NOTE:
The buttons on the front panel of the instrument are represented by words in a pane,
such as Sine which represents the functional key with “Sine” on it on the front panel,
while the menu buttons are represented by shadow words such as Freq, which means
the “Frequency” option in the Sine menu.

To Set a Waveform
At the left of the operation panel, there are several buttons with waveform icon and
two buttons which are used commonly. The following exercises will help you to be
familiar with the waveform selection settings. The instructions of the waveform
settings are all carried out in the Menu Display Mode.
Waveform Selection
Channel Switch Display Mode Switch
