Instructions

Digital Storage Oscilloscope 19
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. Also you can press this knob to
switch between coarse and fine.
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, CH3, CH4): Display vertical menu options; turn on or off the
display of channel waveforms.
Options Settings Comments
Coupling
DC
AC
GND
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.
BW 20MHz
OFF
ON
Limits the bandwidth to reduce display noise; filters
the signal to eliminate noise and other unnecessary
HF components.
Div
Coarse
Fine
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.
Probe
1X
10X
100X
1000X
Selects a value according to the probe attenuation
factor so as to ensure correct vertical readouts.
Reduce bandwidth to 6MHz when using a 1X probe.
