Seven, 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, SMB connector tightened to reduce reflection.

Short-circuit protection for output (no damage from long-term grounding), but it is recommended to match the load (50/75 Ω).

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

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

3. Calibration and maintenance

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

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

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

Prohibited: power-on unplugging cables, severe vibration, overheating operation.
