digital signal analyzer
1Vector signal analyzer — The vector signal analyzer (VSA) is a powerful tool that can perform many of the same measurement and characterization tasks that the spectrum analyzer (SA) can, but it can also perform many more useful digital demodulation functions. The VSA is… …
2Digital video testing — in broadcast video, for example, is the process of validating and verifying that the video content and other data is being correctly processed, stored and transported. Despite the fact that the data is digital, most digital tv (DTV) system… …
3Digital storage oscilloscope — A Tektronix TDS210 digital oscilloscope A digital storage oscilloscope is an oscilloscope which stores and analyses the signal digitally rather than using analogue techniques. It is now the most common type of oscilloscope in use because of the… …
4Digital pattern generator — A digital pattern generator is a piece of electronic test equipment or software used to generate digital electronics stimuli. Digital electronics stimuli are a specific kind of electrical waveform varying between two conventional voltages that… …
5Signal integrity — or SI is a measure of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. Over short distances and at low bit rates, a simple conductor can transmit this with… …
6Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… …
7Spectrum analyzer — A spectrum analyzer Spectrum analyzer display A spectrum analyzer measures the magnitude of an input signal versus frequency with …
8Network analyzer (electrical) — Not to be confused with packet analyzer or telecom network protocol analyzer. ZVA40 vector network analyser from Rohde Schwarz. A network analyzer is an instrument that measures the network parameters of electrical networks. Today, network… …
9Real Time Analyzer — A Real Time Analyzer (RTA) is a professional audio device that measures and displays the frequency spectrum of an audio signal; a spectrum analyzer that works in real time. An RTA can range from a small PDA sized device to a rackmounted hardware… …
10Audio signal processing — Audio signal processing, sometimes referred to as audio processing, is the intentional alteration of auditory signals, or sound. As audio signals may be electronically represented in either digital or analog format, signal processing may occur in …
