Channel on/off CH1 to CH8
1
and Logic can be turned on and off independently.
At the maximum record length, all even-numbered channels and Logic (C, D)
2
are automatically
turned off.
Logic waveform bus display Bus display is possible on the selected bits (A0 to A7, B0 to B7, C0 to C7 2 , D0 to D7 2 ) of the logic
waveform.
Logic waveform state
display
Displays logic signals that have been sampled on the edges of a clock source. Even when the input
signal changes, a state is retained until the clock source edge changes.
For the clock source, select from the logic waveform bits (A0 to A7, B0 to B7, C0 to C7
2
, D0 to D7
2
).
Vertical position Turning the vertical position knob moves the vertical position of a waveform in the range of ±4 div.
Analog waveform: A waveform can be moved in the range of ±4 div from the center of the waveform
display frame. CH1 to CH8
1
are moved separately.
Logic waveform: The logic waveforms can be moved in the range of ±4 div from the center of the
waveform display frame.
Press the vertical position knob to reset the position to its default value.
Vertical scale The vertical scale knob can be used to set the vertical scale.
Press the SCALE knob to switch between a mode in which you can set values in 1-2-5 steps or a
mode in which you can set values in detail (FINE).
For the selectable range when using 1-2-5 steps, see “Analog Signal Input” in Section 6.1, “Signal
Input Section.”
FINE vertical scale is achieved through digital zooming.
If you change the scale while the instrument is stopped, you can vertically expand or reduce
waveforms.
Logic waveforms can be expanded to three different display-size levels.
Input filter Bandwidth limit can be set independently for CH1 to CH8. 1
For the available filter types, see "Bandwidth limit" in section 6.1, "Signal Input Section.”
Offset canceling Offset canceling can be turned on and off collectively for CH1 to CH8.
1
OFF: Does not apply the specified offset to the result of cursor measurements, computations, and
automated measurement of waveform parameters.
ON: Applies the specified offset to the result of cursor measurements, computations, and automated
measurement of waveform parameters.
Inverted display Waveforms can be inverted around the vertical position for CH1 to CH8
1
separately.
Configuration and measurement values are executed on the waveforms before the inversion.
Linear scaling The scaling factor, offset value, and unit can be set independently for CH1 to CH8.
1
Logic signal threshold level
preset
You can choose from the following preset threshold level settings.
CMOS (5 V) = 2.50 V, CMOS (3.3 V) = 1.65 V, CMOS (2.5 V) = 1.25 V, CMOS (1.8 V) = 0.90 V, and
ECL = –1.30 V
Deskewing Deskewing is possible on CH1 to CH8
1
and Logic input signals.
For logic waveforms, adjustment is possible at the port (pod (8 bit)) level, but not at the bit level.
The adjustable range is ±1 μs in 0.01 ns steps.
Triggers are activated on the deskewed signals, but the deskewing on the trigger side is in 400 ps
steps.
Horizontal position Horizontal position knob can be used to set the trigger position and trigger delay.
The knob is set to the following functions depending on the DELAY key LED state.
LED off: Trigger position
LED on: Trigger delay
For trigger position and trigger delay specification details, see “Trigger position” or “Selectable
trigger delay range” in section 6.2, “Triggering Section.”
Delay canceling You can select whether to apply the specified delay to the time measurement values.
ON: Measures time with the trigger position set to 0 s (does not apply the delay to time
measurement).
OFF: Measures time with the trigger point set to 0 s (applies the delay to time measurement).
Time scale setting The time scale can be set using the TIME/DIV knob.
For the selectable range, see “Selectable time scale range” in section 6.3, “Time Axis.”
If you change the time scale while the instrument is stopped, you can expand or reduce waveforms
along the time axis.

2 Logic C0 to C7 and D0 to D7 are part of the /L32 option.
