Part Code Definition

PXI = PCI extensions for Instrumentation industrial measurement bus standard

1031 = 4-slot AC-powered low-noise compact chassis fixed model

Technical Specifications

Slot layout：1 system controller slot +3 peripheral PXI slots, total 4 slots; controller slot supports up to 4-width embedded controller card

Power supply：300W universal AC built-in PSU, input 100~240VAC 50/60Hz, full channel overcurrent protection

Single slot cooling：max 25W per slot, total chassis heat load controlled by intelligent fan

Fan & noise：auto/high two-speed temperature-controlled fan; auto mode ≤35~40dBA(@25℃ ambient, ISO7779), low noise for lab environment

Backplane resource：onboard low-jitter 10MHz PXI reference clock, full 8 PXI trigger lines among all slots, PXI star trigger compatible

Dimension：177(H)×257.1(W)×212.8(D)mm; net weight ~5kg

Ambient rating：0℃~+50℃ operating, -20℃~+70℃ storage, RH5%~95% non-condensing; HALT accelerated aging certified design

Interface & Communication Configuration

Rear panel：IEC-C13 AC power inlet, chassis power switch, cooling fan exhaust, equipment grounding terminal

Backplane bus：standard PXI parallel bus + CompactPCI compatible bus, plug-and-play for NI & third-party PXI/CPCI modules

Software driver：works with NI-DAQmx, LabVIEW, TestStand, NI-SWITCH; no extra driver needed for chassis hardware itself

Mount option：standard desktop foot pads + rear rack ear for 19-inch 4U cabinet installation

Core Functions

Mechanical carrier & unified power supply for PXI DAQ/switch/arbitrary waveform generator modules

Backplane integrated synchronous 10MHz reference clock + full trigger routing, multi-card synchronous sampling without external clock wiring

Temperature adaptive fan speed regulation, reduce ambient noise for acoustic-sensitive vibration/NVH measurement test

Mixed compatibility for PXI and CompactPCI industrial control modules, flexible system configuration

Built-in overvoltage/overcurrent power protection to prevent module burnout from grid surge fluctuation

Application Scenarios

Laboratory small-scale sensor data acquisition, desktop vibration/NVH noise testing, university teaching measurement platform, small batch product automated functional test, legacy PXI system spare chassis replacement, portable field measurement cabinet assembly

Operation & Maintenance Notes

Keep chassis side ventilation grille unblocked for intake airflow; install chassis at least 5cm clearance around cooling vents; power off before hot swapping PXI modules; regular dust cleaning for rear fan and internal filter net; avoid stacking heavy equipment above chassis top cover.
