Frequency Sweep
In the frequency sweep mode, the function generator “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 function generator to
output a single sweep (one pass from start frequency to stop frequency)
by applying an external or manual trigger. The function generator can
produce a frequency sweep for sine, square, or ramp waveforms (pulse,
noise, dc, and arbitrary are not allowed).
For more information on the fundamentals of a sweep, refer to chapter 7,
“Tutorial”.
To Select Sweep
• The function generator will not allow the sweep mode to be enabled
at the same time that burst or any modulation mode is enabled.
When you enable sweep, the burst or modulation mode is turned off.
• Front-Panel Operation: You must enable sweep before setting up any
of the other sweep parameters. Press to output a sweep using
the present settings for frequency, output amplitude, and offset.
• Remote Interface Operation: To avoid multiple waveform changes,
enable the sweep mode after you have set up the other parameters.
