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 ºC temperature change.
8� Initial = immediately after factory or user calibration�
