4.6 Setting the Modulation
4.6.1 Outline of Modulation
This signal generator provides AM and FM modulation functions. The FM modulation has two systems: FM1 and
FM2, frequency deviation of which can be set independently of each other.
This unit also comes with 5 different modulation signal sources, as shown below, and you can select any one of
them for each type of modulation.
Internal modulation : Int1 ........ Sine wave of 1 kHz or 400 Hz
Int2 ........ 0.01 Hz to 400 kHz digital synthesizer
Int3 ........ 0.01 Hz to 400 kHz digital synthesizer
External modulation : Ext1 ....... Signal supplied to the Mod Input Ext1 connector
Ext2 ....... Signal supplied to the Mod Input Ext2 connector
The flow of modulation signals is graphically presented below:
