2.3 Horizontal Setup
Horizontal settings, also known as timebase settings, adjust the display in horizontal
direction.
1. To set the timebase and horizontal position, use the TIME and POS keys.
2. To adjust all horizontal settings, select "Horizontal" in the main menu.
The determining point of an acquisition is the trigger point. Two parameters define the
position of the trigger point: reference point and horizontal position (also known as trig-
ger offset or delay). Using these parameters, you choose the part of the waveform you
want to see: around the trigger, before, or after the trigger.

Signal delay
If you have set a bandwidth limit, the signal might appear delayed on the screen. The
delay time depends on the selected filter. The effect is visible if several signals with dif-
ferent limits are displayed.
