When the modulation source selects
“Int+Ext”, the set value is the maximum value of
the total offset, the internal source accounts for 50%, and the external source accounts for
50%.
RF output offset = set value × 0.5 + external input signal amplitude × external
modulation sensitivity
.
PM Sensitivity
Display the PM deviation unit offset which quantized by the amplitude of external signal.
When the external signal is full scale, actual offset will be max. Specially, when the PM
source is “Int+Ext”, the offsets caused by internal and external sources are evenly split.
When the external signal is full scale, the offset caused by it will be half of the total 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:
