becoming more prevalent as their price drops due to the phenomenal increase in quality from TFT to OLED technology. We received this demo board from Newhaven that effectively illustrates side by side the differences between TFT and OLED technology, using a 1.69 inch

Electrical energy is normally generated through heat, motion, nuclear transformation, or chemical reactions, but now scientists at VTT Technical Research Center of Finland have devised a new method that involves mechanical vibrations. They figured out how to “harvest” the vibrational energy that occurs naturally when two surfaces with different work functions are connected via electrodes,
New technique for generating electricity from mechanical vibrations Continue Reading
Morse code is used in telecommunication; it is a method of transmitting and receiving coded information. Each character (letter or numeral) is coded/represented by a unique sequence of dots and dashes. Compared to voice, Morse code is less sensitive to poor signal conditions, yet still comprehensible to humans without a decoding device, therefore, a useful
