Timebase Modes and Setup
Notes for using External Clock
Ø The time/div is expressed in s/div, to be understood to be samples/div.
Ø The trigger delay is also expressed in samples and can be adjusted as normal.
Ø No attempt is made to measure the time difference between the trig
clock. Therefore, successive acquisitions of the same signal can appear to jitter on the
screen.
Ø The oscilloscope will require a number of pulses (typically 50) before it recognizes the
external clock signal. The acquisition is halted only when the trigger conditions have
been satisfied and the appropriate number of data points have been accumulated.
Ø Any adjustment to the time/division knob automatically returns the oscilloscope to
normal (internal) clock operation.
