INPUT 1 in COMMON mode:
Sensitivity
×1 attenuation
Sinewave:
10Hz ≤ f ≤ 100MHz
100MHz < f ≤ 160MHz
160MHz < f ≤ 200MHz
where: f is the input frequency in Hz
Pulse:
75mV for pulse widths down to 5ns
Variable Sensitivity (Hysteresis)
Two selectable settings of the hysteresis level allow the sensitivity to be adjusted. The
above Sensitivity figures are with the hysteresis in its most sensitive position, but the
sensitivity will be reduced by a factor of 2 nominal upon selecting the other setting.
Dynamic Range
x1 attenuation:
10Hz ≤ f ≤ 50MHz
50MHz < f ≤ 160MHz
