1.2 Keys and Knobs
Vertical Axis/Channel
CH1 to CH4 Keys and LOGIC Key (4 channel model)
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. You can use either CH4 or logic. When you press
LOGIC, CH4 changes to logic. When you press CH4, logic changes to CH4. The active key, CH4 of
LOGIC, illuminates.
POSITION Knob
Use this knob to change the center position when you change the voltage range. Before turning this
knob, press any of the CH1 to CH4 (LOGIC) 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 position to 0.0 div. You
can also use this knob on the logic channel.
SCALE Knob
Use this knob to set the vertical scale. Before turning this knob, press any of the CH1 to CH4 (LOGIC)
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.
If the knob is controlling LOGIC, you can expand the waveform vertically in three steps.
