Users can configure HDG2000B to output basic waveform from a single channel or from dual
channels at the same time. Please select the desired channel before configuring waveform
parameters. At start-up, CH1 is selected by default. Press CH1/CH2 button at the front panel and
the corresponding area in the user interface is illuminated. At this point, users can configure the
waveform and parameters of the channel selected.
Note: CH1 and CH2 cannot be selected at the same time. Users can first select CH1 and then
