Modulation source [Source]

Either an internal or external modulation source can be selected.



p.76

Internal modulation waveform [ModFctn]

This is the internal modulation source waveform. Sine, square, triangular, rising ramp, falling

ramp, noise, and arbitrary can be chosen from.



p.76

Internal modulation frequency [ModFreq]

This is the frequency of the internal modulation source.



p.76

Sync output [SyncOut]

This is the output signal from the sync/sub-output terminal. Waveform basic phase sync, internal

modulation sync, and internal modulation waveform can be chosen from.
