Unless otherwise specified, all models of accuracy are ±1%, with an initial pulse response under high impedance load, such as 1 MΩ in parallel with 20 pF. A 50-ohm termination will reduce the output by half.
>Decline: For flat-topped current pulses, the output voltage decays to zero. Initially, the decay is linear, and the slope is called the decay rate.
Available rise time: If 10% to 90% rise time is greater than the specified available rise time, then the initial overshoot will be less than 10% of the pulse amplitude.
