Sweep
DG800 can output sweep waveforms from a single channel or from dual channels at
the same time. In sweep mode, the generator outputs a signal variably from the start
frequency to stop frequency within the specified sweep time. DG800 supports linear,
log, and step sweep modes; allows users to set start hold, stop hold, and return time;
supports internal, external, or manual trigger source; and capable of generating
sweep output for Sine, Square, Ramp, and Arbitrary waveform.
To Enable the Sweep Function
Press Menu

Sweep to select "Linear", "Log", or "Step" to enable the sweep
function. The Modulation or Burst function will be disabled automatically (if
enabled currently). At this time, the generator will generate the sweep waveform
from the corresponding channel (if enabled currently) according to the current
configuration. You can also reset the sweep parameters. For details, refer to the
following section.
Sweep Type
DG800 provides Linear, Log, and Step sweep types.
Linear Sweep
In the linear sweep type, the output frequency of the instrument varies linearly in the
way of "several Hertz per second". The variation is controlled by "Start Frequency",
"Stop Frequency" and "Sweep Time".
Press Menu

Sweep

"Linear" to enable the linear sweep. A straight line is
displayed on the waveform on the screen, indicating that the output frequency varies
linearly.
