exercise will help you get familiar with vertical setups.
Fig. 1‐4 Vertical Control Area Shown on the Front Panel
Turn the "VERTICAL POSITION" knob to move waveform in vertical direction and channel displaying position
returns to median once this knob is pressed down.
CH1, CH2, REF, MATH keys are for the display of operational menus for vertical channel, opening or closing a
waveform being displayed through the channel.
"SCALE" is used to set vertical scale coefficient
1. Press "POSITION" knob (for vertical shift) to make the waveform display signal at the central position of the
window. Turn the "POSITION" knob (for vertical shift) to control the vertical displaying position of the signal. The
reference marker of the ground level of the channel moves up and down with the waveform.
2. Change the setup of vertical system and observe the change of status information. You can know the vertical
range change from the information shown in the status bar located at the lower part of the waveform window.
Turn the vertical "SCALE" knob to change the coefficient of vertical scale ‐ "VOLTS/DIV" and you may notice from
the status bar the corresponding change of vertical scale coefficient shown for each channel. If press CH1, CH2,
REF, MATH key one after another, the screen will display the operational menus, logos, waveforms and range
status information for the corresponding channel.
Measurement Skills:
If channel coupling method is DC, you can measure the signal's DC component swiftly by
observing the distance between waveform and electrical level of the signal earth.
If the coupling method is AC, DC component contained in the signal will then be filtered,
which make it easier for you to display the AC component using higher sensitivity.
1.9 Preliminary Understanding of Horizontal System
As shown below, there are two keys and two knobs located within the horizontal control area. The following
exercise will help you get familiar with horizontal time base setups.
