The APPLy command always enables autoranging.
Output Control
By default, channel output is disabled at power on to protect other equipment. To enable a channel's output, see below.
When channel output is enabled, the corresponding channel button is lit.
If an external circuit applies excessive voltage to a channel output connector, the instrument generates an error
l
message and disables the output. To re-enable output, remove the overload and turn the channel on again.

The APPLy command always enables the channel output connector.
Waveform Polarity
In normal mode (default), the waveform goes positive at the beginning of the cycle. Inverted mode does the opposite.
As shown below, the waveform is inverted relative to the offset voltage. The offset voltage remains unchanged
l
when the waveform is inverted.
The Sync signal associated with an inverted waveform is not inverted.
