User and maintenance instructions

Installation and power-on

Power off for installation, single slot fixed; chassis reliably grounded to prevent static electricity NI.

Power on for 15 minutes for preheating, NI MAX self-check without hardware errors NI.

Keep ventilation during operation, temperature ≤ 55℃, do not block fans NI.

Connections and operations

High-frequency / RF signals use 50 Ω high-precision coaxial cables, BNC tightened to reduce reflection and loss NI.

Input prohibited > ±3 V (5 Vpp range), to avoid damaging the front end NI.

Trigger source preferentially selects signals within the channel, set appropriate trigger level to avoid false triggering; high-speed signals prefer edge triggering.

Multiple modules synchronize using PXI Star trigger to ensure ps-level phase consistency NI.

Maintenance and calibration

It is recommended to conduct NIST traceable calibration once every 2 years; daily internal self-calibration to compensate for temperature drift and time base errors.

Regularly clean BNC/SMB interfaces of dust, keep dry; for long-term idle, add a dust cap NI.

Environment free of condensation, humidity 10%–90% RH, away from strong electromagnetic interference and vibration NI.

Do not plug in or out cables while powered on; avoid severe vibration and impact NI.
