Power amplifier co-channel non linear distortion meter includes a pseudo random sequences generator and automatic integration of the instrument calibration

摘要

The power amplifier co-channel non-linear distortion metal has a pseudo-random sequences generator with attenuators, phase changers and amplifier assemblies. The ratios between the signal level and the distortion in the adjacent channel and the components not correlated with distortion in the channel can be calculated. EMBODIMENT - The instrument calibration is automatically integrated in the measurement process.
