Not confusing but pointless without referring to specific circuits.
A RF generator is usually converting DC into RF power. At some parts of the circuit, a superimposed DC voltage will be present. If it's transferred to the RF output - depends.
I suggest to narrow down the question a bit. "RF generator" can be nearly everything, a simple one-stage oscillator, a full featured lab instrument, a radio transmitter, ...
The unit is rf generator model (ENI Model#: DPG-10). All been stated on the output are RF_output: 1.25KW and DC_output: 500V....That's the reason i has been confused. Why rf gen have dc output...thanks.
Like FvM, none of my RF generators have a DC output but "RF generator" could refer to ANY equipment producing a signal so your question was not clear. I'm guessing the DPG-10 is producing RF for plastic welding which is a very specific application and it would be part of a bigger set of equipment. Almost all other RF generators do not produce DC at their outputs and in any case do not use anything like as high as 500V internally.
Does it have some kind of explanation why they have it labelled RF_Output: 1.2KW. This shouldn't be like RF with high freq...but maybe because of power relationship..not sure really.

Hello FvM...yes i agree with you....sometime people raised question without much detailed info. Well, can you please give more ideas about RF/DC combination? Still blur to me this RF/DC thing...If you have some links to explain this...thanks.
