1. Everything to the right of the trigger point is called post trigger information The amount of delay range pre trigger and post trigger information available depends on the time div selected and memory depth The horizontal position knob works in the Normal time mode while acquisitions are running or when they are stopped When running adjusting the horizontal scale knob changes the sample rate When stopped adjusting the horizontal scale knob lets you zoom into acquired data See Panning and Zooming Single or Stopped Acquisitions on page 46 Keysight InfiniiVision 2000 X Series Oscilloscopes User s Guide 45 2 Horizontal Controls Note that the horizontal position knob has a different purpose in the Zoom display See To display the zoomed time base on page 50 Panning and Zooming Single or Stopped Acquisitions When the oscilloscope is stopped use the horizontal scale and position knobs to pan and zoom your waveform The stopped display may contain several acquisitions worth of information but only the last acquisition is available for pan and zoom The ability to pan move horizontally and scale expand or compress horizontally an acquired waveform is important because of the additional insight it can reveal about the captured waveform This additional insight is often gained from seeing the waveform at different levels of abstraction You may want to view both the big picture and the specific little picture de
