Product Overview
The National Instruments PXI-6713 is an analog output module for PXI systems. It provides eight analog output channels with 12 bit resolution and a maximum update rate of 1 MS/s. The module also includes digital input and output lines for control and handshaking. It is designed for waveform generation, stimulus response testing, and control applications that require multiple analog outputs.
The PXI-6713 is part of the NI analog output product family. It is used in test systems where multiple actuators, drivers, or signal inputs must be controlled from one PXI slot. Because it is a PXI module, it can be synchronized with analog input, switching, and measurement instruments in the same chassis.
Analog Output Performance
The module provides eight independent analog output channels with 12 bit resolution. Output ranges are selectable to match the requirements of the driven device. Hardware timed generation allows the module to produce deterministic waveforms, ramps, and patterns across all channels. Engineers should confirm the load and settling requirements for the connected equipment.
Simultaneous or coordinated updates across channels help maintain phase relationships between output signals. This is useful in multi axis control, quadrature signal generation, and multi channel stimulus applications. The update rate of up to 1 MS/s supports waveform generation at frequencies well above the range of mechanical actuators, which allows smooth command profiles.
Digital I/O and Triggering
The PXI-6713 includes digital input and output lines that can be used for handshaking, relay control, and status monitoring. Trigger inputs allow waveform generation to start or stop on an external event. The module can also generate trigger signals for other instruments, which helps coordinate a sequence of measurements and stimuli.
NI-DAQmx exposes trigger and clock configuration so that output timing can be aligned with analog input or with external equipment. Engineers should document the trigger routing and clock source so that the test sequence can be reproduced. Careful timing design reduces uncertainty when correlating output commands with measured responses.
Signal Quality and Wiring
Analog output signal quality depends on cabling, grounding, and the load connected to each channel. Shielded cable and separation from power wiring help reduce noise coupling. Engineers should verify output behavior with an oscilloscope or digitizer before connecting sensitive devices, especially when long cables or high capacitance loads are involved.
Each output channel should be protected against short circuits and overvoltage within the module specifications. External protection may be needed for inductive loads or equipment that can feed voltage back into the output. These precautions help avoid damage and maintain measurement confidence.
Software and PXI Integration
The PXI-6713 is supported by NI-DAQmx and can be programmed with LabVIEW, LabWindows/CVI, Measurement Studio, and other NI-DAQmx compatible environments. The driver provides channel configuration, output range selection, timing, and trigger setup. Engineers can build waveform generation tasks that run deterministically within the PXI chassis.
Within a PXI system, the module can be combined with analog input, DMMs, switches, and signal conditioners. This allows a test to generate a stimulus, route it through a switch, measure the response, and evaluate results in one application. The PXI platform provides a common timing and software environment for these instruments.
Typical Applications
