[now obsolete, replaced by ACQ196CPCI] Commercial Off The Shelf - a commercially available product. Generally a card conforming to a standard like Compact PCI D-TACQ Solutions Ltd designs and manufactures a range of innovative products with the defining characteristic of "High Performance Data Acquisition". A large programmable logic device. The FPGA program image on D-TACQ products is loaded from flash memory at boot time, allowing for easy in-system upgrade. Integrated Circuit that includes a microprocessor and other support devices such as Ethernet, DRAM controller, peripherals and crucially FPGA fabric in a single package Industrial implementation of the PCI bus, based on standard Eurocard modules. CompactPCI industrial formfactor standard using pci electronics standards available in 3U and 6U sizes. IPC industrial formfactor based on standard desktop pc sizes. Fits 19 inch rack, typically uses a PCI passive backplane for ruggedness A programmable automation controller (PAC) is a compact controller that combines the features and capabilities of a PC-based control system with that of a typical programmable logic controller (PLC) ADC device converts input voltage to digital word. DAC device converts digital word to analog voltage. INL ADC figure of merit. DNL ADC figure of merit LSB the step size of the smallest meaningful bit in the digital word. A low pass filter designed to limit input bandwidth to below Nyquist. Frequency components above Nyquist that would otherwise cause aliasing are attenuated CMRR is the ratio of signal to common mode noise THD is the standard measure of distortion in the signal SINAD ratio of signal to noise and distortion SFDR the dynamic range available between a full scale signal at zero dB and the highest spike up from the noise floor. SNR standard measure of system noise performance A measure of the quality of an analog to digital converter. ENOB is a function of SNR. Systems may use oversampling to increase ENOB. Digitizers with fast ADC converters may sample at several times Nyquist in order to reduce the requirement for anti alias filtering and to increase SNR and therefore ENOB. BW Band Width in MHz Arbitrary Waveform Generator. (ARB). Generates analog output waveform based on memory lookup table. Digital control method sets average output voltage by varying the mark:space ratio of a digital waveform To Be Advised - preliminary value. If you come across one of these in our documentation, please ask us to explain. It is possible that the document is old and the value is know available. high performance pushfit connector SMA (SubMiniature version A) connectors are coaxial RF connectors developed in the 1960s. Standard formfactor for plug in duplex fiber optic transceiver. 68 way very high density connector. Compatible with parallel SCSI-3 cabling Mega Samples Per Second - D-TACQ always quote MSPS per channel, not aggregate. kilo Samples Per Second - D-TACQ always quote kSPS per channel, not aggregate. FS full scale reading AO Analog Input - external analog signal to be digitized. In a D-TACQ product, this is typically a differential input, and invariably multiple AI channels are sampled simultaneously. The voltage on the input is sampled and turned into a number that is subsequently used by a computer. AO Analog Output - converts a computer numeric value to a voltage. In a D-TACQ product, this output updates simultaneously with a number of other AO channels DI Digital inputs feed direct to the FPGA for timing. DO : digital output port DIO registered digital input/output with programmable direction MOQ minimum order quantity related to minimum economic batch size DDR Double Data Rate - double edged clocked DRAM for increased bandwidth differential (input) achieves high noise immunity by reporting difference of two signal lines of opposite polarity PXI defines additional signaling on top of the Compact PCI standard. Vref is the analog reference voltage used to scale DAC output RF - radio frequency applications 1..100 MHz bandwidth ATE automated test equipment SAR - ADC control alogorithm ramps digital value stepwise until analog match is obtained Flash ADC: D-TACQ uses pipelined multistage FLASH converters = max speed but with sample latency. Defines features High Speed and Good Accuracy SBC - self contained computer system in single slot standard formfactor FIR a digital filter architecture with guaranteed stable response to impluse Input Sample Rate - front end ADC clock rate in an oversampling system. Typically decimation is used to reduce the output sample rate. Typically some DSP technique like FIR filtering or digital integration is used to increase the processing gain of the system. Output Sample Rate - effective output sample rate from an oversampling digital system. Typically decimation is used to reduce the output sample rate. Typically some DSP technique like FIR filtering or digital integration is used to increase the processing gain of the system.
