Hello
Most likely you have set the load gain as "same as source" which is
50 ohms by default. The driver will automatically generate twice the voltage so
that you get the requested voltage at the load. This is because you have a load
and source impedance of the same value which will act as a voltage divider.
In NI-FGEN driver, there is a property node "Load Impedance". You can set the value for this property node as "1M" and it will also solve the problem. Look at the picture.
Hope this helps,
