I am building a plasma source and need a 13.56MHz sinusoidal signal with at least 100 watts of power. Preferably 400watts. I understand the function generator alone cannot due this, and that shielding will need to be considered as not to violate any FCC related rules. It would be nice to have at least 30MHz of bandwidth, but I can make due with 20Mhz.
On one channel the 13.56MHz signal is bursted with a set amount of cycles. That signal would go through some kind of amplification then two tunable capacitors, and ultimately to an inductive water cooled coil wrapped around a glass cylinder where the plasma is produced.
The second channel will be used to generate whatever waveform I need independently of the other channel.
I have recently purchased a Rigol 1054z and a Rigol 832 and those decisions was largely based off of what I've read on these forums when lurking, and of course, Dave's reviews.
I am now considering a Rigol DG1022 or DG1032Z for this application. Are these as good of a bang for your buck as the other Rigol equipment I have purchased? Also, what is the least expensive way for me to amply these signals as well as tune the impedance as to minimize the forward and reflected power of the 13.56Mhz? I would have to monitor these values as well. (cheap digital SWR meter that can handle 56dbm?)
