The prototype of 150-watts RF generator can operate as Stand-alone in manual mode, or can be programmed via an external data acquisitioning system such as National Instruments Compact RIO FPGA systems or similar products for higher flexibility and ease of operation.
Standalone mode: Provides up to 150 watts of pure sinewave at 380/480KHz (fixed) RF energy that can be adjusted through front panel knob. It also provides parameter monitoring such as Power, Impedance and ablation time. Figure 1, depict the simplified block diagram of the 150W RF generator system in Auto and Manual modes.
Auto mode Features:
· Programmable power control from fraction of a watt up to 150 watts
· Programmable Impedance setting from 25 up to 500 Ohms or any desired value sets by the operator
· Programmable
ablation time from 1 second up to any value set by the operator
· Mono or bipolar operation
Operational modes:
· Temperature, Power, Impedance, pulse or combination of all
· Parameter monitoring including, Power, Impedance, Current, Temperature and Pulse
Width
· Ease of graphical programing in LabVIEW FPGA technology as well as MATLAB
or other scientific programming languages
· Elaborate set of data collection/playback
and analysis utilities
