Tel.: 714.921.9095
USB connection
The model 4045 DDS Function Generator is a
must-have for anyone needing a low cost, full
featured direct digital synthesis (DDS) function
generator with arbitrary waveform capabilities. The
4045 has a menu-driven front panel interface that
includes a large, easy-to-read graphical LCD display.
Waveform parameter changes and data entry can be
made using the rotary knob or via the built-in USB
interface. The unit generates superb quality
waveforms with high signal precision and stability.
It provides sine & square wave outputs over the
frequency range from 0.1 Hz to 20 MHz in one
extended range (triangle/ramped wave outputs to
2MHz). Arbitrary waveforms can be edited from
scratch or by modifying standard waveforms. A full
range of triggering capabilities is available, including
internal-external trigger source, gated and burst
modes of operation.
