1. Denotes warranted specifications, all others are typical. Specifications are valid after a 30-minute warm-up period and ± 5 °C from firmware calibration
temperature.
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.
6. External timebase reference values measured using a Wenzel 501-04608A 10 MHz reference. Intrinsic jitter value depends on acquisition time range for
Time Interval Error formula and depends on delta-time between edges for all two-edge formulas.
7. Skew between channels caused by ± 5 degrees C temperature change.
8. Initial = immediately after factory or user calibration.
