Basic Operation
QC1936 Digital Storage Oscilloscope 15
2.7 Vertical System
2.7.1 Vertical Controls
Vertical controls can be used to display and remove waveforms, 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.
1. VERTICAL POSITION Knob
Move the channel waveform up and down on the screen. In dual-window mode, move the
waveforms in both windows at the same time in a same direction. Push this knob to return
waveforms to the vertical center position on the screen. Two channels correspond to two knobs.
2. VOLT/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.
Also you may use this knob to switch between coarse and fine.
3. Menu (CH1, CH2): Display vertical menu options; turn on or off the display of channel
waveforms.
DC passes both DC and AC components of the input signal.
AC blocks the DC component of the input signal and
attenuates signals below 10Hz.
Ground disconnects the input signal.
Limits the bandwidth to reduce display noise; filters the
signal to eliminate noise and other unnecessary HF
components.
Selects the resolution of the VOLTS/DIV knob.
Coarse defines a 1-2-5 sequence. Fine changes the
resolution to small steps between the Coarse settings.
