The25 MHz dual channel multifunction generator GF-858 from Promax combines Arbitrary Waveform and Function Generator, and uses DDS (Digital Data Storage) technology to offer two programmable signals in a 4 inches LCD colour screen. All basic waveform are pre-programmed.
Besides using the front panel keyboard for programming, the program can be enhanced in the PC and send it through USB or RS-232.
One feature that makes the GF-858 especially interesting is the possibility of playing all types of analog and digital modulations: AM, FM, PM, FSK and perform sweeps and burst. The GF-858 also has an input for external modulation and external clock input. It includes a 6 digits frequency counter to 200 MHz.
