within the specified operating temperature range. See page 1--8.

H You must perform the Do Self Cal operation, accessible through the Utility

menu, if the operating temperature changes by more than 5 °C.

H The oscilloscope must be within the factory calibration interval of one year.

Pulse Width Trigger: The oscilloscope counts pul ses of significant magnitude inside the 250 ms measurement window that qualify as triggerable events, such as narrow pulses in a PWM pulse train if set to < mode and the width is set to a relat ively small time.

Edge Trigger: The oscilloscope counts all edges of sufficient magnitude and correct polarity.
