Description
The PXI-6704 is a sophisticated PXI Analog Output module designed to cater to a variety of applications that require precise control and measurement. It features a robust part number system, with 185825A-01 being used in the market and 777796-01 designated by NI, ensuring users can identify and source the module efficiently.
This module boasts 16 voltage outputs and 16 current outputs, alongside 4 calibration channels, providing ample flexibility for numerous analog output tasks. The inclusion of 16-bit, time-division multiplexed DACs underscores the module’s capability to deliver high-resolution output signals, essential for precise control and measurement applications.
The analog output voltage range of -10.1 V to 10.1 V allows for a wide spectrum of signal generation, suitable for driving a diverse array of devices. Calibration channels are thoughtfully designed, with 2 for voltage (offset and gain) and 2 for current (offset and gain), facilitating accurate and reliable output performance.
Additionally, the module is equipped with 8 digital 5 V TTL/CMOS I/O lines, expanding its utility for mixed-signal applications. An onboard temperature sensor with a serial digital interface enhances the module’s adaptability to varying environmental conditions, ensuring stable operation.
The module’s commitment to precision is further evidenced by its continuous self-calibration feature, which actively compensates for any drifts in performance over time. It interfaces with the system through a 68-pin male connector, ensuring a secure and reliable connection.
Its physical dimensions are a compact 6.3 x 3.9 in., allowing it to fit comfortably in a variety of PXI chassis, making it an ideal choice for both portable and fixed installations. The calibration options available for this module include NIST accredited calibration (via 3rd party) and basic in-house calibration (unaccredited) prior to shipment, providing flexibility in meeting different
