User and Maintenance Instructions

Installation and Power On

Power off installation, insert into single slot and fix; the chassis is reliably grounded to prevent static electricity.

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

Keep the chassis ventilated during operation, environmental temperature ≤ 55℃, avoid blocking the fan.

Wiring and Operation

Use 50 Ω coaxial cable for high-frequency signals, tighten the BNC connector to reduce signal reflection NI.

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

Use AC coupling for AC small signals, DC / slow-changing signals use DC coupling NI.

Prioritize selecting signals within the channel as trigger sources, set appropriate trigger levels to avoid false triggering.

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

Maintenance and Calibration

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

Regularly clean dust from BNC/SMB/DIN interfaces to keep them dry; add a dust cap when the equipment is idle for a long time.

The working environment should be free of condensation, with a humidity of 10%–90% RH, and away from strong electromagnetic interference.

Do not input >±20 V voltage; do not plug in or unplug cables while powered on; avoid severe vibrations.
