Description

The NI PXIe-1092 is a 10-slot 3U chassis based on the PXI Express (PXIe) architecture, fully compliant with the PXI-5 PXI Express hardware specification. It integrates a high-performance 9-slot PXI Express backplane, high-output power supply, and optimized structural design. The chassis is designed to provide the highest level of performance, thermal performance, and flexibility for a wide range of automated test and measurement applications.

The PXIe-1092, along with the 18-slot PXIe-1095, is categorized as "highest performance, latest generation, highest thermal capacity," making it NI's most technologically advanced PXI Express chassis product to date. Compared to the PXIe-1085 (18 slots, 38 W/s thermal capacity), which also falls into the 24 GB/s bandwidth category, the PXIe-1092's 82 W/s thermal capacity is a significant differentiating advantage—meaning that engineers can run higher-power instrument modules within a more compact 10-slot space without worrying about thermal bottlenecks.

The PXIe-1092's fully hybrid backplane design offers seven hybrid peripheral slots, each accepting either PXI Express modules or PXI hybrid compatible modules, enabling high flexibility in module placement. Additionally, one system timing slot supports high-precision clock and trigger signal allocation, and one peripheral expansion slot (slot 10) provides power and mechanical alignment for multi-slot-width modules.

Key Features of The NI PXIe-1092 3U 82W 10 Slot PXI Chassis

• High-Performance Instrument Support

The PXIe-1092 is deeply optimized for high-end instrument applications, and its performance characteristics cover three key dimensions: data throughput, clock accuracy, and thermal management. PCI Express Gen 3 x8 Backplane: Each PXI Express slot provides up to 8 GB/s (unidirectional) dedicated bandwidth, based on x8 Gen-3 PCI Express links, for a total system bandwidth of up to 24 GB/s. Two PCI Express segments cover slots 2–4 and slots 5–9 respectively, with controller links supporting Gen 3 x8 and Gen 3 x16 configurations. 

82 W/slot cooling: Each slot provides 82 W of cooling capacity at ambient temperatures of 0–40 °C, and still provides 58 W/slot cooling at 0–55 °C, far exceeding the minimum requirement of 30 W in the PXI Express specification. This allows high-power instruments such as high-speed digitizers, RF transceivers, and FPGA modules to operate at full capacity.

Low jitter reference clock: The built-in 10 MHz reference clock (PXICLK10) and **100 MHz differential reference clock** (PXIeCLK100) both offer ±25 ppm stability, providing a precise timing reference for all modules within the system.

Quiet operation: The sound pressure level is only 35.9 dBA at ambient temperatures of 0–30 °C. The PXIe-1092, along with the PXIe-1090 and PXIe-1095, is among NI's quietest chassis products (32–38 dBA range), suitable for laboratory and desktop environments.

Variable speed fan control: The variable speed fan controller automatically optimizes heat dissipation and acoustic emissions, reducing noise at low loads and improving heat dissipation performance at high loads.

• High Reliability

Modular Design: The modular design of the chassis ensures high maintainability and an extremely low mean time to repair (MTTR). The power supply can be replaced in under one minute without disassembling the chassis or disconnecting I/O connections.

Comprehensive protection mechanisms: All DC outputs have short-circuit and overload protection (automatic recovery); +12V, +5V, and +3.3V have overvoltage protection (clamped at 20%–30% above the nominal output voltage).

System monitoring: NI MAX software allows real-time monitoring of voltage rails, temperature, fan speed, and power supply temperature, facilitating troubleshooting and preventative maintenance.

• Multi-Chassis Support

System timing slot: Slot 6 is the system timing slot, supporting the insertion of PXI Express system timing modules, enabling tight synchronization between multiple chassis.

Switchless CLK10 Routing: The backplane supports CLK10 signal routing without the need for switch switching, simplifying clock distribution in multi-chassis systems.

• Scheduled and Synchronized Upgrades (Optional)

Model 786991-01 includes timed and synchronous upgrades, providing the following enhanced features:

Internal 10 MHz OCXO Reference: Improves the frequency accuracy of the CLK10 and CLK100 from ±25 ppm (VCXO) to ±80 ppb, several orders of magnitude more stable than ordinary crystal oscillators.

