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.
