Of course, the basic waveforms are pre-programmed. In addition to using the front panel keypad for programming, the program can be debugged on a computer and sent via USB or RS-232. One feature that makes the generator particularly interesting is its ability to reproduce all types of analog and digital modulations: AM, FM, PM, FSK, and perform sweeps and bursts. It also has an external modulation input and an external clock input. A 6-digit frequency counter up to 200 MHz is included.
The GF-858 dual arbitrary waveform generator, together with the FA-853 programmable power supply and any of the OD-6XX series digital oscilloscopes, forms a workstation that meets the needs of even the most demanding electronics developer.
