1 Vertical Axis (Analog Signal)
You can configure the vertical scale, vertical position, input coupling, probe attenuation, linear scaling, and
bandwidth limit settings of the CH1 through CH4 input signals.
If you are using a probe that is compatible with this instrument’s probe interface, the instrument automatically
configures the input impedance (50 Ω or 1 MΩ) and the probe attenuation.
Turning the Display On and Off (Display)
Select whether show or hide each channel’s input signal waveform.
• ON: The waveform is shown.
• OFF: The waveform is hidden.
Vertical Scale (SCALE knob)
The vertical scale is used to adjust the displayed waveform amplitude so that you can easily view signals. Set
the vertical scale by voltage per grid square (V/div) or current per grid square (A/div) on the screen.
Set the vertical scale using the SCALE knob for each channel.
The SCALE knob is shared between channels. Press the CH1 to CH4 keys to select the channel that you want
to set the vertical scale for. The LED between the SCALE and POSITION knobs illuminates in the color assigned
to the selected channel (yellow, green, magenta, or cyan).
Setup Example
1 div = 1.00 V
1 div = 0.500 V
If 1.00 V/div is changed
to 0.500 V/div

• The SCALE knob has a push switch. If you push the SCALE knob, the FINE indicator illuminates, and you
can set the vertical scale with higher resolution.
Measurement Resolution and Effective Data Range
This instrument uses an 8-bit A/D converter to sample the input signal. The instrument’s effective data range
is 250 levels (LSB). The effective data range is ±5 divisions from the center of the screen, but only up to ±4
divisions of data can be displayed on the screen. If you move the vertical position after stopping waveform
acquisition, you can change the display range of the effective data.
Vertical Scale Setting
To measure the voltage or current with high accuracy, increase the vertical scale so that the input signal is
measured with the largest possible amplitude within the effective data range.
If you display multiple waveforms (set the vertical scale to a low value) so that they do not overlap without
dividing the screen, the resolution of the A/D converter cannot be used to its fullest potential. To make
accurate measurements, divide the screen, and set the vertical scale of each waveform to a high value.
Waveform Vertical Position (POSITION knob)
You can move the display position (vertical position) of each waveform in the range of ±4 divisions.
The vertical scale changes with the vertical position (mark) at the center.
Set the vertical position using the POSITION knob for each channel.
The POSITION knob is shared between channels. Press the CH1 to CH4 keys to select the channel that you
want to set the vertical position for. The key corresponding to the selected channel illuminates, and the LED
between the SCALE and POSITION knobs illuminates in the color assigned to the selected channel (yellow,
green, magenta, or cyan).
Position 2.00 div
Position –3.00 div
Position 0.00 div
Vertical position

After stopping signal acquisition, data falling outside the measurement range when you change the vertical
position is handled as overflow data.

Input Coupling (Coupling)
You can change the coupling used to input analog signals into the vertical (voltage) control circuit.
Select one of the following input coupling options.
AC
Displays only the AC component of the input signal. The input impedance is 1 MΩ.
DC
Displays both the AC and DC components of the input signal. The input impedance is 1 MΩ.
DC50
Displays both the AC and DC components of the input signal. The input impedance is 50 Ω. Pay attention
because the maximum input voltage (current) is small.

Probe Attenuation (Probe)
When using a probe, the instrument’s attenuation ratio setting must be aligned with the probe attenuation so
that the voltage (current) and scale values are displayed correctly. Set the attenuation ratio to match the probe
attenuation.
Probe Type (Type)
Select the type of probe to set the attenuation ratio of.
• Voltage: Voltage probe
• Current: Current probe
Attenuation Ratio (Attenuation)
Select the attenuation ratio from the following.
Voltage probe
0.001: 1, 0.002: 1, 0.005: 1, 0.01: 1, 0.02: 1, 0.05: 1, 0.1: 1, 0.2: 1, 0.5: 1, 1: 1, 2: 1, 5: 1, 10: 1, 20: 1, 50: 1, 100:

1 V, 2 A: 1 V, 5 A: 1 V, 10 A: 1 V, 20 A: 1 V, 50 A: 1 V, 100 A: 1 V, 200 A: 1 V, 500 A: 1 V, 1000 A: 1 V, 2000 A: 1 V
Using a probe has the following advantages.
• Prevents the disturbance of the voltage and current of the circuit being measured.
• Allows signals to be applied with no distortion.
• Expands the voltage range that the instrument can measure.

