rms
Derate at 20 dB/decade above 100 kHz to 13 V peak AC at 3 MHz and above.
For nonsinusoidal waveforms, peak value must be less than 450 V. Excursion above 300 V
should be less than 100 ms duration.
RMS signal level, including any DC component removed through AC coupling, must be
limited to 300 V.
If these values are exceeded damage to the oscilloscope may result If these values are exceeded, damage to the oscilloscope may result.

Mode Rejection, typical
Sine wave with VOLTS/DIV setting at 5 mV. Signal applied between the channel (signal and
signal reference) and chassis. Ratio of the acquired signal amplitude to the amplitude of the
signal.
