Using the Oscilloscope 2Keysight Infiniium 9000 Series Oscilloscopes User’s Guide 35Adjusting the horizontal trigger position (delay)The horizontal position knob is the smaller of the two horizontal control knobs.Turn the knob to move the waveform to the right or left.Moving the waveform to the right shows more of the pre-trigger data (dataacquired before the trigger event). Moving the waveform to the left shows more ofthe post-trigger data.When you drag the desired waveform, the horizontal position will change for allchannels and functions on the display. Waveform memories will also move if youcheck the Tie to Timebase box in the Waveform Memories dialog box.You can also use the controls in the horizontal toolbar to adjust the horizontalposition. Mouse over or touch the horizontal position field and use the resultingcontrols to set a particular horizontal position (time relative to the trigger at thehighlighted horizontal reference point).Magnifying a part of the waveform using Zoom• To turn on zoom, press the key or click the Zoom button.The waveform display area splits into two regions. The top one is the maintimebase. The bottom is the zoomed timebase, which represents an expansionof the acquired waveform data. A section of the waveform in the main timebasewindow is highlighted to indicate the part shown in the zoomed timebasewindow.The horizontal scale and horizontal position controls now change how thewaveform is shown in the zoomed timebase window. The horizontal scale willchange the amount of magnification, while the position will change the part ofthe waveform in the main window that is shown in the zoomed window.• Press the key or click the Zoom button again to turn off Zoom.Setting the scale, position, and timebase referenceYou can use the Horizontal dialog box to set scale, position, and timebasereference. You can also set up the zoomed timebase window.To access the Horizontal dialog box, click the in the horizontal toolbar, orchoose Setup > Horizontal... from the menu bar.The Timebase Reference control is a slider from 0 to 100% of the screen. Thecenter of the screen is at 50%. The slider correlates to the solid orange triangle atthe bottom of the display area, showing you where the horizontal offset is on thescreen.
