Installation Report

Shanghai Silicon Power Semiconductor

PXB-BE-200HV

DVIA-ML1000

Overview

DSP board issue was identified; re-tuning after replacing the DSP board. Second tuning visit (first tuning 2025-01-13).

DVIA-ML1000 active isolation with PXB-BE-200HV — platform installed and functioning as intended; UI-program measurements while Turned on / IDLE in Shanghai.

The form lists N/A for Vibration specification; the measurement summary cites VC for floor vs DVIA-ML1000 at the reported dominant frequencies.

Generic VC / ISO reference levels are in Reference at the end.
