User and maintenance instructions

Installation and power-on

Power off installation, insert single slot and fix; chassis reliable grounding for anti-static

Self-check in NI MAX after power-on, confirm no hardware errors

Keep the chassis ventilated during operation, ambient temperature ≤ 55℃, avoid blocking fans

Wiring and operation

Use 50 Ω coaxial cable for analog input, tighten SMB connector to reduce signal reflection

Select 50 Ω impedance for high-frequency signals, 1 MΩ for low-frequency/high-voltage signals

Use AC coupling for AC signals, DC/cyclic signals for DC/cyclic signals

 channel internal signals as trigger sources， set appropriate trigger level to avoid false triggering

Use PXI trigger bus or RTSI for multi-module synchronization to ensure phase consistency

Maintenance and calibration

It is recommended to conduct NIST traceable calibration once a year； use internal self-calibration to compensate for temperature drift on a daily basis

Regularly clean dust from SMB interface， keep dry； add dust cap for long-term idle equipment

The working environment should have no condensation， humidity 5%–95% RH， and be away from strong electromagnetic interference

Do not input >±40 V voltage； do not plug or unplug cables while powered on； avoid severe vibration
