DDS Function Fenerators (10MHz & 20MHz)
Offering a high-quality DDS function generator at a significantly lower price. DDS (direct digital synthesis) is a technique for generating waveforms digitally using a phase accumulator, a look-up table and a DAC. The accuracy and stability of the resulting wave forms is related to that of the crystal master clock. When correctly engineered, the DDS generator offers not only exceptional accuracy and stability but also high spectral purity, low phase noise and excellent frequency agility. Unlike some other generators which only provide digital control of frequency, every function is digitally controlled enabling complete instrument set-ups to be stored, or full remote control to be implemented. Features- • 0.001Hz to 10MHz or 20MHz frequency range, 6 digits or 1mHz setting resolution. • 1ppm stability and better than 10 ppm absolute accuracy for one year. • Sine, square, triangle, positive pulse and negative pulse waveforms. • Low distortion, high spectral purity sine waves. • Internal sweep, linear or logarithmic, full range phase continuous, adjustable marker. • Modulations modes of gated, AM, FSK and tone switching; built-in trigger generator. • 5mV to 20V pk-pk output from 50Ω or 600Ω; plus, multi-function auxiliary output. • Storage for up to nine complete instrument set-ups in non-volatile memory. • Fully programmable via RS-232 or USB interfaces. • Ease of use Applications- • Frequency or period entry • Flexible amplitude entry • Synchronisation • Tone Switching • Modulation of modes (sweep, Gated, AM, FSK) Technical specifications- • Display: 20-character x 4 row alphanumeric LCD • Data Entry: Keyboard selection of mode, waveform etc.; value entry di rect by numeric keys or by rotary control • Stored Settings: Up to 9 complete instrument set-ups may be stored in battery-backed memory. • Size & Weight: 260(W) x 88(H) x 235(D) mm; 2kg (4.5lb) • Power: 100V, 110-120V or 220-240V ±10% 50/60Hz, adjustable in ternally. 40VA max.
