Under RATE, replace the first paragraph with the following:
• RATE Used when FREQ CHANGE is set to “sweep” to select a the sweep speed of 100 kHz, 1 MHz or
10 MHz.
On page 8-77, replace step 2 with the following:
2. Toggle FREQ CHANGE to “sweep.” Toggle the RATE to a lower frequency if you want to observe a
very slow sweep over a small range.
Replace page’s 8-80 and 8-81, with the following:
8-106. 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.
8-107 . 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:
• OUTPUT @ SCOPE terminal (50Ω) Indicates the location of the signal output. If the signal does
not appear on the oscilloscope, press O. To disconnect the signal, press Y.
