⚫
After OSK is enabled, the instrument will generate OSK waveform with the
currently specified carrier and modulating waveforms. To avoid multiple waveform
changes, enable modulation after configuring the other modulation parameters.

Carrier Waveform Shape

OSK carrier waveform can only be sine waveform. Press [Wave] >

Carrier Waveform Frequency

For different carrier waveforms, the settable range of carrier frequency is different.
Please refer to "Frequency Characteristics" in Specifications. The default value is 1kHz.

source.
internal Source
When internal modulation source is selected, the modulating waveform is set as a
Square with 50% duty cycle, and the intermittence time and oscillate time of the output
signal is determined by the OSK "Rate".
external Source
When external modulation source is selected, the signal generator receives the external
modulation signal from the [FSK/Trig/Sync/Extmod] connector on the rear panel.
