; derate at 20 dB/decade above 900 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 instrument may result. Refer to the Overvoltage Category on the next page.

The float voltage must be subtracted from the tip-to-earth ground voltage. For example, if the reference lead is floated to
30 V
rms
, the tip voltage to the reference lead is limited to 270 V
rms
.
