150 V. Derate at 20 dB/decade to 9 VRMS above 200 kHz.
The maximum input voltage at the BNC, between center conductor and ground is 400 V peak. The
RMS voltage is limited to <150 V for arbitrary waveshapes including DC. The maximum pulse width
for impulses with peaks over 150 V is 50 μs. Example: At 0 V to 400 V peak, rectangular wave, the
duty factor is 14%.
The maximum transient withstand voltage is ± 800 V peak.
5 V RMS, with peaks ≤ ± 24 V
