DDS Signal Generator-SG100x

Overview

SG100x is a signal generator with FPGA technology, which is based on Direct Digital Synthesis(DDS). It can output the TTL with high stability and measure the frequency accurately. The output signal amplitude and DC bias can be adjusted. SG100x is very easy to use for studio, technicians and enthusiasts.

SG100x series we provided 3 kinds of different frequency.

Max Frequency 2M : SG1002(default)

Max Frequency 3M : SG1003(Sold Out)

Max Frequency 5M : SG1005

Max Frequency 10M : SG1000