10 MHz REF IN/OUT SMA Connector: Supports external 10 MHz reference clock input (auto-locked loop) and output, enabling multi-chassis synchronization.

High-Density Trigger Ports: Equipped with two HDMI trigger ports at the rear, enabling PXI trigger bus routing between chassis via HDMI cables.

Remote Disable and Fault Monitoring: A 15-pin connector at the rear supports remote power control and chassis health monitoring.

Within NI's PXI Express chassis product lineup, the PXIe-1092 3U 82W 10 Slot PXI Chassis belongs to the "1090 Series," a new generation of high-performance chassis. Together with the PXIe-1090 (2-slot desktop) and PXIe-1095 (18-slot flagship), it forms a complete high-end product line. The core technical features of this series include: 

PCI Express Gen 3 x8 Backplane: Compared to the previous generation Gen 2 products (such as early versions of PXIe-1085), Gen 3 increases the bandwidth per lane from 500 MB/s to approximately 1 GB/s, achieving 8 GB/s unidirectional bandwidth for the x8 link.

82 W/s Cooling Capacity: A significant improvement over the previous generation's 38 W/s or 58 W/slot cooling capacity.

Optimized Acoustic Design: PWM fan control combined with precise cooling algorithms achieves low-noise operation at 35.9 dBA

The PXIe-1092's unique value in NI chassis selection lies in bridging the gap between 10-slot capacity and the highest performance levels. For users who need more than eight instrument slots but don't require a full-size 18-slot chassis, the PXIe-1092 offers top-tier performance with 24 GB/s bandwidth and 82 W/s thermal performance, while maintaining a smaller footprint and lower cost.

Functions of The NI PXIe-1092 3U 82W 10 Slot PXI Chassis

• Backplate Architecture and Slot Functionality

The 10 slots of PXIe-1092 are functionally divided as follows:

Hybrid Slot Flexibility: Each hybrid peripheral slot accepts the following types of modules:

• PXI Hybrid Compatible modules (via XJ4 connectors, replacing the traditional J2 connectors)
• 32-bit CompactPCI peripheral modules (via a 32-bit PCI bus on the backplane)

The hybrid slot provides full PXI Express functionality and 32-bit PXI functionality (except for PXI Local Bus), connecting only the left and right sides of PXI Local Bus 6.

• Timed and Synchronized Functions

The PXIe-1092 3U 82W 10 Slot PXI Chassis backplane integrates complete PXI Express timing and synchronization signals.

PXI_CLK10 (10 MHz System Reference Clock): Driven to each slot, independent buffer drive, source impedance matched backplane, inter-slot skew less than 250 ps. PXIe_CLK100 (100 MHz Differential System Clock): Driven to each peripheral slot. PXIe_SYNC100 (Synchronization Signal): Driven to each peripheral slot, ensuring the timing relationship between CLK10 and CLK100. PXI Trigger Bus: 8 TTL trigger lines (PXI_Trig0–7), supporting inter-slot trigger signal transmission. Differential Star Trigger (PXIe_DSTAR): 3 dedicated differential pairs from the system timing slot to each PXI Express hybrid peripheral slot. PXI Local Bus 6: Routing between all slots.

• Inter-Chassis Synchronization (Requires T&S Upgrade)

The PXIe-1092, equipped with timing and synchronization upgrades, supports multi-chassis cascading synchronization:

HDMI Trigger Ports: Two rear HDMI ports are used for PXI trigger signal routing between chassis; each trigger line is bidirectional. 10 MHz REF IN/OUT: The SMA connector supports external reference clock input (auto-locked loop) and internal reference clock output. Recommended Connection:​​​​​​​ Chassis 1 Port 1 → Chassis 2 Port 0 (daisy-chaining for expansion into more chassis). Dynamic Trigger Routing: Only supports dynamic routing via drivers such as NI-DAQmx; static routing in MAX is not supported

• Front Panel Functions

Power Switch: Controls the internal power supply to the PXI Express backplane. Power Indicator LED: Indicates the chassis power supply status. Fan Indicator LED: Indicates fan operating status. Temperature Indicator LED: Indicates over-temperature alarm. Peripheral Expansion Slot (Slot 10): Clearly labeled, for power supply expansion only.
