DSO Menu Figure 6: DSO menu bar File Menu Save: after clicking on this icon, a save window appears, enabling you to save configurations, data and measurements files for each acquisition. In the case of being connected to multiple DSOs, there are check boxes next to each DSO, check the one related to the needed DSO and save preferences. - Page 15 The version for this software can be found after selecting the “About” under “help” menu option. Zooming can be done by clicking on the graph and dragging, which would draw a dotted window. When the mouse is released, the graph will zoom to display only the content within the drawn box.
