Oscilloscope Reference Acquisition mode
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 t
he trigger point.
The scale units depend on the waveform type. In most cases the horizontal units will be time. However,
the horizo
ntal units can als o be frequency.
TIP. Use the dedicated front-panel Horizontal Scale knob to change the horizontal scale.
