LAN‑XI Light 3677 – Portable 4-channel Input + Generator Output DAQ Module

LAN‑XI Light 3677 is a rugged, stand‑alone 4‑channel input data acquisition module with an integrated signal generator output, built for precise sound and vibration measurement in both field and laboratory environments. Supporting CCLD transducers and 200 V microphones, it delivers professional‑grade performance as part of the flexible LAN‑XI modular DAQ system for multi‑channel measurements.

Powerful, portable and ready for real-world testing

3677 comes standard with the UA‑3100‑041 front panel (four BNC inputs + one BNC generator output), enabling full‑range excitation from 0 to 25.6 kHz – perfect for structural testing, modal analysis, acoustic diagnostics, and audio system evaluation. Optional UA-3102-041 front panel supports 200 V microphones, expanding its versatility across advanced measurement setups.

3677 becomes a portable, self‑contained recorder when paired with LAN-XI 2831 Battery Module and 3660-A WLAN Frame.

Using BK Connect®, engineers can control excitation waveforms including sine, stepped sine, random, burst, periodic, pseudo‑random, white noise, and user‑defined signals – making the 3677 an adaptable front end for countless test scenarios.

Key advantages

  • DC to 25.6 kHz input bandwidth with 65.5 kHz sampling for reliable NVH (noise, vibration and harshness), acoustic, and vibration measurements.
  • Integrated signal generator (0 to 25.6 kHz) for controlled excitation during structural and electroacoustic testing.
  • Supports CCLD transducers and TEDS auto‑configuration for fast, error‑free setup.
  • Rugged, field-ready design with color‑coded LED channel rings, LCD interface, and immediate access to overload/memory status.
  • Multiple power options: battery, PoE (power over Ethernet), DC, or mains – ideal for remote or mobile data acquisition.
  • Built‑in remote setup page, accessible via PC, tablet, or smartphone, enabling fast configuration anywhere.
  • Compatible with HBK software solutions PULSE™ LabShop and BK Connect®
  • LAN-XI Open API for custom or third‑party software integration.

Ideal applications

  • General sound and vibration recording and troubleshooting
  • Single-module, low-channel-count setups
  • Production‑line quality testing (pass/fail tolerance measurements)
  • Noise, vibration, and harshness (NVH) testing in harsh environments, including motorcycle or vehicle test tracks
  • Field‑based acoustic measurements such as traffic or environmental noise
  • Sound quality evaluations (loudness, sharpness, articulation index)
  • Structural testing using the integrated generator (modal analysis)
