Zoom Factor (MAG knob)
Use the Mag knob to set the zoom factor. You can set separate horizontal zoom factors for Zoom1 and Zoom2.
The zoom-window time-axis setting changes automatically based on the specified zoom factor.
Selectable Range
Two times the time axis setting (TIME/DIV) of the Main window to the point where the number of data points in
the zoom window reaches 10 points per div.
• When an external clock signal is being used as the time base, you can select one of the following
magnifications. You can select any magnification up to the point where the number of data points in the
zoom window reaches 10 points per div.
Up to 1000000 in 1-2.5-5 steps (×2, ×2.5, ×5, ×10, ×25, ×50, ×100, ×250, ×500, ×1000, ×2500, and so on)
• The upper limit of the zoom factor during hard disk recording is the maximum zoom factor that can be
displayed during hard disk recording.
Position (Zoom POSITION knob, Zoom1 Position, Zoom2
Position)
You can set the zoom position (position) using the zoom POSITION knob or the jog shuttle. Taking the horizontal
center of the main window to be 0 div, set the center position of the zoom boxes in the range of −5 to 5 div. In the
Main window, the box with solid lines is for Zoom1, and the box with dashed lines is for Zoom2. Waveforms are
magnified around the centers of the zoom boxes.
The Z1 or Z2 indicator on the front panel illuminates to show when the Zoom1 or Zoom2 window can be
moved by the Mag or zoom POSITION knob.
Zoom Link
If you press the Mag knob or zoom POSITION knob so that the Z1 and Z2 indicators both light, you can move
the zoom boxes while maintaining the spatial relationship between them. The relationship between the zoom
factors is also maintained.
