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℃, avoid blocking the chassis fan.

2. Wiring and Operation

Use 50 Ω high-precision coaxial cable for signal output, tighten SMB connector to reduce reflection.

Output must not be short-circuited; the load must be matched (50/75 Ω) to prevent overcurrent damage.

Amplitude setting should not exceed 12 Vpp; high frequency (>1 MHz) prefer AC coupling.

Multi-card synchronization: share 10 MHz reference clock, enable NI-TClk, ensure phase coherence.

3. Calibration and Maintenance

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

Interface maintenance: regularly clean SMB interface, keep dry; add dust cover for long-term idle.

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

Prohibited: plug and unplug cables while powered on, severe vibration, overheating operation.
