Two 8-bit resolution arbitrary waveform generator cards with up to 4 gigasamples of onboard memory are available from Strategic Test Corp. (Woburn, MA).

The UF2-6110 has two synchronous 125-MS/s output channels, and the UF2-6111 offers four channels on a single PCI card. Both cards offer 64 megasamples of signal memory that can be increased to 4 gigasamples using a proprietary DIMM module on the card. The cards are suited for Radar and I&Q signal generation. A multiple relay option allows a series of high-speed waveforms to be generated with automatic re-arming of the trigger by hardware to ensure a high pulse repetition frequency (PRF). T

he choice of two or four synchronous channels per card enables matching I&Q generation without requiring a second card. Each channel contains a 125-MS/s, 8-bit DAC and three Butterworth reconstruction filters with bandwidths of 25 MHz, 5 MHz, or 500 kHz. A "no-filter" setting can be selected. Measured dynamic specifications include SNR greater than 60.9 dB, THD less than 69.1 dB, and SFDR greater than 71.9 dB. The cards employ a 66-MHz/ 32-bit PCI-X interface that can stream data continuously from the host PC at rates up to 225 MS/s. Long-duration signals can be generated at lower output rates. Drivers for Microsoft Windows XP64, XP, 2000, and Linux are included.
