To Select the Carrier Waveform Shape
OSK carrier waveform can only be sine waveform. Press Sine at the front panel.
To Set the Carrier Frequency
After carrier waveform shape is selected, press Freq/Period to highlight "Freq"
and use the numeric keyboard or direction keys and knob to input the desired
frequency. The range is from 1μHz to 160MHz.
To Select the Modulating Waveform Source
Press Mod  Source to select "Int" or "Ext" modulation source.
1. Internal Source
When internal source is selected, the modulating waveform is set as a Square
with 50% duty cycle. At this point, the intermittence time and oscillate time of
the output signal is determined by the OSK "Rate".
2. External Source
When external source is selected, the generator receives external modulating
signal from the [Mod/FSK/Trig] connector at the rear panel.
