SpecificationsOscilloscope Model DSO-4202C DSO-4102C DSO-4072C Sample Rate Sample Rate: 1GSa/s Equivalent Sample Rate: 25GSa/s Acquisition Modes Normal Normal data only Peak Detect High-frequency and random glitch capture Average Wavefom Average, selectable 4,8,16,32,64,128 Inputs Inputs Coupling AC, DC, GND Inpits Impendance 1MΩ±2% ‖20pF±3pF Probe Attenuation 1X, 10X Supported Probe Attenuation Factor 1X, 10X, 100X, 1000X Maximum Input Voltage CAT I and CAT II: 300VRMS (10×) CAT III: 150VRMS(1×); 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.
