Seven. Usage and Maintenance Instructions Instruction Manual

Installation: Insert the PXIe chassis into any mixed slot while the power is off, and tighten the fixing screws; preferentially use shielded SMA/BNC cables (such as RG-223).

Wiring: RF signals use 50 Ω SMA, general signals use 1 MΩ BNC; external clock/trigger connect to the corresponding SMA port to ensure impedance matching.

Software configuration: Install the NI-SCOPE driver and PXI platform service, and identify the NI MAX module; set the sampling rate, bandwidth, impedance, trigger mode and memory depth; configure the clock source (internal/external) and synchronization routing.

Calibration: Preheat the system for 15 minutes upon startup; it is recommended to perform self-calibration and NIST traceability calibration once a year to ensure accuracy.

Maintenance instructions

Daily cleaning: Regularly wipe the front panel and connectors with a dry soft cloth to prevent dust from entering the interface; do not allow liquids to contact the module.

Connection check: Regularly check for looseness, oxidation or damage to the SMA/BNC connectors to prevent signal attenuation and impedance mismatch.

Environmental control: Working environment temperature 0–55°C, humidity < 90% without condensation, away from strong electromagnetic interference and vibration.

Fault troubleshooting: When there is signal abnormality, first check the cables and connectors; when synchronization fails, check the clock/trigger lines and backplane configuration; when data is lost, check the memory settings and bus bandwidth.

Long-term storage: Remove the module after power off, store it in a dry and cool environment to avoid static electricity and compression; storage temperature - 40–70°C.
