FM Waveform
Supported PSG-A Series
Use this softkey to access a menu of choices that enables you to select the frequency
modulation waveform that can be produced by the internal modulation source.
Free Run
Supported All
This softkey is one of the choices in both the Sweep Trigger menu and the Point Trigger
menu. Choosing
Free Run in the Sweep Trigger menu immediately triggers the current
sweep when you press the
Single Sweep softkey. When sweep repeat is continuous and
Free Run is chosen for the sweep trigger, then sweeps are triggered consecutively (a new
sweep is triggered as soon as the current sweep ends). Choosing
Free Run in the Point
Trigger menu causes the sweep to pause for the dwell time at each point after the
hardware has been set up for that point’s frequency and amplitude.
