I have a few minutes to play with the Bode Plot feature, I cannot find a way to access it via the buttons yet, but it is in the application folder so it is easy to get to.
* The documentation has not been updated yet, and there is no on-line FAQ yet, so I have to fly blind. Hopefully they will have something posted on the support site soon, currently the only help is the little picture on how to connect everything.
* The signal source seems to be locked into internal AWG Ch 1, the option to change it is greyed out even if AWG Ch2 is on. So I don't have a way to change the source, perhaps if one attaches a compatible Rigol AWG via USB, the option could become active, I don't know for sure.
* With the internal AWG, the max frequency is 25 MHz, no change from the native AWG spec.
I will add more when I have more time to play with it.
