Test and Measurement

Waveform generation, visualization, and transmitter performance analysis

WLAN Toolbox™ provides functions that let you measure transmitter performance characteristics. The examples featured here demonstrate transmitter modeling and performance analysis. Communications Toolbox™ and DSP System Toolbox™ System objects provide additional quantitative tools for measuring system performance, and graphical utilities for visualizing waveforms.
