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.

To Select Sweep
The U2761A does not allow the sweep mode to be enabled at the same time that any modulation mode is enabled.
