• Overload protection: 600 V
• Input amplitude a: (DC level = 0)
≤100 kHz: 200 mVrms ≤ a ≤ 20 Vrms
>100 kHz - 1 MHz: 600 mVrms ≤ a ≤ 30 Vrms
• Duty ratio measurement is applicable to zero-crossing square waves with frequency
≤10kHz.
1 Vpp ≤ Input amplitude ≤ 30 Vpp.
Frequency ≤ 1 kHz, duty ratio: 10.0 % to 90.0 %.
