6. Remove the input signal by pressing Y.
7. Repeat this procedure for the remaining channels on your oscilloscope.

8-39. Calibrating the Time Base of an Oscilloscope

The horizontal deflection (time base) of an oscilloscope is calibrated using a method
similar to the vertical gain calibration. A time marker signal is generated from the
Calibrator and the signal's peaks are matched to the graticule line divisions on the
oscilloscope.

8-40. The Time Marker Function

The Time MARKER function, which is available through the MARKER menu, lets you
calibrate the timing response of your oscilloscope. To access the MARKER menu, press
the softkey under MODE until "marker" appears.
You can press the MODE softkey to cycle through the functions in the order shown, or
you can press P to return directly to the SCOPE menu.
Each option in the MARKER menu is described below:
