4.4 Setting for Main Items
WF1967/WF1968
4-50
Outputs the main signal's waveform reference phase synchronization signal (50% duty square
wave which rises at the main signal's 0° point).

Sub Waveform [SubFctn]
Outputs the sub waveforms common to the only frequency of main signal.

Output Disabled [Off]
Output is fixed at a low level. This helps to reduce interference from the synchronization
signal.
4.4.20 To Use Sub Waveforms
If you use the sub waveform, it is available as a two-phase oscillator in WF1967, or a maximum four
phase oscillator in WF1968.
a) When Sub Waveforms is available
Sub waveforms can be used when following Condition 1. Sub waveforms are output from the
synchronization/sub output BNC terminal. It also shows the settings to use the modulation
waveform as a sub-waveform in condition 2. This setting is characterized by can be set to a
frequency different from the main waveform. However, only when this is not necessary to output
a modulated wave to the main waveform for use.

b) To Set Sub Waveforms
Select the sub waveform [SubFctn] on the second page or modulation function [ModFctn] on the
third page of the Oscillator setting screen.
Select from the following seven options:
• Sine wave [Sine] • Down ramp wave[DnRamp]
• Square wave (duty 50%) [Square] • Noise[Noise]
• Triangle wave (symmetry 50%) [Triangle] • Arbitrary wave[ARB]
