5.12.3 Carrier Frequency
Choose carrier waveform shape, press
Frequency/Period
to highlight "Frequency", and then use
the numeric keyboard or direction keys and knob to input the desired frequency.
T
he range is from 1μHz to 200MHz. The default frequency is 1KHz.
5.12.4 Modulating Waveform Source
Press
Mod
->
Source
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".
External Source
With the External source, the generator receives the external modulating signal from the
[Sync/Mod/Trig]
connector at the front panel.
5.12.5 OSK Rate
When internal modulation source is selected, press
Rate
softkey
to set the OSK frequency.
Use the numeric keyboard or direction keys and knob to input the desired frequency value.
The frequency range is from 2mHz to 1MHz and the default is 100Hz.
Note: This menu will be grayed out and disabled when the external modulation source are
selected.
5.12.6 Oscillate Period
Oscillate period is the oscillation period of internal crystal oscillator. The settable range of the
Sync/Mod/Trig
