Product Introduction
The National Instruments PXIe-4309 is a high-performance, precision analog input module engineered for advanced test, measurement, and data acquisition applications requiring exceptional dynamic range and measurement sensitivity. Featuring a flexible-resolution architecture, the module adapts dynamically to testing demands—scaling from 18 bits at a fast 2 MS/s per channel up to an ultra-high 28 bits at 2 S/s per channel.
Equipped with 32 differential input channels multiplexed across 8 synchronous sampling Analog-to-Digital Converters (ADCs), the PXIe-4309 incorporates advanced onboard capabilities including signal averaging, digital filtering, auto-zero measurement switching, and a chopper mode that utilizes channel pairs to deliver extreme noise rejection for precise, repeatable nanovolt-level measurements.

Compliance & Standards Alignment
- Designed in accordance with PXI Systems Alliance (PXISA) hardware specifications and relevant international EMC and safety standards (CE, FCC, and cULus compliant).
- Built for high-noise industrial test beds, laboratory automation, and precision sensor validation environments requiring robust electromagnetic compatibility (EMC).
Technical Note: Optimal performance and minimal signal settling time depend heavily on maintaining a low source impedance (\le 50\,\Omega in the DC to 2 MHz range) at the analog input terminals. Always use shielded cabling (such as SHC68-68-EPM) and proper terminal blocks (TB-4309) to preserve measurement integrity.
Storage & Asset Preservation Guidelines
- Store the module inside its original antistatic ESD shielding bag to protect sensitive analog front-end components and microprocessors from electrostatic discharge.
- Maintain a clean, climate-controlled storage environment with relative humidity maintained strictly below 60%.
- Avoid mechanical stress, bending, or dropping the module to prevent physical damage to the rear PXI Express backplane edge connector pins.
Physical Installation Prerequisites
- Ensure that the PXI Express chassis main power is completely turned off or placed in a safe standby state before inserting or removing any module.
- Slide the module gently along the chassis guide rails into an available PXI Express or hybrid slot, ensuring clean alignment before engaging the top and bottom retention thumbscrews.
- Connect the designated TB-4309 terminal accessory or shielded interface cable securely, verifying proper strain relief on field wiring.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this PXI data acquisition module?
A: Electronic measurement, test, and automated data acquisition modules generally classify under HS code 9030.89 (Instruments and apparatus for measuring or checking electrical quantities) or 8538.90. Confirm final parameters with your customs broker.
Q: Is the TB-4309 terminal block included with the PXIe-4309 module purchase?
A: Typically, terminal blocks (such as the screw terminal or VHDCI variants of the TB-4309) and specialized cables (like the SHC68-68-EPM) are sold separately unless specified in a bundled system kit. Verify package inclusions with your vendor prior to checkout.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, currency fluctuations, and factory calibration status; contact our technical sales desk for an official, time-sensitive formal quotation.
