Improving Fidelity of Noise Repetitive Signals with Signal Averaging Technology

For many high-speed data acquisition applications requiring extraction of small repetitive signals from noisy environments, such as LIDAR or optical fiber testing, minimizing the effects of noise is a challenge for system design. Signal averaging provides dependable and efficient results. The article illustrates how FPGA-based signal averaging technology processes signals and reduces noise effects, improving signal-to-noise ratio (SNR) without occupying valuable CPU bandwidth.

Simplifying Power Added Efficiency Testing

Simplifying Power Added Efficiency Testing In most power added efficiency (PAE) test setups, multiple instruments are used to measure RF, voltage, and current. Measurements may require the use of an RF power meter or digital oscilloscope (DSO) with diode detectors to determine the RF power, while digital multimeters are used to measure voltage and current. The Agilent Technologies 8990B peak power analyzer (PPA) provides an alternative setup which allows power added efficiency testing to be done on a single instrument. Download now!
