1.2 Setting the Vertical and Horizontal Axes
Time Axis ≡ Page 5-2. ≡
Setting the time axis
When using the internal clock, set the time axis scale as a time duration per division of the grid.
The setting range is 500 ns/div to 100 ks/div*. The time range in which waveform is displayed
is “time axis setting x 10”, as the display range along the horizontal axis is 10 divisions.
* 100 ks indicates 100000 seconds (27 hours 46 minutes 40 seconds).

1div=1 ms
Note
Display of time axis direction
The number of display points in the time axis direction on a 10-div screen is 1002 points (i.e. 2 points per
raster). Processing therefore varies according to record length, as described immediately below. (for more
details on the relation between time axis, record length and displayed record length, refer to Appendix 1).
• If record length exceeds number of screen display points (see page 8-2)
If the display style is set to “P-P”, the oscilloscope uses P-P compression to generate a 1002-point
display (regardless of interpolation setting).
If interpolation is “OFF” and the display style is set to “Decim,” the instrument thins the data to
generate a 1002-point display. If the display style is set to “All,” then all data points are displayed.
• If record length is less than number of screen display points
The instrument interpolates the data to generate the display. (See page 1-16.)

Relationship between the time axis setting, sample rate and record length
Changing the time axis causes corresponding changes in the sampling rate and the acquisition record
length. For more detailed information, refer to Appendix 1.
