Configuring a Swept Output
The signal generator has two methods of sweeping through a set of frequency and amplitude points:
Step sweep (page 28) provides a linear or logarithmic progression from one selected frequency, or
amplitude, or both to another, pausing at linearly or logarithmically spaced points (steps) along the
sweep. The sweep can progress forward, backward, or manually.
List sweep (page 29) enables you to enter frequencies and amplitudes at unequal intervals, in
nonlinear ascending, descending, or random order. List sweep also enables you to copy the current
step sweep values, include an Arb waveform in a sweep (on a vector instrument), and save list sweep
data in the file catalog (page 37).

Sweep without waiting for
a trigger at each point.
Point Trigger pauses for the dwell
time prior to the first sweep.
Apply a TTL/CMOS signal to the
Trigger In connector.
Periodically issue a trigger event to
whatever selects it as a source.
Using timer trigger with single
sweep results in a delay prior to the
first sweep.
Trigger on a remote command.
Down sweeps from
stop to start
frequency/amplitude
Up sweeps from sta
to stop
frequency/amplitude

The selected sweep type determines the displayed parameter.

During a frequency sweep, the CW frequency does not display; for an amplitude sweep, the amplitude does not display;
for a frequency and amplitude sweep, neither frequency nor amplitude displays.
Progress Bar: very fast sweeps can
appear to sweep randomly or backward
