Frequency Sweep
In the frequency sweep mode, the waveform generator moves from the
start frequency to the stop frequency at a sweep rate which you specify.
You can sweep up or down in frequency, with either linear or logarithmic
spacing. You can also configure the waveform generator to output a
single sweep (one pass from start frequency to stop frequency) by
applying an external or manual trigger. The waveform generator can
produce a frequency sweep for sine, square, pulse, ramp, or arbitrary
waveforms (PRBS, noise and DC are not allowed).
You can specify a hold time, during which the sweep remains at the stop
frequency. You can also specify a return time, during which the
frequency changes linearly from the stop frequency to the start
frequency.
For more information on the fundamentals of a sweep, refer to chapter 5,
“Tutorial.”
To Select Sweep
• The waveform 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 and then press Sweep 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.
