Seoul National University JEOL JBX-8100FS DVIA-P4000 Installation Report

DVIA-ML1000 installation report — JEOL SEM model JSM-IT800 (serial 250801R2). Overview states the platform is appropriately installed and functioning as intended. Vibration-spec field form (Tuning Request) as screen capture, with N/A in the form text; Prepared for / End User / Location N/A. UI-program Autospectrum and Transmissibility (vertical, left-to-right, front-to-back) and equipment photo.

DVIA-ML1000 installation report (serial 240603R6) for ZEISS FIB-SEM Crossbeam 550 via YIMO. Overview matches the published form. Equipment condition: The equipment is turned on/IDLE. The source has no measurement summary table. Tuning Request field is blank (N/A). Published figures: vibration specification UI capture plus vertical, left-to-right, and front-to-back autospectrum and transmissibility from the UI program; decorative header raster omitted. Equipment picture is marked Photo Not Allowed in the handout (no equipment image published). Reference uses the standard Generic Vibration Criteria markdown table only (reference EMF not republished).

DVIA-MB1000 serial 160706R1 installation report for a ZEISS FE-SEM Sigma 300VP — tuning 2025-12-24, report written 2026-01-07 by Chaewon Lee (DAEIL SYSTEMS). Published plots follow DOCX §2a mapping: vibration specification capture under **Vibration Specification**, vertical / left-to-right / front-to-back transmissibility under **Data and Image**, then equipment photograph. Decorative letterhead raster after the website line (image1) is omitted; Reference uses the standard VC markdown table only (no Generic Vibration Criteria bitmap — image7.emf).

DVIA-MB1000 (serial 161213R2) tuning and vibration measurements for a TESCAN CLARA FE-SEM relocated to the Tier-1 Electronics Component Manufacturer Busan site A6 building 3F incoming inspection room. Tuning on 2026-01-06; report written 2026-01-07. The public page publishes nine measurement plots (VC curves, autospectra, transmissibility for vertical, left-to-right, and front-to-back). The decorative banner image above the title block and the Generic Vibration Criteria bitmap under 참고자료 are omitted in favor of the standard VC reference markdown table.
