5.12.1 Select OSK Modulation
Press
[Mod] >Type > OSK
softkey to enable OSK function.
When
Mod
is enabled,
Sweep
or
Burst
will be disabled automatically.
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.
5.12.2 Carrier Waveform Shape
OSK carrier waveform can only be sine waveform. Press
[Wave]> Sine
softkeyon the front panel
to select.
5.12.3 Carrier WaveformFrequency
For different carrier waveforms, the settable range of carrier frequency is different. Please refer to
"Frequency Characteristics" in "
".The default value is 1kHz.
Press
[Setting] > Frequency
softkey on the front panel, and then use the numeric keypad or
direction keys and knob to input the desired frequency value.
5.12.4 Modulation Source
Press
[Mod] > Source
softkey to select Internal (default) or External as the modulation 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".
