Speci fi cations
Table 3: Triggering system (cont.)
Characteristic Description
Frequency Range AC coupled, 10 Hz minimum to rated bandwidth.
Signal Source Pulse Width/ Edge Trigger: all available trigger sources.
Frequency Counter measures trigger source at all times, including when the oscilloscope
acquisition is halted due to changes in the run status, or acquisition of a single shot event
has completed.
Pulse Width Trigger: The oscilloscope counts pulses of signi fi cant 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 relatively small time.
Edge Trigger: The oscilloscope counts all edges of suf fi cient magnitude and correct polarity.
Video Trigger: The Frequency Counter does not operate.

Description
Real-Time Clock Battery
Real-Time Clock Battery The battery maintains time-of-day information when the oscilloscope is powered off.
The battery is sized to provide 5 years of service life.
The estimated time that the clock will remain powered from the battery is 5 years.
Environmental conditions, especially humidity, affect the number. The battery is not
user-replaceable.
