Oscilloscopes are very useful tools in the electronics lab. There have been many varieties over the years, with a wide range of capabilities. Through the narrative below, we will explore some of the differences, capabilities, and short comings of oscilloscopes. Basic Oscilloscope Types: There have been three basic types oscilloscopes available over the years. Analog: [...]
Modern communication systems are typically based on a framework of channels, where the frequency spectrum is divided into channels of a defined bandwidth and each signal is assigned to a particular channel. This is analogous to a highway system being divided into lanes. On a highway, it is undesirable for a car to cross into [...]
The Department of Defense (DoD) purchases a vast array of electronic and electrical devices that must be integrated into various platforms with many other devices and function without degraded performance (electromagnetic susceptibility), and conversely, must function without causing degradation of performance for other devices (electromagnetic emissions). Similarly, electromagnetic interference (EMI) is a commonly used term [...]
Without additional information, a statement that a product is MIL-STD-810 certified or a requirement that a product be developed to meet MIL-STD-810 does not provide meaningful information about the environmental resiliency of a product. MIL-STD-810 is a test method standard that defines the environmental test procedures and engineering considerations for the design of a product. [...]
Product testing can consume an inordinate amount of time and resources, slowing the time to market. Traditional technician-on-the-bench testing can take up to two weeks to fully characterize a product such as an RF power amplifier (PA). It’s a long, tedious, and repetitive process. It’s costly as well – the cost of manpower and the [...]
