Coupling
DC
AC
Ground
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.
20MHz Bandwidth Limit
Unlimited
Limited
Limits the bandwidth to reduce display noise; filters the signal to eliminate noise and other
unnecessary HF components.
VOLTS/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 Attenuation
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.
Invert
Off
On
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.
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.
4.
MATH MENU:
Display the waveform math operations. See the table below for details.
The MATH menu contains source options for all math operations.
