PCIe-6350 1.25 MS/s Multifunction DAQ Device
Земля NI PCIe-6350 provides 16 single-ended or eight differential analog inputs, 24 bidirectional digital I/O lines and four 32-bit counters for PCI Express measurement systems.
Its 16-bit ADC supports aggregate sampling at up to 1.25 MS/s. This makes it suitable for applications requiring faster acquisition than the 500 kS/s PCIe-6340 while retaining the same basic channel arrangement.

Single-ended wiring provides 16 channels, while differential wiring provides eight channels with better common-mode noise rejection.
Digital and Counter Functions
The board can monitor digital states, control fixture interfaces and perform encoder, frequency, period, PWM and event measurements.
PCIe-6350 Applications
- High-speed voltage acquisition
- Electronic functional testing
- Transient monitoring
- Machine monitoring
- Encoder measurements
- Production automation
Electronic Validation
The PCIe-6350 can capture faster-changing voltage signals and coordinate acquisition with external DUT triggers.
Machine Monitoring
Conditioned sensor voltages and counter-based speed signals can be acquired within synchronized NI-DAQmx tasks.
PCIe-6350 Installation Workflow
Step 1: Confirm PCI Express and NI-DAQmx Compatibility
Check the host computer and operating system.
Step 2: Select Shielded Connectivity

PCIe-6350 Troubleshooting
The board is not recognized
Check slot seating and NI-DAQmx support.
Measurements contain noise
Use differential wiring, shielding and suitable grounding.
Fast scanning produces settling errors
Reduce source impedance or add settling time.
Buffer overflow occurs
Optimize the acquisition loop and computer storage performance.
Digital control does not operate the load
Use a suitable external power driver.
