Acqiris digitizers are available in two popular industry standards. The DP series digitizers are PCI modules that plug
directly into a vacant PCI slot in a PC. The PCI Bus is a well-defined industry standard. The 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 using a 32-bit bus operating
at 33 MHz, at speeds up to 100 MB/s. The U1071A-FAMILY can use the PCI bus at 66 MHz thus allowing transfer
rates up to 200 MB/s.
DC1XX series digitizers occupy a single slot of a 3U CompactPCI crate and they comply with the 3U Compact PCI
standard (PXI compliant). DC2XX series digitizers occupy a single slot of a 6U CompactPCI crate and they comply
with the 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 (15 W typical for a single channel 1 GS/s card).
The block diagram above is a simplified representation of a single channel unit. For complete technical specifications
concerning your particular digitizer please refer to the product's Specifications & Characteristics. In addition, we
maintain up-to-date versions of all product data sheets on our web site (http://www.agilent.com/find/acqiris). The
data sheets are available in pdf format and are best viewed using Adobe Acrobat software. If you have trouble
accessing our web site, or viewing the data sheets, please contact your nearest sales office.
