Description
NI PXIe-5105 | 60 MHz High-Density PXI Express Digitizer Card
Dynamic Product Introduction
Engineers running non-destructive testing (NDT) rigs or multi-receiver hydrophone arrays know how difficult it is to preserve phase alignment across high-channel-count acquisition stands. When a master digitizer drops channels or suffers ADC gain drift, swapping in a replacement card without disturbing calibrated signal routing or host software architectures becomes a top priority.
The NI PXIe-5105 houses 8 simultaneously sampled analog input channels within a single 1-slot PXI Express footprint. Engineered for high-throughput waveform streaming and low-noise acquisition, the PXIe-5105 features 12-bit ADC resolution and a 60 MHz analog bandwidth per channel. With onboard memory options up to 512 MB per channel, hardware-timed triggering, and PXI Express bus throughput for high-speed data streaming, the PXIe-5105 provides the channel density and phase-synchronization required for radar pulse analysis, medical ultrasound imaging, and multi-point vibration monitoring.

Global Sourcing & Live-Test SOP (Transparency Core)
Sourcing replacement high-speed digitizer cards requires rigorous functional validation to ensure sub-millivolt accuracy and channel-to-channel phase alignment.
Inbound Verification & Traceability
- Paperwork Audit: Validation of physical serial numbers against factory manufacturing databases to confirm hardware revision authenticity and calibration records.
- Physical Inspection: Comprehensive examination of all 8 SMB front-panel connectors, backplane PCIe edge contacts, shield grounding integrity, and thermal condition of onboard ADCs.
Live Rack Simulation & Diagnostics
- PXIe Backplane Verification: Board is loaded into an active PXI Express test chassis to verify PCIe device enumeration, DMA streaming, and NI-SCOPE driver handshake.
- Multi-Channel Digitizing Check: Connected to a calibrated function generator to sample continuous sine and square waves up to 60 MHz across all 8 channels simultaneously at 60 MS/s.
- Phase Alignment & Noise Floor Validation: Verifying channel-to-channel phase skew and verifying fast Fourier transform (FFT) signal-to-noise ratio (SNR) and total harmonic distortion (THD) parameters against published factory specs.
- 24-Hour Stress Run: Module undergoes a 24-hour thermal chamber burn-in running continuous waveform streaming under full sampling workloads to ensure thermal stability and zero packet loss.
Final Prep
- EEPROM Verification: Confirming onboard factory calibration constants and non-volatile EEPROM data integrity.
- ESD Safe Packaging: Sealed in anti-static shielding bags with desiccant packs before double-boxed air shipment.
The Field Engineer’s Pitfall Guide
- ❗ Impedance Mismatching (50 Ω vs. 1 MΩ): Operating the PXIe-5105 in 1 MΩ mode when driving high-frequency RF or fast pulses over 50 Ω coaxial cables will cause severe signal reflection and ringing. Always verify input impedance settings in NI-SCOPE before acquiring high-frequency data.
- ❗ Maximum Input Voltage Limits at 50 Ω: Applying signals greater than 5 Vrms while the channel input impedance is set to 50 Ω can trigger over-voltage protection or permanently damage the internal termination resistors. Always use external attenuators for high-voltage sources.
- ❗ Synchronization Across Multiple Cards: When slaving multiple PXIe-5105 cards together for 16-channel or 32-channel phase-coherent acquisition, failing to share the 100 MHz PXIe backplane reference clock (PXIe_CLK100) via NI-TClk software calls will result in sample clock drift between modules.
Intent-Driven FAQ
Will swapping out a damaged PXIe-5105 require updating my LabVIEW application?
No. Hardware replacement is completely transparent to your host software as long as the replacement module is installed in the same chassis slot and assigned the same alias within Measurement & Automation Explorer (MAX).
What driver software is required to operate the PXIe-5105?
The PXIe-5105 requires the NI-SCOPE instrument driver package. Ensure your host system is running an NI-SCOPE driver version that explicitly supports PXIe-5105 digitizer hardware.
Can all 8 channels on the PXIe-5105 acquire at 60 MS/s simultaneously?
Yes. The PXIe-5105 features an independent 12-bit ADC on every channel, allowing all 8 channels to sample at their full 60 MS/s rate simultaneously without multiplexing or throughput degradation.
Is the PXIe-5105 compatible with standard 32-bit PXI slots?
No. The PXIe-5105 uses a PXI Express peripheral connector and requires a PXI Express slot or a hybrid PXIe slot. It cannot be physically installed in legacy 32-bit PXI-only slots.
What warranty coverage comes with replacement modules?
All verified PXIe-5105 modules include a standard 12-month full-replacement warranty covering hardware functionality, channel sourcing accuracy, and sampling performance.
