User and maintenance instructions

Installation and power-on

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

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

Keep the chassis ventilated during operation, with the environmental temperature ≤ 55°C, and avoid blocking the fan.

Wiring and operation

Use 50 Ω coaxial cables for high-frequency/high-speed signals, tighten the BNC connector to reduce signal reflection and loss.

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

Use AC coupling for AC small signals, DC coupling for DC/low-voltage signals.

Prioritize using signals within the channel as trigger sources, set appropriate trigger levels to avoid false triggering; use edge triggering for high-speed signals.

Use PXI Star triggering for synchronous use of multiple modules to ensure ps-level 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 and time base errors in daily use.

Regularly clean dust from BNC/SMB 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 and vibration.

Do not input >±6 V voltage; do not plug or unplug cables while powered on; avoid severe vibration and impact.
