Frequency Sweep
The function generator can perform a sweep for sine, square or ramp
waveforms, but not noise, and pulse. When Sweep mode is enabled,
Burst or any other modulation modes will be disabled. When sweep
is enabled, burst mode is automatically disabled.
In Sweep mode the function generator will sweep from a start
frequency to a stop frequency over a number of designated steps. If
manual or external sources are used, the function generator can be
used to output a single sweep. The step spacing of the sweep can
linear or logarithmic. The function generator can also sweep up or
sweep down in frequency.
