7.7 Sweep Oscillation Mode
7.7.1 General
Sweep types Frequency, phase, amplitude, DC offset, duty
Sweep functions One-way (ramp waveform shape), shuttle (triangular
waveform shape) (selectable)
Linear, log (frequency sweep only) (selectable)
Sweep range setting Start value and stop value specification
Center value and span value specification.
