National Instruments PXI-6040E

The National Instruments PXI-6040E (Part Numbers: 777484-01, 184361A-01) is a high-performance multifunction data acquisition (DAQ) device characterized by its exceptional 12-bit resolution and versatile capabilities. It offers 16 single-ended or 8 differential analog input channels, supporting a maximum sampling rate of 500 kS/s. This model integrates two analog outputs, making it an optimal choice for applications requiring high-speed data logging, high-voltage signal measurement, and various control applications. The PXI-6040E leverages a software-controlled single point input feature, allowing it to reach up to 50 kHz through NI-DAQ high-performance driver software, which effectively integrates with LabVIEW, LabWindows/CVI, and Measurement Studio.

The device provides 0.008 mV measurement sensitivity and features a 68-pin male 0.050 D-type I/O connector. It supports external digital or analog triggering at 10 kΩ impedance and offers an array of input modes, including not only differential and non-referenced single-ended but also referenced single-ended (RSE) suitable for floating signal sources. Users can efficiently scale voltage data into appropriate engineering units using measurement-ready virtual channels and can choose from pre-defined signals or create customized scales. The PXI-6040E also comprises an NI PGIA amplifier, ensuring fast settling times across various gains, which is crucial for high-gain measurements where standard commercial amplifiers may fall short.

The device has a recommended warm-up time of 15 minutes and should undergo annual calibration. It measures 6.3 x 3.9 inches and operates effectively within a temperature range of 0° to 55° C. Although the PXI-6040E has been designated as obsolete by National Instruments, it remains available for purchase and repairs through Apex Waves.
