Behavior. The horizontal delay feature is useful when you want to acquire waveform details that are separated from the trigger
event by a significant interval of time.
For example, you can trigger the instrument on a sync pulse that occurs once every 10 ms, and then look at the high-speed
characteristics that occur 6 ms after the pulse.
TIP. A convenient way to use the horizontal delay is to make quick comparisons between two different points in time. Trigger the
instrument on one area of interest and then set the horizontal delay to acquire the other area of interest. You can then toggle the
horizontal delay on and off to compare details at the two points in time.

Overview.
To use.

Click in the Scale entry box and use the multipurpose knob or keypad to change the setting.
Behavior. Use the Scale control to adjust the time base. This control scales all live displayed waveforms at the same time. When
horizontal delay is on, the scale expands or contracts around the horizontal reference point instead of the trigger point.
The scale units depend on the waveform type. In most cases the horizontal units will be time. However, the horizontal units can
also be frequency.
TIP. Use the dedicated front-panel Horizontal Scale knob to change the horizontal scale.
