Spectrum Instrumentation has released a new firmware option for its range of versatile 16-bit Arbitrary Waveform Generators (AWGs) with sampling rates up to 1.25 GS/s and bandwidths up to 400 MHz. The new option allows users to define 23 DDS cores per AWG-card, that can be routed to the hardware output channels. Each DDS core (sine wave) can be programmed for frequency, amplitude, phase, frequency slope and amplitude slope. This enables, for example, the control of lasers through AODs and AOMs, as often used in quantum experiments, with just a few simple commands – instead of making large data array calculations. The DDS output can be synchronized with external trigger events or by a programmable timer with resolution of 6.4 ns.

With the ability to switch between the normal AWG mode (which generates waveforms out of pre-programmed data) and the DDS mode (which needs only a few commands to generate sine wave carriers), the Spectrum AWGs are highly versatile and can be adapted to almost any application. In DDS-mode, the AWG acts as a base for the multi-tone DDS. The units built-in 4 GByte of memory and fast DMA transfer mode then allows the streaming of DDS commands at a rate as high as 10 million commands per second. This unique capability provides the flexibility to perform user-defined slopes (e.g. s-shaped) as well as various modulation types (e.g. FM and AM) with simple, easy-to-use, DDS commands.

The DDS option is available now for the full range of M4i.66xx PCIe cards, M4x.66xx PXIe modules, portable LXI/Ethernet DN2.66x units and multi-channel desktop LXI/Ethernet DN6.66xx products by Spectrum Instrumentation.