Automatic Zero Adjustment of Current Probes (Probe Zero CAL)
Automatic zero adjustment of current probes can be executed when all the following conditions are met.
• A current probe compatible with the instrument’s probe interface is connected to the signal input terminal.
• The input coupling is set to DC.
If the current probe’s residual offset is large, an error may occur when automatic zero adjustment is executed.
If this happens, adjust the current probe’s residual offset to zero.
Demagnetization and Automatic Zero Adjustment of Current Probes (DEMAG &
ZeroCAL)
Demagnetization and automatic zero adjustment of current probes can be executed when all the following
conditions are met.
• A current probe with a YOKOGAWA probe interface (e.g., PBC100, PBC050) is connected to the signal input
terminal.
• The input coupling is set to DC.
When you demagnetize and perform automatic zero adjustment on a current probe, do not clamp the
conductor. If you demagnetize a current probe while the conductor is clamped, the current that flows through
the conductor as a result of demagnetization may damage components of the DUT circuitry.
Deskew (Deskew)
You can adjust for the time offsets (skew) between the CH1 to CH4 signals, which are caused by the use of
different types of probes, and monitor the signals. You can adjust each channels (CH1 to CH4) separately.
Selectable range: −1000.0 ns to 1000.0 ns (0.01 ns resolution)
Inverted Waveform Display (Invert)
Waveforms can be inverted across the waveform vertical position. Only the display is inverted. Cursor
measurements, automated measurement of waveform parameters, and computation functions are performed on
the non-inverted waveform. The trigger function is also executed on the non-inverted waveform.
Linear Scaling (LinearScale)
The following computation is performed based on the specified scaling coefficient A and offset B, and cursor
measurement values and automated measurement values of waveform parameters are displayed using the
scaled values. You can assign units to scaled values.
By using this function, you can multiply the voltage divider ratio of the external voltage divider to the measured
values of this instrument and convert measured voltage into current.
Y(Unit)=AX + B
X: Value before scaling
Y: Value after scaling
Turning Linear Scaling On and Off (Mode)
Set whether to perform linear scaling.
• ON: Linear scaling is performed.
• OFF: Linear scaling is not performed.

Label (Name)
Set the label name when you set the label display to ON.
Bandwidth Limit (Bandwidth)
You can set a upper bandwidth limit on the analog signal for each channel.
This allows you to observe waveforms with components above the specified frequency removed.
Select the frequencies to limit from the following.
FULL (no bandwidth limit), 200 MHz, 100 MHz, 20 MHz, 10 MHz, 5 MHz, 2 MHz, 1 MHz, 500 kHz, 250 kHz, 125
kHz, 62.5 kHz, 32 kHz, 16 kHz, 8 kHz
When high resolution mode is on, the bandwidth limit is set at 200 MHz even when bandwidth limit is set to
FULL.
Offset (Offset)
If you set an offset when measuring an analog signal that is riding on top of a given voltage (or current), the
given voltage (or current) is subtracted from the input signal. This allows you to only view the changes in the
signal at a higher vertical scale setting.
You can set the offset for each channel.
Selectable Range for Voltage
Input Coupling Voltage Scale (With probe = 1:1) Selectable Offset Voltage Range
AC/DC 500 μV/div to 50 mV/div −1.0 V to 1.0 V
0.1 V/div to 0.5 V/div −10.0 V to 10.0 V
1 V/div to 10 V/div −100.0 V to 100.0 V
DC50 500 μV/div to 50 mV/div −1.0 V to 1.0 V
0.1 V/div to 1 V/div −5.0 V to 5.0 V
You can set the offset in 0.01 mV steps. For 500 μV/div, you can set the offset in 5 μV steps.

Offset Cancel (Offset Cancel)
You can set whether or not to apply the specified offset to various measured values.
The offset-cancel feature ON/OFF setting applies to all channels. The default setting is off.
• ON
The specified offset is applied to the result of cursor measurements, computations, and automated
measurement of waveform parameters. The offset is subtracted from the input signal, and various
measurements are performed. The vertical position is set to zero.
• OFF
The specified offset is not applied to the result of cursor measurements, computations, and automated
measurement of waveform parameters. The offset is not subtracted from the input signal, and various
measurements are performed. The vertical position on the screen corresponds to the offset.

• The offset setting applies to all input coupling settings (AC, DC, DC50).
• If you change the probe attenuation, the vertical scale settings change the values that have been scaled
with the new attenuation ratio.
• The offset value does not change even if you change the vertical scale. However, if the offset value goes
outside the selectable range, the offset is set to the maximum or minimum value in the vertical scale range.
If you do not change the offset and set the vertical scale back to its original value, the offset returns to its
original value.
