Sweep
DG2000 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. DG2000 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
When the Shift key is illuminated, press Home/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
DG2000 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".
When the Shift key is illuminated, press Home/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.
