To Select Modulation Source
The SDG6000X can accept a modulating signal from an internal or external
modulation source. Press Mod
→ FM → Source to select “Internal” or
“External” modulation source. The default is “Internal”.
1. Internal Source
The way of selecting the internal source is similar to AM.
2. External Source
When an external FM modulation source is selected, the generator accepts
the external modulating signal from the [Aux In/Out] connector at the rear
panel. At this time, the frequency of the modulated waveform is controlled by
the signal level applied to the connector. For example, if the frequency
deviation is set to 1 kHz, the output frequency will increase 1 kHz based on the
carrier frequency setting when the modulating signal is +6 V and decrease 1
kHz when the modulating signal is -6 V.
To Set Frequency Deviation
Press FM Dev to highlight the parameter, and then use the numeric keyboard
or arrow keys and knob to input the desired value.
The deviation should be equal-to or less-than the carrier frequency.
The sum of the deviation and the carrier frequency should be equal-to or
less
–than maximum frequency of the selected carrier waveform.
Note:
The way of setting other parameters of FM is similar to AM.
