BLMppR Series
Signal waveform (100nsec/div, 2V/div)
Ringing is caused on the signal waveform.
Such ringing contains several hundred MHz harmonic components and generates noise.
Signal waveform (100nsec/div, 2V/div)
Comparing initial waveform, ringing is suppressed a little.
However there still remains high level waveform distortion.
Signal waveform (100nsec/div, 2V/div)
BLM18R has excellent performance for noise suppression and waveform distortion suppression.
BLM18R suppresses drastically not only spectrum level in more than 100MHz range but waveform distortion.
