Description
ADRE Sxp Softwareand the408DSPi(Dynamic Signal Processing Instrument) makeup a highly scalablesystem for multi-channelsignalprocessing and data acquisition.
Unlikeother general-purposecomputer-based data acquisition systems, ADRE Sxp and the408DSPiare specifically designed for real-timehighly parallelsignal processing and presentation. This extremely versatilesystem incorporates thefunctionality ofmany types of instrumentation, such as oscilloscopes, spectrum analyzers, filters, signalconditioners, and digitalrecorders into a single platform. Thesystem is designed specifically for secure corporatenetwork environments, allowing it to operate remotely across a LAN/WAN, or storedata in full“standalone”modewithout an additional/externalcomputer. Additionalequipment is seldom, ifever, needed. Thesystem’s real-timedisplay capability permits it to continuously display data independently ofdata being stored to permanent memory. For established ADRE system users, ADRE Sxp also supports allprevious ADRE for Windows databases.
An ADRE Sxp data acquisition system consists of:
•408Dynamic SignalProcessing Instrument(s).
•ADRE Sxp client software, ADRE Quick Configuration software.
•A computer system capableofrunning ADRE Sxp software.
The408DSPiis fully portableor can berack mounted allowing convenient operation in test stands, on-site, or at remote locations. The408DSPi’s highly configurabledesign supports virtually allstandard and non-standard input types including both dynamic transducer signals (such as thosefrom proximity probes, velocity transducers, accelerometers, force

hammers, dynamic pressuresensors), and static signals (such as process variables from transmitters and distributed controlsystems). For rotating machinery applications, users can providea Keyphasor or other speed input signal(such as that from a magnetic or optical transducer) to drivesynchronous sampling and order tracking. For structuralanalysis needs, impact testing using forcehammers is supported. Thesystem also supports multiple triggering modes for automated data acquisition, allowing you to usethesystem as a data or event logger without an operator present.
TheClient-Server architectureallows multiple softwareclients to operateand simultaneously view data from single/multiple408DSPi systems simultaneously, permitting users to independently view data in thefundamental measurement units oftheir choice. Software installation and configuration arequick and easy, allowing mass configuration ofmultiple channels with minimaluser intervention. Configuration templates and softwarefurther simplifies theprocess, allowing theuser to installthesoftware, producea configuration, and begin capturing data in minutes.
408 DSPi Overview
Each 408DSPisupports up to 4sampling cards for up to 32 channels ofdata acquisition. The 408DSPibasesystem uses internalclocks and simulated speed/Keyphasor signals to support both asynchronous and synchronous sampling for allchannels. Speed Input/Trigger cards support up to 3 independent speed input channels for externalspeed inputs. Each Speed Input/Trigger card uses 1availableslot, and the 408DSPican usea maximum of2 Speed Input/Trigger cards simultaneously providing up to 6physicalspeed inputs and 6simulated speed inputs. Theuser can assign any speed input (KPH) to any channelin a 408DSPi. Most signalprocessing and sampling parameters can bechanged “on-the-fly”without interrupting data collection.
The408DSPiarchitectureprovides flexible hardwareconfiguration. Users can insert sampling cards into thechassis as required. Slots 1through 4support allstandard sampling
cards. Slot 5is intended specifically for the DigitalReplay card as wellas futureoption cards.
Thestandard Dynamic Sampling and Speed Input/Trigger cards providefullsupport for structuralanalysis and impact testing. Data can beanalyzed natively or exported to 3rd party applications ifdesired.
The408DSPifront panelcontrols and displays basic functions and data. Users can directly initiatemanualsamples and triggering from thefront panelwithout using ADRE Sxp software. Thefront panelLEDs indicates sampling and trigger status and activity. Users can download multiplesampling configurations to the408DSPiand later select them for usefrom thefront panel.
8-Channel Dynamic Sampling Card (168905 – AA)
The8-channeldynamic sampling card is an extremely powerfuland flexiblesignal processing engine. Along with theanalog front-end conditioning, theuser can configure most transducer inputs, with positiveor negativebias, whilemaintaining maximum signalinput range. An array ofDSP processors and 24-bit ADCs providemaximum resolution. Input signals can beeither ACor DCcoupled, and users can independently defineupper and lower input voltagelevels along with full-scale rangeand transducer scalefactor.
Thesampling card can providea variety of data depending on theconfiguration and user needs. Each channelcan providemultiple “static”variables including:
•Direct amplitude.
•Bandpass amplitude.
•1Xand 2XAmplitudeand Phase, and up to 4additionaluser defined nXvectors including amplitudeand phase.
•Average& instantaneous gap or bias voltages.
•Multiplespeed values.
•Adate/timestamp.

