4.7 Setting and Operation of Modulation
WF1967/WF1968
4-56

Modulation type [ModType]
Select from FM, FSK, PM, PSK, AM, AM (DSB-SC), DC offset modulation, and PWM.

P.4-58
Off (modulation function not used) is also available as a selection in sweep oscillation mode
and burst oscillation mode. FSK and PSK cannot be selected in sweep oscillation mode and
burst oscillation mode except when using auto burst.

Synclator synchronization source [SyncSrc]
This only appears when the Synclator function is turned on. This oscillation frequency
synchronizes with the synchronization source specified here. The selection list is as follows:

P.4-32
Channel 1 Channel 2 (WF1968 only)
CH1 trigger input terminal
[Ext]
CH2 trigger input terminal [Ext]
- CH1 trigger input terminal [Ch1]
The polarity can also be selected.

Modulation width [Deviation, Depth, HopFreq]
The item name changes with the modulation type.

P.4-58
The modulation signal will have no effect on the main signal when the modulation width is set
to 0. Selecting internal for the modulation source and internal modulation waveform
[ModFctn] in the sub output selection [SubOut] will output an internal modulation signal from
the synchronization/sub output BNC terminal. At this time, the internal modulation signal
can be used as an independent signal source by setting the waveform, frequency, phase, and
amplitude/DC offset.

Modulation source [Source]
Select internal [Int] or external [Ext] for the modulation source.

P.4-58
Additionally, [Ch1] may be selected on channel 2 as same signal of channel 1. (WF1968 only)
[Ch1] can only be selected when the modulation mode is FSK or PSK and the channel 1
modulation source is set to [Int].
Internal cannot be selected in sweep oscillation mode.

Internal modulation frequency [ModFreq]
This is the frequency of the internal modulation source.

P.4-58
This item is not available when the modulation function is off or set to external modulation.

Internal modulation waveform [ModFctn]/Sub waveform [SubFctn]
Sets the waveform for the internal modulation source when the modulation function is turned
on and set to internal modulation. Select from the sine wave, square wave, triangle wave,
rising ramp wave, falling ramp wave, noise, and arbitrary wave.

P.4-58
Selects the sub waveform sent to the sub output when the modulation function is turned off or
not set to internal modulation.
