1.2 Keys and Knobs
Vertical Axis/Channel
CH1 to CH8 keys and LOGIC key
When you press any of these keys, a menu appears for turning analog signal input channels on
and off and for setting the coupling, probe type, offset voltage, bandwidth limit, linear scaling, and
waveform labels. Also, press any of these keys before pressing the SCALE or POSITION knob to
select which channel the SCALE knob will control. The LED between the SCALE and POSITION
knobs illuminates in the color assigned to the selected channel (the color around the CH key). Each
CH key illuminates when its corresponding channel is being displayed. The CH key being controlled
by the SCALE or POSITION knob illuminates. Use the LOGIC key to configure the logic channel.
POSITION Knob (Vertical position knob)
Use the POSITION knob to move the display position (vertical position) of the input waveform
along the vertical axis. Before turning this knob, press any of the CH1 to CH8 keys to specify the
waveform that you want to adjust the position of. This knob has a push switch. You can press the
knob to reset the trigger position to 0.00 div. You can also press the LOGIC key to produce the
same effect.
SCALE Knob
Use this knob to set the vertical scale. Before turning this knob, press any of the CH1 to CH8
keys to specify the waveform that you want to adjust the position of. If you change the scale while
signal acquisition is stopped, the waveform is expanded or reduced vertically. If you restart signal
acquisition, the instrument acquires signals using the new vertical scale. This knob has a push
switch. If you press the knob so that Fine illuminates, the resolution is set to fine mode.
When you press the LOGIC key, you can use this knob to change the vertical display size between
three levels.
CH UTIL Key
Use this key to display or hide all the waveforms of analog signal input channels and logic signal
input ports or to copy settings between analog signal input channels.
You can display all the waveforms of logic signal input ports by connecting a logic probe.
