Maximum X Series Channel Density
The PCIe-6357 is intended for systems that must acquire a very large number of analog voltage channels. The 1.25 MS/s capacity is shared among all channels included in the task.
Analog Generation
Two analog outputs provide synchronized stimulus generation, programmable DC levels and arbitrary waveforms.
Digital Control and Timing
Twenty-four digital lines and four counters provide fixture control, trigger routing, encoder input and pulse generation.
PCIe-6357 Applications
- High-density production testing
- Large sensor arrays
- Burn-in testing
- Reliability monitoring
- Automated electronic validation
- Stimulus-and-response testing
Large Production Fixtures
The board can consolidate hundreds of analog signals into one DAQ interface. Careful channel mapping and cable labeling reduce installation and maintenance errors.
Reliability Monitoring
Software can monitor many DUTs and apply alarm limits while recording long-duration results.
PCIe-6357 Installation Workflow
Step 1: Calculate Channel Throughput
Confirm that the aggregate rate meets the per-channel requirement.
Step 2: Design the Connection System
Plan every cable, connector group and terminal block.
Step 3: Install NI-DAQmx
Verify operating-system and development-environment compatibility.
Step 4: Install the Device
Power down the computer and follow ESD precautions.
Step 5: Validate Channels in Groups
Test each connector before assembling the complete fixture.
Step 6: Run the Complete Acquisition
Verify settling, crosstalk, throughput and buffer performance.
PCIe-6357 Troubleshooting
Some channels are not available
Check the extended connector and physical-channel names.
Channel-to-channel settling is poor
Reduce source impedance, slow scanning or add buffering.
The system cannot sustain the requested rate
Review the total channel count, computer performance and buffer configuration.
Analog output does not match the programmed signal
Check load impedance, voltage range, offset and cable condition.
Noise increases when digital signals switch
Separate analog and digital wiring and improve shielding.
