# Astro-Med TMX-18 High-Speed Data Acquisition System (Pre-Owned) # Astro-Med TMX-18 High-Speed Data Acquisition System (Pre-Owned) ## Key Features At A Glance - 18 channels of voltage and DC bridge inputs across three UNIV-6 universal isolated voltage modules - Sample rates up to 800 kHz per channel with bandwidth up to 100 kHz - 17-inch high-resolution touch screen display (1280 x 1024) with full-screen resistive touch - Dedicated 1 TByte removable SATA hard drive for data capture, separate from system storage - Each channel uses a separate 16-bit A/D with BackChannel technology for synchronized capture - MIL-STD-810F tested for shock (Method 516.5, Procedure I) and vibration (Method 514.5, Procedure I) - Eight USB 2.0 ports, 1000BaseT Ethernet, and VGA out for external monitor support - 250 Vrms isolation (Cat II) on input modules with selectable ranges from 200 mV to 800 V full scale The Astro-Med TMX-18 is a portable high-speed data acquisition system that combines 18 channels of isolated voltage and DC bridge inputs with a 17-inch touch-screen display in a single ruggedized chassis. The base configuration uses three UNIV-6 Universal Isolated Voltage Modules, each providing six channels with 250 Vrms (Cat II) isolation, AC/DC coupling, and selectable input ranges from 200 mV full scale through 800 V full scale. Sample rates reach 800 kHz per channel with bandwidth up to 100 kHz, and each channel uses a separate 16-bit A/D converter so that multi-channel data remains time-aligned at acquisition. The system is designed for field and lab applications where long-duration trending must be combined with the ability to capture transient events without missing detail. Listed use cases include long-term trending and high-speed event detection, transient capture, timing and synchronization analysis, power monitoring (using the DSP RMS filter), and acceleration/deceleration measurement applications (using the integration and differentiation filter functions). The 18-channel chassis accepts up to three analog input modules and provides 16 TTL event inputs along with derived-channel math functions including sum, difference, product, quotient, exponential, sine, cosine, tangent, inverse trig, exponential square root, and absolute value. Whether you are integrating a TMX-18 into a flight test instrumentation rack, a production-floor monitoring station, or a long-duration vibration survey, ValueTronics stocks, tests, and ships data acquisition systems from our 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Our in-house technical team verifies functionality before each unit ships, which matters for multi-module DAQ systems where channel count, input module configuration, and optional capabilities such as IRIG/GPS or CAN bus must be confirmed against the customer's measurement requirement before delivery rather than after. ## Brand Heritage Astro-Med, Inc. operates the Test & Measurement Product Group that manufactures the TMX series along with the company's other recording and data acquisition product lines. The corporate parent, headquartered in West Warwick, Rhode Island, has since rebranded as AstroNova, Inc.; both names refer to the same continuing operation and the TMX product line transitioned with the rebrand. ## Accessories Supplied - AstroVIEW X PC-based data review and analysis software - TMX-18 Offline software ## Product Core & Specifications 18-Channel Chassis with 3 UNIV-6 Universal Isolated Voltage Modules Maximum Analog Modules 3 Maximum Analog Waveforms 18 Event Inputs (TTL) 16 Derived Channels +, -, x, ÷, Exponential, Sin, Cos, Tan, Asin, Acos, Atan, Exp √, Absolute Value Data Acquisition Recording Operational Modes Scope, Review, Real-time (strip-chart) Recording Method Internal removable 1 TByte SATA disk drive Time Stamp Time and date automatically saved with data Trigger Point Amount of pre and post trigger is user adjustable Filtering Low pass, high pass, band pass, band stop, RMS, integration & differentiation Color Display Type Active matrix color LCD (TFT) Viewing Area 17 in.

Confirm the intended chassis configuration before specifying sample rate requirements.**Important:** CAN bus and MIL-1553 input options are listed in the datasheet as optional bus input capabilities; the standard TMX-18 chassis does not include these inputs.Recommended pairing: when synchronized video documentation of the device under test is required alongside the analog data, specify the TMX-VA Video/Audio Acquisition option or the TMX-HSV High Speed Video option per the datasheet's TMX Options section. ## About this used unit - Warranty included - Functional verification included - Standard Calibration Upgrade Options: No Calibration Required, NIST Traceable, Z540.1 or ISO 17025 with Data, Z540.3 Guardbanding with Data. - Note that unnecessary accessories may not be included (contact Test Architect to confirm). **Please review the Manufacturer's Data Sheet to verify published specifications.
