Generate waveforms and use quantitative tools to measure system performance. Use graphical utilities such as constellation and eye diagrams to visualize the effects of various impairments and corrections.
Wireless Waveform Generator | Create, impair, visualize, and export modulated waveforms |
BER Analyzer | Analyze bit error rate (BER) performance of communications systems |
Obtain numerical evaluation results.
Adjacent Channel Power Ratio (ACPR)
Adjacent channel power ratio (ACPR) calculations (also known as adjacent channel leakage ratio (ACLR)), characterize spectral regrowth in a communications system component, such as a modulator or an analog front end.
EVM Measurements.
Scatter Plots and Constellation Diagrams
Generating scatter plots.
Apply various RF impairments to a QAM signal.
This example shows how to plot a PSK constellation having 16 points.
In digital communications, an eye diagram provides a visual indication of how noise might impact system performance.
