Channel on/off
CH1 to CH4
1
and LOGIC can be turned on and off independently.
Either CH4
1
or LOGIC
2
can be turned on at any given time.
At the maximum record length, all even-numbered channels, including LOGIC,
2
are automatically
are turned off.
Logic waveform bus display Bus display is possible on the selected bits (bit 0 to 7) 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 LOGIC(L) port, you can select the clock source from CH1 to CH3 or from logic bits 0 to 7.
If state display is turned on, Math4 cannot be used.
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 CH4
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 sensitivity 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 CH4.
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 CH4.
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 CH4
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 CH4.
1
Logic signal threshold level
preset
You can choose from the following preset threshold level settings.
COMS (5V)=2.50V, CMOS (3.3V)=1.65V, CMOS (2.5V)=1.25V, CMOS (1.8V)=0.90V, ECL= -1.30V
Deskewing
Deskewing is possible on CH1 to CH4
1
and LOGIC
2
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 ±100 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 cancelling
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.
