·         theneff system 470 (s470) das is a complete, low cost moderate-speeddas for use in computer-based applications. the s470 is designedprimarily for computer automated data ac in testfacilities, laboratories and industrial plants or wherever amoderate-speed das is re

·         thes470 is designed to accept analog inputs ranging from 5mv to 10.24vfull scale in 12 programmable steps. signal conditioning forsensors such as strain gages, rtds, potentiometers andthermocouples is supplied by standard s470 function cards thuseliminating the need for external sources. other function cardssupport digital i/o, frequency measurement and analogoutput.

·         s470consists of a 7-inch high, 19-inch wide enclosure with powersupply, backplane wiring, i/o control logic printed circuit card,analog subassembly printed circuit card and 16 i/o card slots thataccept any combination of s470 function cards. a control/displaypanel is optional and an expansion assembly is available to extendfunction card capacity to 32. the maximum number of channels ordata points to be serviced depends on the type of function cardsused. thirty-two 16-channel multiplexer cards, for example, provide512 channels of analog input while a full complement of 32-bit ttlinput cards accommodate 1024 single data points.

·         theseries 600 is neff's top-of-the-line data ac systemproviding the utmost in performance, accuracy and convenience.featuring leading-edge technology and innovative design, series 600brings extensive automation and complete programmability to thetesting laboratory.

·         thekey to series 600's high performance is the effective combinationof fully programmable preamp/filters, programmable post amplifier,sophisticated microprocessor-controlled calibration circuits andthe amplifier-per-channel data acue that realizesthe lowest noise level and highest common mode rejection obtainablein a data ac system.

·         programmablegain over the full dynamic range
with programmablegain, test setup time is greatly reduced as is the bother andconfusion of manual switch settings. in series 600 the range ofeach channel is programmable from +/-5mv full scale to +/-10.24vfull scale in 12 binary steps.

·         preampsinclude programmable filter
two types of inputpreamps are available in series 600 to allow both static anddynamic measurements. both have programmable filter cutofffre of 1hz, 10hz, 100hz and 1khz. low-level differentialpreamps (620650 and 620654) have 2-pole and 6-pole butterworthfilters, respectively.

·         thesample and hold preamp (620654) permits simultaneous sampling ofmultiple low-level input channels and is used where minimumchannel-to-channel skew is re both preamps have fullyguarded inputs and operate from grounded or floating signalsources.

·         automaticcalibration
on command the internal microprocessortakes over control of the series 600 and begins a sequence of stepsto derive and store calibration factors for each channel. thecalibration data is stored in on-board memories and during run modeare summed with the post amplifier output voltage to obtain fullycalibrated signals for conversion by the adc.

·         theautomatic calibration procedure results in static accuracy of(0.02%
