2. Sample rate at maximum. Noise and slew rate determined at fixed-voltage measurement threshold, near middle of signal. Displayed signal not vertically
clipped. Slew rate of sine wave = (peak signal amplitude) • 2 • π • f, slew rate of fast step ~= (10 to 90% rise time).
3. Intra-channel = both edges on the same channel, inter-channel = two edges on different channels. Time Interval Error(Edge1) = time-interval error
measurement floor of first edge, Time Interval Error(Edge2) = time-interval error measurement floor of second edge.
4. Reading is the displayed Delta Time Measurement Accuracy measurement value. Do not double the listed Time Scale Accuracy value in Delta Time
Measurement Accuracy formula.
5. Scope channels and signal interconnect de-skewed prior to measurement.
