A hardware device or server software that captures packets transmitted in a network for routine inspection and problem detection. Also called a "sniffer," "packet sniffer," "packet analyzer," "packet ...

In today’s world, it seems that more of the people I run across do not feel they need — or, more accurately, don’t understand why they need — a protocol analyzer for their network. In the old days ...

When analyzing transistors, there is a finite allowable signal level that provides accurate results, which is due to a phenomenon related to the large signal effects of semiconductor junctions. When ...

With the acceleration of Internet of Things (IoT) devices and the proliferation of RF and wireless products, there is a growing need for RF measurement expertise and affordable RF test instrumentation ...

This presentation covers the principles of measuring high-frequency electrical networks with network analyzers. You will learn what kinds of measurements are made with network analyzers, and how they ...

[Steven Merrifield] built his own Scalar Network Analyzer and it’s a beauty! [Steve]’s SNA has a digital pinout matching a Raspberry Pi, but any GPIO could be used to operate the device and retrieve ...

With vector network analyzers, the commercial offerings seem to come in two flavors: relatively inexpensive but limited capabilities, and full-featured but scary expensive. There doesn’t seem to be ...
