32-Channel Analog Acquisition
The PCIe-6259 provides 32 single-ended inputs for maximum density or 16 differential inputs for improved noise rejection. Seven input ranges support signals between ±100 mV and ±10 V.
Four Analog Outputs
Four analog outputs can generate stimulus voltages, reference levels and control signals. Output update capability depends on the number of channels used simultaneously.
External amplification is required for loads that exceed the voltage or current capability of the onboard outputs.
Hardware-Timed Digital I/O
Thirty-two of the 48 digital lines support hardware-timed waveform acquisition and generation. This enables repeatable digital patterns without relying entirely on operating-system software timing.
Counter and Synchronization Functions
Two counters support encoder measurement, event counting, frequency measurement and pulse generation. RTSI and programmable trigger routing can synchronize the PCIe-6259 with other compatible PCI or PCI Express instruments.
PCIe-6259 Applications
- Automated stimulus-and-response testing
- Production functional test
- Multichannel voltage acquisition
- Analog control-signal generation
- Digital pattern testing
- Industrial monitoring
- Laboratory automation
- Encoder and pulse measurement
- Research and development
Automated Electronic Testing
The PCIe-6259 can apply analog stimulus, acquire multiple DUT outputs and control fixture signals. Its multifunction architecture reduces the need for separate DAQ and waveform-output boards.
Multichannel Control Development
Analog outputs can control external systems while analog inputs measure feedback. Appropriate application timing and independent safety protection are required for control applications.
PCIe-6259 Installation Workflow
Step 1: Verify the PCI Express Slot
Confirm that the computer provides a compatible PCIe x1, x4, x8 or x16 slot.
Step 2: Install NI-DAQmx
Verify the operating-system and NI-DAQmx compatibility before hardware installation.
Step 3: Install the PCIe Board
Power down the computer, observe ESD precautions and secure the board in the chassis.
Step 4: Connect Both VHDCI Interfaces
Install the required shielded cables and identify Connector 0 and Connector 1 wiring.
Step 5: Test the Device
Use NI MAX to run a self-test and verify representative AI, AO, DIO and counter channels.
Step 6: Validate Safe Output States
Confirm analog output startup conditions and fixture interlocks before connecting the DUT.
PCIe-6259 Troubleshooting
The device is not detected
Check PCI Express slot configuration, board seating, BIOS settings and NI-DAQmx installation.
An analog output is incorrect
Verify the channel name, output range, load impedance, grounding and waveform scaling.
Measurements show unexpected channel delay
The inputs use multiplexed sampling. Channels are acquired sequentially rather than simultaneously.
Connector 1 signals do not match accessory labels
Use the PCIe-6259 connector-specific pinout instead of relying only on the terminal accessory labels.
A digital waveform reports an underflow
Check the sample clock, buffer size, data-transfer rate and availability of system resources.

PCIe-6259 vs PCI-6259
The primary difference is the computer interface. The PCIe-6259 uses PCI Express, while the PCI-6259 uses conventional PCI. Software and I/O capabilities are similar, but physical slot compatibility must be verified.
PCIe-6259 vs PCIe-6353
The PCIe-6353 is a newer X Series alternative with an updated timing architecture. Migration requires verification of timing behavior, connector pinout, drivers and application code.
Why Choose the PCIe-6259?
The PCIe-6259 is suitable when a test system needs high-density analog input, four analog outputs, extensive digital I/O and PCI Express connectivity.
