The 10-bit DC series products are CompactPCI/PXI compliant and require an appropriate CompactPCI crate. The
digitizers are all fully programmable over the PCI bus and deliver oscilloscope-like performance. Data captured by
the digitizers can be transferred to a host processor, either in the PC, in the crate, or interfaced to the crate, over the
PCI bus. The 6U units (DC222, DC252, and DC282) can operate at 64-bit − 66 MHz with peak transfer speeds
approaching 500 MB/s. The 3U units (DC122 and DC152) work at 32-bit − 33 MHz. The digitizers occupy a single
slot of a 3U or 6U CompactPCI crate and they comply with the 3U or 6U CompactPCI standard (PXI compliant).

Acqiris digitizers are designed to provide superior measurement precision and accuracy. Key acquisition
specifications (such as DC accuracy, integral and differential non-linearity) have been optimized to deliver maximum
measurement fidelity. Careful circuit layout, custom IC’s and special packaging techniques have all been employed
to reduce overall system noise. The use of custom IC’s also dramatically reduces the total number of discrete
components required. This has tremendous benefits on reliability and also allows the modules to use a minimal
amount of power.
