Since a total of eight input waveforms can be displayed, they may overlap each other, making
observation difficult. In this case, the waveforms can be moved in the vertical direction so that
can be observed more easily.
The vertical position can be set to any value in the range between
±
4 div.
Changing the V/div setting, the vertical axis setting is rescaled with respect to the vertical
position.
Position:2div
Position:-2div
Position:0div
Input coupling (For Voltage Modules)

When you only want to observe the amplitude of an alternating current signal, eliminating the
direct current components from the input signal makes observation easier. You may also want
to check the ground level or observe the input signal waveform with the offset voltage removed.
In these cases, you can change the input coupling setting. This will switch the coupling method,
which determines how the input signal is input to the vertical control circuit (voltage axis).
The input coupling method can be chosen from the following.
AC
The input signal is sent through a capacitor to the attenuator in
the vertical control circuit. This method can be used when you
just want to observe the amplitude of the alternating current
signal, eliminating the DC components from the input signal.
DC
The input signal is sent directly to the attenuator in the vertical
control circuit.
This method can be used when you want to observe both the DC
and AC components of the vertical input signal.
GND
The ground signal, not the input signal, is connected to the
attenuator in the vertical control circuit. This method enables
observation of the ground level on the screen.
Probe Attenuation (For Voltage Modules)

When making voltage measurements, using a probe to connect the circuit being measured and
the measurement input terminals has the following advantages:
• the voltage and current of the circuit to be measured are not disturbed;
• a signal can be input without distortion;
• the measurement voltage range of the oscilloscope can be widened.
When a probe is used, the probe attenuation must match the instrument’s attenuation setting so
that the input voltage can be measured directly.
Set to 10:1 or 1:1 when using the accessory voltage probe (700998).
Set to 10:1 when using the accessory isolating probe (700929).
In addition to 10:1, attenuations of 1:1, 100:1 and 1000:1 are provided.
When using a probe or cable besides the ones provided as accessories, set the appropriate
attenuation ratio meeting its specification.
