The Ethernet computer networking protocol is used in local area networks, metropolitan area networks and wide area networks. While the term is often used to distinguish wired data transmissions from Wi-Fi, both use parallel protocol details, notably 48-bit MAC address and Ethernet frame format. Actually, Wi-Fi is Ethernet over a different medium. There are a […]
Cathode ray tube vs. flat screen displays in oscilloscopes
Prior to the digital revolution in electronic instrumentation, oscilloscopes displayed waveforms on cathode ray tube screens. Modern digital oscilloscopes universally have flat screens. The flat screen is light, thin, consumes far less energy, and is less expensive to manufacture. All agree that it is a great improvement. The one advantage of CRT technology is that […]
Economical scope offers 1 GHz bandwidth, 5 GS/sec sample rate

Basics of active and differential scope probes
By far the most used oscilloscope probes are the passive 10:1 attenuation probe. It is appropriate when the frequency of the signal under investigation is less than 600 MHz. Impedance matching from the probe tip to channel input port is critical. A mismatch gives rise to reflections, collisions and loss of data. At dc to […]
