Basic Operation
DSO5000P Series Digital Storage Oscilloscope User Manual 20
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.
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.
Inverts the waveform relative to the reference level.
Ground Coupling
Used to display a zero-volt waveform. Internally, the channel input is connected with a zero-volt
reference level.
Fine Resolution
In the fine resolution setting, the vertical scale readout displays the actual VOLTS/DIV setting. The
vertical scale changes only after you adjust the VOLTS/DIV control and set to coarse.
Remove Waveform Display
To remove a waveform from the screen, first push the menu button to display the vertical menu,
then push again to remove the waveform. A channel waveform which is unnecessary to be
displayed can be used as a trigger source or for math operations.
3. 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.
4. MATH MENU: Display the waveform math operations. See the table below for details.
The MATH menu contains source options for all math operations.
Add Channel 1 to Channel 2.
Subtract the Channel 2 waveform from the Channel 1
waveform.
Subtract the Channel 1 waveform from the Channel 2
waveform.
Channel 1 multiply channel 2
Channel 1 divide channel 2
Channel 2 divide channel 1
