This project is to control Velleman PCGU1000 function generator with USB port. For communications trough USB, libusb unit is used. Directory of program, which uses this project, must contain file pcgu1000.bit (microcode for generator). This file can be also downloaded from Velleman's site. Currently it can control all parameters of generator like: on/off, -40dB, attenuator, offset, amplitude fine tune, filter, freq, sweep, waveform and so on. Standard signal waves like, e.g., sine, triangle and rectangle are available; other sine waves can be easily created. The signal waves are created in the PC and produced by the function generator via DDS (Direct Digital wave Synthesis). All outputs are galvanically separated from the PC in order to avoid measuring problems. Some features and specifications are:
