Electrical Engineering Laboratory Equipment Manual
displayed here. If the scope is stopped, a solid octagon (stop sign) along with ―Stop‖ will be
displayed. The next bit of information that you find along the top of the display is the middle
graticule time readout. It displays the time to which the middle graticule corresponds. The t = 0
position is indicated by the upside down solid arrow at the top of the display.
At the bottom left corner of the display is a readout of the status of the input channels. It
indicates what channel(s) are on, and what their volts/div settings are. To the right of this
information you will find the main time/div setting, preceded by an M. Finally, in the bottom
right corner is information regarding the trigger source, trigger slope, and trigger level.
At the left side of the display you will see the channel number (1 or 2) and an arrow
pointing to the right. This indicates the ground (0 V) position for that channel. At the right side
of the display you will see another arrow pointing to the left. This arrow graphically indicates
the current trigger level.
Channel Menus and Vertical Controls
Pressing either channel menu (1 or 2) brings up a list of items adjacent to the five
softkeys at the right of the display. These menu items are as follows:
 Coupling dc/ac/ground
 Bandwidth limit off (60 MHz) / on (20 MHz)
 Volts/div coarse/fine
 Probe 1X/10X/100X/1000X
 Invert off/on
The volts/div for each channel are adjusted by using the large VOLTS/DIV adjust knobs.
The vertical position of the waveforms on the screen are adjusted with the small position knobs.
To turn a channel on/off, simply repeatedly press its channel menu button.
Timebase / Horizontal Controls
The horizontal position knob adjusts the
horizontal position of the display left or right by
moving the t = 0 point. The upside down arrow at
the top of the display indicates the t = 0 position and
will move left or right as the horizontal position
knob is turned. The large SEC/DIV knob adjusts
the timebase of the scope.
