RIGOL Chapter 4 Common Modulation Output
User’s Guide for DG5000
4-4
default value is 100 Hz.
Notice that, this menu will be grayed out and disabled when external modulation
source is selected.
To Set Modulation Depth
Modulation depth expressed as a percentage indicates the amplitude vibration degree.
The AM modulation depth ranges from 0% to 120%. Press AM Depth to set AM
modulation depth.
When the modulation depth is 0%, the output amplitude is the half of the
specified value.
When the modulation depth is 100%, the output amplitude is equal to the
specified value.
When the modulation depth is higher than 100%, the output of the instrument
will not exceed 10 Vpp (The load is 50 Ω).
When external source is selected, AM modulation amplitude is also controlled by the
±6 V signal level of the [Mod In] connector at the rear panel. For example, if the
modulation depth is 100%, the output amplitude is the maximum when the
modulating signal level is +6 V and the minimum when the level is -6 V.
