Kintex-7 160T FPGA Processing
The PXIe-7867 uses a Kintex-7 160T FPGA to execute custom timing, triggering, waveform generation, signal processing and control logic directly in hardware.
FPGA execution provides deterministic response times and supports parallel operations that are difficult to achieve with conventional software-timed data acquisition hardware.
512 MB Onboard DRAM
The module includes 512 MB of onboard DRAM for waveform storage, acquisition buffering and FPGA-based block processing. This memory is useful for storing complex output waveforms or buffering acquired data before transferring it to the host.
Onboard DRAM also supports applications requiring long waveform sequences, repeated signal generation or high-throughput data processing.
18 FPGA-Controlled Analog Outputs
The PXIe-7867 provides 18 analog output channels with 16-bit resolution and update rates up to 1 MS/s per channel. Each output is directly controlled by the FPGA for deterministic waveform generation.
The high analog output channel count makes the module particularly suitable for sensor simulation, actuator command generation and hardware-in-the-loop systems that must reproduce multiple signals simultaneously.
Simultaneous Analog Input Acquisition
The module provides eight 16-bit analog input channels with dedicated ADCs. Signals can be acquired simultaneously at rates up to 1 Мвыб/с на канал.
Dedicated converters support independent channel timing, individual triggers and multirate sampling without the channel-to-channel delay found in multiplexed acquisition systems.
Programmable Analog Input Ranges
The analog inputs support programmable ranges of ±1 V, ±2 V, ±5 V and ±10 V. Selecting the smallest suitable range can improve measurement resolution for lower-amplitude signals.
Appropriate grounding, shielding and input configuration should be used to maintain measurement accuracy in electrically noisy test environments.
48 Bidirectional Digital I/O Lines
The PXIe-7867 provides 48 bidirectional digital I/O lines using 3.3 V single-ended signaling. Individual lines can be configured for input, output, triggering, handshaking or custom protocol functions.
With a maximum digital clock rate of 80 MHz, the module can interface with high-speed digital devices and coordinate analog waveforms with external test equipment.
Independent Timing and Triggering
Analog inputs, analog outputs and digital I/O can use custom timing and triggering logic implemented directly in the FPGA. Different channel groups can operate at different rates while remaining deterministically synchronized.
This flexibility supports custom trigger qualification, event sequencing, waveform branching and low-latency closed-loop responses.
PXI Peer-to-Peer Streaming
The PXIe-7867 supports peer-to-peer streaming for direct data transfers between compatible PXI Express modules. This reduces the need to route every transfer through the host controller.
Peer-to-peer streaming can reduce latency and host processor load in systems combining RIO modules, digitizers, signal generators and other high-performance instruments.

Hardware-in-the-Loop Testing
The PXIe-7867 is particularly suited to HIL systems that require many synchronized analog stimulus channels. Its 18 analog outputs can simulate multiple sensors or command signals, while the analog inputs monitor device responses.
Digital I/O can be used for status signals, triggers and protocol communication, allowing multiple test functions to operate from the same FPGA.
LabVIEW FPGA Programming
The PXIe-7867 can be programmed using the LabVIEW FPGA Module and compatible NI-RIO software. Developers can create custom FPGA applications for waveform generation, acquisition, triggering, communication and control.
After compilation, the FPGA application runs directly on the module and provides deterministic execution independent of host operating-system timing.
Connectivity and Signal Wiring
The PXIe-7867 provides separate connector groups for multifunction analog I/O, reconfigurable digital I/O and additional analog outputs. Compatible shielded cables and connector blocks are available for the RMIO and RDIO connections.
The additional analog output connector may require a custom interface or test fixture. Verify all pin assignments and maximum signal ratings before connecting external equipment.
PXI Express System Integration
The PXIe-7867 requires a compatible PXI Express chassis and controller. Chassis selection should account for slot compatibility, cooling, backplane bandwidth, synchronization and the power requirements of all installed modules.

Troubleshooting the PXIe-7867
The module is not detected by the system
Confirm that the PXIe-7867 is installed in a compatible PXI Express slot. Check the PXI chassis controller, PXI Platform Services and NI-RIO driver installation.
The FPGA bitfile cannot be downloaded
Verify that the bitfile was compiled specifically for the PXIe-7867. Confirm that the installed LabVIEW FPGA and NI-RIO versions support the module.
An analog output does not generate the expected voltage
Check the FPGA output value, channel assignment, load impedance, connector pinout and analog ground connection. Confirm that the commanded voltage remains within the supported output range.
Analog measurements contain excessive noise
Review signal grounding, shielding, input range and cable routing. Keep low-level analog signals separated from power wiring and high-speed digital lines.
Digital signals are not recognized correctly
Confirm that the connected device uses compatible 3.3 V logic. Check the FPGA line direction, pin assignment and shared digital ground.
Data transfer performance is lower than expected
Review DMA FIFO settings, onboard DRAM buffering, host processing load and PXI Express bandwidth. Peer-to-peer streaming may improve performance with compatible modules.
