Spectrum DN6.66xx series arbitrary waveform generators

Spectrum’s DN6.66xx series of arbitrary waveform generators (AWGs) allow engineers to select from an extensive range of products specifically designed for multichannel signal generation applications.

LXI compliant, the instruments are easily integrated into any test system by a simple Ethernet connection to a PC or local area network (LAN). Using 16-bit digital to analog technology (DAC), the AWGs offer from six to 24 fully synchronous channels, output rates up to 1.25 GS/s, analog bandwidth as high as 400 MHz, large onboard memories (up to 1 GSa/ch) and generous output voltage ranges of up to ±5 V into high impedance and up to ±2.5 V into 50Ω.

All the output channels are clocked and triggered synchronously so they maintain a constant, interchannel clock phase relationship. The clocking system uses a precision phase locked loop (PLL) control process that can be generated internally or, alternatively, from an external clock or reference. Time skew between the channels is also minimised with the maximum skew, between all channels, being less than 130 ps.

To allow the generation of long and complex waveforms, the AWGs combine their large onboard memories with a number of operating modes such as Single-Shot, Loop, FIFO, Gating and Sequence Replay. Sequence Mode cuts the memory into segments of different length and combines them with a sequence of commands including loops for more efficient memory use.

The instruments are self-contained and come with all the tools necessary to generate an almost unlimited variety of waveforms.
