The FG200 Series function generators feature sweep and modulation capabilities with outstanding ease of operation. The FG300 Series adds arbitrary sweep and simple arbitrary waveform definition capabilities, plus sequencing functions, giving you high performancealong with ease of use. Amplitude and Duty Cycle Continuously Variable. With the FG200 & FG300 Series, the output signal is not disrupted even if you continuously vary a parameter such as frequency, phase, amplitude, offset voltage, or duty cycle. Duty cycle setting range is 0% to 100%, with 0.01% resolution. The FG220 has 2 output channels. The powerful sweep and modulation capabilities of these instruments make them ideal for applications in mechatronics, and vehicle design and testing.
