User Manual waveform will expand or contract to the screen center. The readout near the upper right of the screen shows the current horizontal position in second. The oscilloscope also has an arrow icon at the top of the graticule to indicate the horizontal position. 1. Horizontal Offset Knob: Used to control the trigger position against the screen center. Push this button to reset the trigger point back to the screen center. 2.SEC/DIV Knob: Used to change the horizontal time scale so as to magnify or compress the waveform horizontally. If the waveform acquisition is stopped (by using the [Run/Stop] or [Single] button), the SEC/DIV control will expand or compress the waveform. 2.6.
Vertical System 2.6.1. Vertical Controls Vertical controls can be used to display and remove waveform, adjust vertical scale and position, set input parameters and perform math calculations. Each channel has a separate vertical menu to set. See below for menu description. Vertical offset Volts/DIV knob 1. Vertical Offset Knob: Move the channel waveform up and down on the screen. In dual-window mode, move the waveform in both windows at the same time in a same direction. Push this knob to return waveform to the vertical center position on the screen. Two channels correspond to two knobs. 2. VOLTS/DIV Knob:
Control the oscilloscope to magnify or attenuate the source signal of the channel waveform. The vertical size of the display on the screen will change (increase or decrease) to the ground level. 3. Menu (CH1, CH2): Display vertical menu options; turn on or off the display of channel waveform. DC DC passes both DC and AC components of the input signal. Coupling GND AC AC blocks the DC component of the input signal and attenuates signals below 10Hz. Ground disconnects the input signal. BW 20MHz OFF Limits the bandwidth to reduce display noise; filters the signal to eliminate noise and other 16 / 67 Horizontal offset knob SEC/DIV knob Options Settings Comments
