s/Div Field

s/Div Field
The s/Div field allows you to set the sweep speed (time scale) on the
horizontal axis of the display. Sweep speed is measured in seconds per
division.
Selecting Sweep Speed
The waveform display is divided into 10 horizontal divisions. The divisions
are marked by small tan-colored tick marks at the top and bottom of the
waveform display area.
If you have a multi-card oscilloscope configuration, the s/Div field is set on
the master card. All other cards in the multi-card module will use the same
s/Div setting as the master card.
When you select the s/Div field, you can change the sweep speed for the next
acquisition by turning the knob. Turning the knob clockwise a small amount
expands the displayed waveform horizontally in both directions from the
center of the display. Turning the knob counter-clockwise a small amount
compresses the displayed waveform horizontally in both directions toward
the center of the display. As you turn the knob, the sweep speed changes in
a 1-2-5 sequence (10.0 ns, 20.0 ns, 50.0 ns, etc.) from 1 ns/div to 5 s/div
(HP 16533A) and 500 ps/div to 5 s/div (HP 16534A).
Sweep speed can also be entered from the pop-up keypad. The keypad
appears when you touch the light-blue s/Div field. Any value from 500 ps/div
to 5 s/div (HP 16534) and 1ns to 5s/div (HP 16533) can be entered from the
keypad. Sweep speed values are rounded and then truncated to the three
most significant digits. For example, if you enter a value of 15.45 ns, the
value is rounded and then truncated to 15.5 ns.
