GW Instek SFG-830 - MHz Arbitrary Function Generator
The SFG-830 Series 30MHz Arbitrary Function Generator is one of the most versatile and highly qualitative signal generators utilizing DDS techniques. They not only offer the standard generator functions but also provide accurate modulations, sweep, and arbitrary waveform generation. The free editing software allows professional users to obtain, edit, or create frequency and amplitude characteristics as desired through RS-232C interface or GPIB interface (SFG-830G). The SFG-830 Series is suited to simulate all signals encountered including both ideal and abnormal conditions. For applications, such as product design, manufacturing testing, automotive, and sensor stimulation, the SFG-830 Series is the best solution provider for generating arbitrary waveforms.
