ADLINK PCIe-9814 PCI Express digitiser

ADLINK Technology has announced its high-speed PCI Express digitiser, the PCIe-9814, featuring four simultaneously sampled 80 MS/s input channels with 12-bit resolution, 40 MHz bandwidth and up to 1 GB DDR3 onboard memory. The product delivers high dynamic performance in 76 dB SFDR, 64 dB SNR and -75 dB THD, with up to 640 MBps data streaming and maximum optimisation for radar testing, power management monitoring and non-destructive testing.

The unit’s 80 MS/s sampling and 40 MHz signal bandwidth meet the requirements of medium frequency (0.1 to 30 mHz) radar signal reception from IF radar receivers. The device provides external digital trigger input for synchronous trigger radar signalling and three extra synchronous digital inputs receive radar sync pulse signals or GPS IRIG-B code. This supports radar signal markers or synchronous time stamping.

The product’s FPGA-based, 31-order FIR digital filter supports noise reduction when signal content is 20 MHz or less. Noise effects are reduced and signal visibility increased by rejecting out-of-band and background noise and unexpected high-frequency signals, all with no extra programming demands. The digital filter performs faster than on the host, with no host CPU bandwidth occupied.

The digitiser supports Windows 8 and Windows 7 operating systems and is fully compatible with third-party software. ADLINK’s measurement APIs allow easy conversion of basic voltage/time measurement results with no need for extra programming.
