A value measured under standard operating conditions as described in "General Specifications" after the warm-up time
has passed.
Trigger error, A input trigger error, B input trigger, rising trigger error, and falling trigger error are defined by the following
equation
X : Input amplifier noise

X +E n
En : Noise on the measured signal
S.R: Slew rate of the input signal (V/s)
