CompactPCI Boards CompactPCI Boards AcPC341 Simultaneous A/D Conversion Analog Input AcPC341 boards provide fast, high resolution, simultaneous A/D conversion of eight channels. This board is ideal for high-speed data acquisition. A large memory buffer reduces CPU interactions for increased overall performance. These boards have sixteen analog inputs which are sampled as two eight-channel banks. Eight CompactPCI bus Compliance Specifications Meets PCI spec. V2.2 and PICMG 2.0, R3.0. A/D converters (ADCs) permit simultaneous Analog Inputs Data transfer bus: Slave with 32-bit, 16-bit, and 8-bit data conversion of all eight channels in a bank. All Input channels: 16 differential. transfer operation. 16 channels share two generous 512-sample A/D resolution: 14 bits. Interrupts (INTA#): Interrupt A is used to request an interrupt. memory buffers. Conversion of each bank requires Input range: ±10V. Plug-and-Play: The system maps the base address into the only 8µS, and all 16 channels can be sampled in Maximum throughput rate: PCI bus 32-bit memory space. just 16µs. Eight channels can be simultaneously acquired. One channel: 125KHz (8µS/conversion) Flexible configuration options give you extensive control Ordering Information 8 channels (same bank): 1MHz (8µS/8 channels) over the conversion process. The channels or bank to be AcPC341 16 channels (high & low banks): 1MHz (16µS/16 ch. at converted, timing, scan mode, and other parameters are Analog input board maximum 2.2K ohm source resistance). user-programmable. Interrupt support adds further AcPC341E Data sample memory: Two 512-sample memory buffers control to interrupt upon a programmable threshold Same as AcPC341 plus extended temperature range allows writing to one buffer while reading from the other. when the data in memory exceeds the set threshold. A/D triggers: Internal timer, external, and software.
