When sweep is taking place, the frequency sweeps from start frequency to stop fre-
quency. Refer to Figure 2-2.
Figure 2-2: Frequency sweep
The instrument sweeps from a low frequency to a high frequency when start fre-
quency is set to be lower than stop frequency (start frequency < stop frequency).
The instrument sweeps from a high frequency to a low frequency when start fre-
quency is set to be higher than stop frequency.
The frequency range differs based on the selected waveform types. For frequency
sweep, you can select a sine, square, ramp, or arbitrary waveform. Pulse, DC, and
Noise waveforms cannot be selected.
You can select one of the following two operation modes:
Repeat. A continuous sweep is output at a rate specified by the sweep time, hold
time, and return time.
Trigger. One sweep waveform is output when a trigger input is received.
You can select a trigger source from an external signal applied to the front-panel
Trigger Input connector, the trigger signal generated internally, the manual trigger,
or the remote interface.
