Acqiris has introduced a family of PCI 12-bit ADC digitizer cards that are PCI-compliant and allow users to reduce automated testing times by a factor of 10 to 100 compared to conventional test instrumentation.

The PCI 12-bit family consists of a high-end Model DP310 and two entry-range models, all delivering signal-to-noise ratios (SNR) up to 64dB, spurious-free-dynamic-range (SFDR) better than 78dB, and a time base with precision better than 2ppm.

The DP310 provides a direct high-frequency input with 300MHz bandwidth for under-sampling measurement, as well as a fully buffered input with 100MHz bandwidth. To accurately digitize high-frequency signals, the DP310 has a sampling rate of up to 400MSps and 64Kpoints of on-board memory. Additional specifications include total harmonic distortion of <-73dB, a low noise floor spectrum at -90dB, and effective bits of more than 10.

The DP308 samples at up to 200MSps with 100MHz bandwidth, while the DP306 samples up to 100MSps with 50MHz bandwidth. Both cards have 32Kpoints of on-board memory and are targeted for applications in the automotive, ultrasound, and lidar domains. Additionally, the devices' TV trigger capability (NTSC or PAL/SECAM) makes them suitable for use in video signal applications such as those based on fast CCD cameras for imaging readout.

The DP series includes Control I/O that provides several high-speed front-panel analog and digital interfaces.
