Operating the Oscilloscope
Following is a quick introduction to the oscilloscope. It is not intended as a
comprehensive guide, but rather as help for people who need only a brief overview.
Important features of the front panel
The front panel contains seven keypad areas and one set of softkeys. The figure on the facing
page shows the location of each of these areas, and the text below describes the functions of
the keys found in each area.
Some keys have two functions, one regular function and one shifted function. The shifted
function is the one printed in blue just above the key. To use a shifted function, first
press the blue key, indicated by (blue) in this book.
1 Entry/Measure area (Keypad)
The keys in this area have two functions. First, the numeric keys let you enter values in
menu areas that you have highlighted with softkey presses. These values might be for
voltages, vertical position, or other numerical data. The second function is the shifted
function of each key, measurements like Vp-p, Period, V avg, and Frequency written in
blue above the key. The (blue) key is also located in this area.
