81100 Family of Pulse/Pattern Generators
技术概述
Keysight Technologies, Inc. pulse/pattern generators are used for research in the aerospace and defense industry, among others.
One example of their use is in the reduction of takeoff and landing times at airports and the prevention of problems caused by wake vortex. Here, the industry works with methods like PIV (Particle Image Velocimetry) where a laser sends a double light pulse out. Particles in a flow get illuminated by the pulses and a camera takes pictures every time the particle reflects the light. (Figure 1)
The 81150A can simulate this double light pulse by varying the delay and the repetition frequency of the pulses.
