Digital Storage Oscilloscope 13
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. 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. Also you may use this knob to switch between coarse
and fine.
3. Menu (CH1, CH2, Ch3, CH4): 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.
