modulation sensitivity.
External modulation sensitivity
The display shows the unit offset quantized by the amplitude of the externally modulated
signal, which is equal to the maximum offset when the external modulation input is full
scale. When the ―Int+Ext‖ modulation source is enabled, the internal and external each
account for 50% of the maximum offset, so when the external source inputs a full scale
signal, it only accounts for 50% of the maximum output offset.
Note: The modulation function must be activated to modulate the output signal. You can
turn it on or off by pressing the MOD ON/OFF button or you can open it by checking the
MOD module on the home page, as shown in the figure:
2.4.3 Phase Modulation (PM)

1. Click the MOD icon in the main interface to enter the MOD interface. The MOD

by clicking or sliding left.
