UF2e-6030

Strategic Test has developed what it claims as the world's first PCIe-based arbitrary waveform generator (AWG) boards.

With synchronous multichannel capability, the AWG boards are well suited for demanding signal processing applications that include I&Q signal generation, radar system development, communications testing, laser positioning and HDTV signal generation.

Strategic Test has added four new AWG boards in the UF2e-6030 series with a choice of 1, 2 or 4 channels and 14bit resolution. These include UF2e-6030 device (one channel, 125MSPS max.), UF2e-6031 (two channels, 125MSPS each channel) and UF2e-6034 (fours channels, 125MSPS on two channels or 60MSPS max. on four channels).

Each channel has its own 14bit DAC to ensure synchronous output and a choice of three reconstruction filters (5th and 4th order Butterworth lowpass) giving bandwidths of 25MHz, 5MHz or 500kHz. A no-filter option is also software-selectable.

Typical dynamic specifications include SNR of better than 61dB, total harmonic distortion (THD) of less than 71.5dB and spurious-free dynamic range (SFDR) greater than 72dB.

As with all UltraFast instrument boards, the advanced sampling clock design consisting of a hardware divider and PLL allows the user great flexibility in defining their optimum sampling rate. In the case of the UF2e-6000 boards, the output rate can be freely selected between 1KSPS and the maximum rate of DAC. The driver automatically adjusts the on-board hardware to provide the closest sampling rate possible. This value can be returned to the user program.

The board can be equipped with a second user selected quartz crystal oscillator for applications that require a highly accurate specific output rate.

The boards are supplied with 32MSamples of signal memory as standard, but can be expanded to 2GSamples through a proprietary onboard DIMM module.

As with all UltraFast AWG boards, the signals can be downloaded to on-board memory, output one time, or continuously until stopped or continuously streamed gap-free from the host PC RAM or hard disks.

Several options are available for each board, allowing the user to customize the instrument. Users can chose for onboard memory densities of 32-, 64-, 128-, 256-, 512-, 1,024 or 2,048MSamples. The boards also offer multiple replay (memory segmentation) and gated sampling (output clock controlled by external TTL signal).

Moreover, the boards feature digital outputs (2bits per DAC, synchronous) and Star Hub option (synchronization of up to 5 or 16 boards, or 5 to 16 PCs which can be used with digitizer and digital I/O boards to create mixed mode systems. Other options offered include BaseXIO which adds 8 asynchronous digital I/O lines to the board and an amplifier board that increases output range from 3V to 10V.

Strategic Test also provides comprehensive software support by offering Software Development Kit's for Windows Vista and XP64, XP, 2000, NT and 98, Linux drivers for RedHat, Suse, Fedora and Debian, Matlab, LabVIEW, Agilent-VEE, LabWindows/CVI and DASYLab.

Pricing for the device starts at $4,190. All UltraFast boards are supplied with the free-of-charge SBench software that allows users to generate and output waveforms without programming. SBench is available for both Windows and Linux.
