2 Features and Functions
Frequency Sweep
In the frequency sweep mode, the U2761A “steps” from the
start frequency to the stop frequency at a sweep rate which
you specify. You can sweep up or down in frequency, and
with either linear or logarithmic spacing. You can also
configure the U2761A to output a single sweep (one pass
from start frequency to stop frequency) by applying an
External or Manual (software) trigger. The U2761A can
produce a frequency sweep for Sine, Square, Ramp, Triangle,
or Arbitrary’s waveform (Pulse and DC are not allowed). The
figure below shows an example of the frequency sweep.