In addition to thestatic data, each channelcan provideup to 4user-defined dynamic waveforms. Users can configurewaveforms for simultaneous Synchronous and/or Asynchronous sampling, with different sampling rates and/or frequency spans. The sampling card supports up to 2 different synchronous sampling rates simultaneously. Time-Synchronous Averaging can also be enabled for allsynchronous waveforms. In addition, thecard can also sampleand store theraw time-continuous data for each channel. Allchannels within thesystem are always sampled simultaneously, are synchronized, and areinitiated based on a set ofuser defined events.
3-Ch Speed Input/Trigger Card
(168906 – AA)
The3-channelspeed input/trigger card supports a variety oftransducer inputs and signalconditioning needs including; proximity, magnetic, optical, and laser pickups. Transducer power for both opticalpickup and ± 24Vdc proximity is also availableifneeded. For impact testing applications, theforcehammer output can beconnected directly to this card providing leveltriggering and fulldynamic waveform capture. Thecard integrates a rich set ofconfigurableanalog signalconditioning tools including: input gain, voltageclamping, inversion, rising or falling edgetrigger, auto/manualthreshold, and hysteresis. The user can associatea programmablespeed input (Keyphasor) multiplier/divider for each channelindependently, definediscretevalues for events per revolution, or, a finalratio, whichever is moreconvenient. Each channel can haveup to threeseparate“stages”of multiplier/divider ratios. Trigger/speed input channels providefulldynamic sampling, completewith static and waveform data, availablefor real-timeviewing and storage.
Each channelalso includes a buffered output, allowing theuser to select either raw, conditioned analog, or TTL outputs. The buffered outputs areindependent ofthesignal being used for processing.
Digital Replay Card (168907 – AA – BB - CC)
TheDigitalReplay Card provides simultaneous synchronous and asynchronous internal digitalreprocessing and playback ofall channels in the408DSPi. Thereplay card maintains exceptionalaccuracy and precision in thesignalreprocessing that far surpasses thecapabilities ofother equipment and reprocessing techniques. Thedigitalreplay card can play back raw data for allchannels simultaneously including Keyphasor/speed and dynamic sampler inputs. Users can modify allsampling parameters on a KPHchannel when replayed, and fully manageand recondition the gain, inversion, clamping, and other characteristics ofKeyphasor signals. This provides theability to controltriggering edges and thresholds as reprocessing and analysis requires. On standard dynamic channels, users can modify most sampling parameters. As an example, users may add or modify waveform assignments, variablegeneration, filtering options, frequency span, and Keyphasor assignments that did not exist in theoriginal configuration reprocessing thedata. Additionally, users may add or modify all sampling criteria and triggering parameters. Fullscalerange, coupling, and transducer type cannot bealtered for standard dynamic channels. TheDigitalReplay card occupies Slot #5ofthe408DSPiand does not reducethe number ofchannels availablefor data collection.
With theaddition ofAnalog Output Replay Card theuser may send up to 32 channels of recorded signals through data ports to auxiliary equipment. Thesesignals areanalog recreations oftheoriginaldata observed by ADRE. TheReplay Modulecan beordered with or without theAnalog Output Replay Card. Existing Replay Cards can bemodified to includetheAnalog Output featureby sending thecards to Product Repair at Bently Nevada.

Transducer Power Supply Card (168908 – AA – BB)
Thetransducer power supply card provides power for a widevariety ofdisplacement, velocity, acceleration including ICP accels, force hammers, and other transducer types used in field and test stand applications. This card can simultaneously power up to 32 transducers in various combinations, and provides direct physicalconnections for up to 16transducers, eight ±24Vdc transducer systems and eight constant current transducer systems. Field connection cableand adapter accessories accommodateadditionaltransducer connections.
In addition to ±24Vdc selections, thecard provides ±positiveand negativebias selections for constant current applications, allofwhich can beused simultaneously, to providea highly flexiblepower sourcefor most any need. Users can configuretransducer power bias in blocks offour (4) directly from thecard without theneed for specialtools, jumpers, or software.
Each output provides individualshort-circuit protection, current regulation, and indicators for power status and voltage/current selection (completecard status is provided within ADRE Sxp client software). Also, this card can occupy a dedicated option slot and leaveall transducer input slots available.
Field wiring cableaccessories allow theuser to conveniently connect both power and signals to the408DSPi. Theseaccessories support most voltageand constant current transducer applications without theneed for additional bulky equipment. Field wiring accessories and cables must beordered separately.
Networking Overview
The408DSPiis a securenetwork appliancethat supports DHCP or fixed IP addressing based on your network environment needs. When installed on a LAN/WANin DHCP mode, the DHCP server or router willassign an IP address to the408DSPi. When theuser makes a direct connection between the408DSPiand client computer in DHCP mode, an IP address willbe automatically assigned. The408DSPialso supports fixed IP addressing. Theuser can assign a fixed IP address on oneEthernet port whilesimultaneously running DHCP on the second Ethernet port. In someinstances, primarily when navigating corporatesecurity infrastructures, firewalls, or VPNs (VirtualPrivate Networks), specific router configuration may be necessary. Contact your localproduct support representativefor details specific to your needs.
