Fast Multichannel Acquisition
The PCIe-6352 provides more than twice the aggregate acquisition rate of the PCIe-6342. The rate is shared across the scan list rather than provided independently on every channel.
48 Digital I/O Lines
The digital lines support extensive fixture control and status monitoring. External conditioning is required for industrial voltage levels and power loads.
Counter and Encoder Functions
Four counters support quadrature encoders, frequency, period, pulse width, PWM and event-counting operations.
PCIe-6352 Applications
- High-speed multichannel acquisition
- Automated electronic testing
- Test-fixture control
- Machine monitoring
- Encoder measurement
- Research and laboratory automation
Production Testing
The board can acquire DUT voltage signals while monitoring and controlling numerous digital fixture points.
Laboratory Automation
Flexible timing and triggers allow the PCIe-6352 to coordinate multiple acquisition and counter tasks from one computer.
PCIe-6352 Installation Workflow
Step 1: Verify PCI Express Compatibility
Confirm the slot and NI-DAQmx environment.
Step 2: Select Cables and Terminals
Choose shielded accessories appropriate for the channel count.
Step 3: Install the Board
Power down the computer and observe ESD precautions.
Step 4: Wire Signals
Select single-ended or differential topology.
Step 5: Test in NI MAX
Run self-test and validate analog and digital channels.
Step 6: Configure the Application
Set rate, range, clock, trigger and buffering.
PCIe-6352 Troubleshooting
Noise appears on the inputs
Improve shielding, grounding and differential wiring.
The application cannot maintain 1.25 MS/s
Check buffer handling, disk speed and host-computer performance.
Measurements do not settle
Reduce source impedance or slow the multiplexed scan.
Digital lines show incorrect levels
Verify 5 V logic compatibility and a common reference.
Counter inputs miss pulses
Check pulse width, threshold, grounding and edge quality.
