AlazarTech announced the release of ATS9350, a 12-bit, 500 MS/s, dual channel waveform digitizer based on the eight-lane PCI Express bus. The RoHS compliant instrument features a dual-port on-board acquisition memory buffer, which enables very fast, sustained data throughput to computer memory. Benchmarks run by the manufacturer show rates as high as 1.4 GigaBytes/s (not GigaBit/s) for sustained throughput over many hours. It also offers the ability to be externally clocked at frequencies as high as 500 MHz and as low as 1 MHz. This is appropriate for applications such as Optical Coherence Tomography (OCT) that require sampling to be synchronous with a non-uniform clock generated by a swept source laser. The latest generation of swept-source lasers output clocks that can be as fast as 400 MHz and as slow as a few MegaHertz. The ATS9350(R) contains a large, Stratix II GX FPGA from Altera. Approximately 30 percent of the FPGA is available for customization, such as FFT, averaging etc. Two simultaneous analog inputs can each be sampled at rates up to 500 MS/s (one 12 bit, 500 MSPS ADC per channel), providing Signal to Noise Ratio in excess of 60 dB. Each channel can have up to 2 Gs of on-board, dual port acquisition memory buffer. The unit occupies one half-length PCI Express x8 or x16 slot.
