1. Press one of the CH1 to CH8/4 and LOGIC keys to select the channel. The CH
menu or LOGIC menu appears.
You can select up to channel CH4 and CH8 on the DL7440 and DL7480, respectively.
2. Press the Display (when CH1 to CH8/4 is selected) or Mode (when Logic is
selected) soft key to select ON or OFF. You can also turn ON/OFF the channel
by pressing CH1 to CH8/4 or Logic twice.
For channels that are turned ON, the LED to the left of the channel key illuminates.
The input waveform of 8 or 4 channels (CH1 to CH8/4) and the optional logic input
waveform can be displayed simultaneously. If the logic input is turned ON, a logic
waveform window opens as shown below. You can also display on the logic waveform
(see section 8.1).
Note
• The screen can be split into up to eight display areas using the DISPLAY menu (see section
8.1). Scale values (see section 8.8) and waveform labels (see section 8.9) can also be
displayed.
• If waveforms are recalled from the history waveforms or loaded from a storage medium such
as a floppy disk or Zip disk, the input waveform cannot be displayed. To compare input
waveforms and loaded waveforms, use the snapshot function (see section 8.6).
• To exit the menu during operation, press ESC located
above the soft keys.
• For a description of the operation using a USB keyboard or
a USB mouse, see section 4.3.
