In the analog mode, magnification is limited to *10. The right key will activate the magnification. The left key will turn off the MAGNIFY function. On or off is indicated by ’MGN’ in the bottom of the screen.

Step 2 Press the ANALOG key to switch the scope to the digital mode.

Step 3 In the digital mode, pressing the right MAGNIFY key expands the signal in *1, *2, *4 ...steps to a maximum of *32 times. Pressing the left MAGNIFY key compresses the signal to *1 again. When you operate the MAGNIFY buttons, or when you turn the X POSition control, a bargraph is displayed showing which part of the digital trace is expanded.
