BK Precision 4045 - 20MHz DDS Sweep Function Generator with Arb Function
he 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. 20MHz Frequency Range (sine & square only) Sine, Square, Triangle & Arbitrary Waveforms Modulation in both AM & FM Lin or Log Sweep Function Adjustable Duty Cycle Adjustable DC Offset Bright Informative LCD RS-232C Interfac
