Repeat this procedure for the remaining channels on your oscilloscope.
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 5080A
and the signal’s peaks are matched to the graticule line divisions on the oscilloscope.
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.

Each option in the Marker menu is described below.
•
OUTPUT @ SCOPE
terminal Indicates the location of the signal output. If the
signal does not appear on the oscilloscope, press
. To disconnect the signal, press
.
•
SHAPE
Indicates the type of waveform. Depending on frequency setting, possible
selections are sine, spike, square (50 % duty cycle square wave), and sq20% (20 %
duty cycle square wave.) Note that selections available under SHAPE depend on the
selected marker period (frequency), shown in Table 1.
