DDS Sweep Function
Generator with Arb.
Model 4045
The model 4045 is a must have for anyone needing a low cost, full featured direct
digital synthesis (DDS) generator with 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 RS-232C
interfaces. 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
1MHz) 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.
