PCI Express based arbitrary waveform generator boards are well suited for demanding signal processing applications.
Strategic Test is claiming a world's first for its range of PCI Express based arbitrary waveform generator (AWG) boards With synchronous multichannel capability, the boards are well suited for demanding signal processing applications that include I and Q signal generation, radar system development, communications testing, laser positioning, and HDTV signal generation

The Zeon StrongARM computer board is optimised for embedded industrial and automotive applications.
Ultra-fast sampling board runs up to 125Mbit/s
The UF.7021 is a full-length PCI board with 64 digital input or output channels that can simultaneously capture and replay signals at a maximum sample rate of 125Mbit/s.
There are four new AWG boards in the UF2e-6030 series with a choice of one, two or four channels and 14bit resolution: the UF2e-6030 is a single-channel board capable of 125Msample/s; the two channel UF2e-6031 provides 125Msample/s on each channel; and the UF2e-6034 offers 125Msample/s on two channels or up to 60Msample/s on four channels.
Each channel has its own 14bit D/A convertor 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 signal-to-noise ratio (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 1Ksample/s and the maximum rate of DAC.
The driver automatically adjusts the onboard hardware to provide the closest sampling rate possible.
This value can be returned to the user program.
A novel feature is that 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 2Gsample through a proprietary onboard DIMM module.
As with all UltraFast AWG boards, the signals can be downloaded to onboard memory, output one time, or continuously until stopped, or continuously streamed gap-free from the host PC RAM or hard disks.
Prices start at US $4190.
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.
