PCI-6731

Part number(s):

778511-01

16-Bit, 4 Channels, 1 MS/s Analog Output Device

Overview

The PCI-6731 is a high-speed analog output device designed to deliver simultaneous, multichannel updates for control and waveform output applications such as stimulus-response tests, including acoustic distortion testing, and simulation such as three-phase power simulation. In addition, the device provides eight 5 V TTL/CMOS digital I/O lines; two 24-bit, 20 MHz counter/timers; and digital triggering and external clocking capabilities. The PCI-6731 can replace several kinds of instruments, including stand-alone proportional integral derivative (PID) controllers, low-speed arbitrary waveform generators, and function generators. You can control each data point for each channel to define common waveforms, such as square, sine, or sawtooth, as well as complex waveforms.

Product (Part Number) Description	Recommended use cases
FlexLogger Professional (785748-3501) FlexLogger Professional, Subscription License, Download	Recommended for automated, extensible data logging with NI data acquisition (DAQ) hardware. Automate tests using alarms, triggers, and events, and expand capabilities with plug-ins. Key Features Multichassis synchronization—Synchronize multiple NI chassis for accurate, time-aligned measurements across high channel counts. Logging triggers—Start, stop, or segment data recording automatically based on sensor thresholds or other conditions to capture only what matters. Events—Respond to specific occurrences during a test, such as activating equipment when a condition is met (for example, start cooling fans when temperature exceeds a limit). Automation APIs—Control and monitor FlexLogger from external applications (Python, NI LabVIEW, or NI TestStand), enabling integration into larger automated test systems. Calculation channels—Perform real-time math on acquired data (averages, RMS, custom formulas) to track derived measurements as the test runs. Plug-ins—Extend FlexLogger with custom LabVIEW or Python plug-ins to integrate third-party hardware, perform custom analysis, or connect to lab systems. CAN/LIN logging—Acquire and log automotive network data alongside sensor measurements for complete vehicle or subsystem testing.	View Product Details
LabVIEW+ Suite (788509-35) NI LabVIEW+ Suite, Subscription License, Download	Recommended for engineers building full test and validation systems where modular code development and higher-level frameworks are needed to accelerate development for shorter time to market. The LabVIEW+ Suite includes the following products: NI LabVIEW—Provides a graphical programming environment for test system development, enabling connectivity to any instrument and fully integrated user interfaces. NI TestStand—Eliminates the need for time-intensive in-house sequencer development and maintenance by providing an off-the-shelf test management software for validation and production test. NI DIAdem—Saves engineers hundreds of hours of manual data analysis and report creation with automation. NI FlexLogger™ software—Simplifies data acquisition and data logging with interactive measurement setup for NI DAQ hardware. NI InstrumentStudio™ software—Provides a central location for configuration, measurement, and automation.	View Product Details
