Seven. Usage and Maintenance Instructions

1. Installation and Power On

Power off installation, fixed in a single slot; the chassis is reliably grounded to prevent static electricity.

Power on preheating for 15 minutes, no hardware errors detected by NI MAX self-check.

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, tighten the BNC connection to reduce reflections.

Output short-circuit is prohibited; load matching (50/75 Ω), avoid overcurrent damage.

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

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

3. Calibration and Maintenance

Calibration Cycle: It is recommended to conduct NIST traceable calibration once every 2 years; use internal self-calibration to compensate for temperature drift on a daily basis.

Interface Maintenance: Clean the BNC interface regularly to keep it dry; add a dust cap for long-term inactivity.

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

Prohibited: Do not plug or unplug cables while powered on, do not subject to severe vibration, do not operate at excessive temperature.
