2.2 Setting the Horizontal and Vertical Axes
Pulse/Rotate Function <Section 5.14>
When the time base is set to external clock, one data sample is captured to the
acquisition memory when one pulse of the external clock signal is input. You can specify
the number of pulses of the external signal (in other words, the number of data samples
captured in the acquisition memory) that will correspond to one mechanical rotation (one
cycle). The selectable range is from 1 to 24000 pulses. For example, if the pulse/rotate
setting is set to 100 pulses, then 10 rotations of data samples will be acquired when the
record length is set to 1 kWord. When the pulse/rotate setting is set to 1 pulse, one data
sample will correspond to one rotation (one cycle).
The pulse/rotate setting affects only the X-axis (horizontal) measurement values in
cursor measurements and the time axis display on the screen. For example, if the pulse/
rotate setting is 100 pulses and the record length is 1 kWord, 1 division will be equal to 1
rotation. In this case, moving the cursor by 1 division during cursor measurements
causes the horizontal measured value to increase or decrease by “1.”
