1.2 Keys and Knobs
Vertical Axis and Channels
CH1 to CH4 Keys and LOGIC Key (On 4-channel models)
Displays a menu for turning analog signal input channels on and off, for expanding and
reducing the vertical axis, and for setting the vertical position, coupling, probe type, offset
voltage, bandwidth limit, linear scaling, and waveform labels. Also, press any of these
keys to select which channel the SCALE or POSITION knob will control. Channel keys
illuminate when the corresponding channel displays are on. And The LED between the
SCALE and POSITION knobs illuminates in the color assigned to the selected channel (the
color around the CH key).
Use the LOGIC key to configure the logic channel. At any given time, you can either use
the CH4 analog signal input channel or the logic channel. If you press LOGIC, the logic
channel is enabled. If you press CH4, the CH4 analog signal input channel is enabled.
The key that corresponds to the enabled channel illuminates.
POSITION Knob
Use this knob to change the center position when you change the voltage range. Before
you turn this knob, select the source waveform by pressing a key from CH1 to CH4 (or
LOGIC). This knob has a push switch. You can press the knob to reset the position to 0.0
divisions. You can also use this knob on the logic channel.
SCALE Knob
Use this knob to set the vertical scale. Before you turn this knob, select the target
waveform by pressing a key from CH1 to CH4 (or LOGIC). If you change the scale
while signal acquisition is stopped, the waveform is expanded or reduced vertically. The
setting actually takes effect when you restart signal acquisition.
This knob has a push switch. You can press the knob to switch the resolution. If you
press the knob so that Fine illuminates, the resolution is set to fine mode.
If the target signal is a logic signal, you can expand the waveform by three vertical levels.
Horizontal Axis
POSITION Knob
Use this knob to change the center position when you change the time-axis range. This
knob has a push switch. You can press the knob to reset the position back to 50%.
DELAY Key
When you press the DELAY key, the key illuminates. Then you can set the trigger delay
using the POSITION knob. You can reset the trigger delay to its default value (0 s) by
pressing the POSITION knob when the DELAY key is illuminated.
TIME/DIV Knob
Use this knob to set the time-axis scale. If you change the scale while signal acquisition
is stopped, the waveform is expanded or reduced horizontally. If you restart signal
acquisition, the DLM2000 acquires signals using the new time-axis scale.
Triggering
EDGE Key
Displays a menu for setting the edge trigger. When you press this key, the edge trigger is
selected, and the key illuminates.
ENHANCED Key
Displays a menu for setting the enhanced trigger. When you press this key, the enhanced
trigger is selected, and the key illuminates.
MODE Key and ACTION GO/NO-GO (SHIFT+MODE) Key
Displays a menu for selecting the trigger mode. Press SHIFT and then press MODE to
display an action-on-trigger menu.
