VII. Usage and Maintenance Instructions

1. Installation and Power On

Power off installation, single slot fixed; chassis reliable grounding to prevent static electricity.

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

Keep ventilation during operation, temperature ≤ 55℃, do not block the chassis fan.

2. Wiring and Operation

High-frequency signals use 50 Ω high-precision coaxial cables, BNC tightened to reduce reflection.

Output short-circuit prohibited; load no less than 50 Ω to avoid overcurrent damage.

Amplitude setting does not exceed ±5 V; for high-frequency (>1 MHz), AC coupling is preferred.

Multi-card synchronization: Enable NI-TClk, share 10 MHz reference clock to ensure phase consistency.

3. Calibration and Maintenance

Calibration cycle: Suggested 1-time NIST traceable calibration every 2 years; use internal self-calibration to compensate for temperature drift.

Interface maintenance: Regularly clean BNC interface, keep dry; add dust cap for long-term inactivity.

Environmental requirements: No condensation, humidity 10%–90% RH; away from strong electromagnetic interference and vibration.

Prohibited: Plug cables while powered on, severe vibration, overheating operation.
