Installation Category II: derate at 20dB/decade above 100kHz to 13V
peak AC at 3MHz* and above. For non-sinusoidal waveforms, peak
value must be less than 450V. Excursion above 300V should be of less
than 100ms duration. RMS signal level including all DC components
removed through AC coupling must be limited to 300V. If these values
are exceeded, damage to the oscilloscope may occur.
