The ADQ14OCT supports variable frequency clocking such as the laser K-clock in SS-OCT and supports the acquisition of high-resolution cross-sectional and volume images. The ADQ14OCT includes the following features: ADQ14OCT PCIe 200x265

  • Variable K-clock input from 10 MHz to 1000 MHz
  • Full Nyquist-rate OCT input bandwidth
  • 14-bit resolution with low spurious errors and low noise for high image quality
  • USB3.0 interface for compact designs as well as x8 Gen. 2 PCI-e interface for high-speed transfer of data to host PC
  • Embedded, real-time FFT programmable between 64 and 32k points
  • Flexible and programmable options for A-scan and B-scan triggering
  • 2 GByte on-board memory


The analog front-end is built up by four options for optimizing the ADQ14 to the specific task.

  • DC-coupled, 50-Ohm, 500mVpp OCT signal input (larger input ranges available upon request
  • AC-coupled, 50-Ohm K-clock input
  • A-scan trigger input with programmable impedance, threshold, and polarity
  • B-scan trigger input with programmable impedance, threshold, and polarity
  • USB3.0, PXI-express or PCI-express Gen. 2 x8
  • 12 Volt power supply
