Eight Simultaneously Sampled Channels
The PXIe-5105 contains eight independent analog input channels that can acquire data simultaneously. Unlike multiplexed data acquisition devices, simultaneous sampling preserves the phase and timing relationships between channels.
This architecture is valuable for measuring multi-phase systems, power electronics, parallel sensor signals and other applications where timing differences between input channels must be analyzed accurately.
60 MS/s Sampling on Every Channel
Each PXIe-5105 channel can sample at up to 60 MS/s while all eight channels remain enabled. This provides a combined acquisition capacity of up to 480 million samples per second across the module.
The sample rate can be reduced for lower-frequency measurements and longer acquisition durations. An external sample clock from 4 MHz to 65 MHz can also be used when acquisition must follow a system-specific timing source.
12-Bit Vertical Resolution
The PXIe-5105 provides 12-bit vertical resolution, offering 4,096 quantization levels across the selected input range. This provides greater amplitude detail than conventional 8-bit oscilloscopes.
The additional resolution is useful for detecting smaller waveform changes, noise, ripple and distortion while maintaining the channel density required for automated test systems.
Flexible Input Ranges
The PXIe-5105 supports full-scale voltage ranges of 50 mVpp, 200 mVpp, 1 Vpp and 6 Vpp with either 50 Ω or 1 MΩ input impedance. A 30 Vpp range is additionally available with the 1 MΩ input configuration.
Selecting the smallest range that contains the complete waveform makes better use of the 12-bit ADC resolution. Higher-voltage signals may require an appropriate attenuating probe or external signal conditioning.
Selectable 50 Ω and 1 MΩ Inputs
Each channel supports programmable 50 Ω and 1 MΩ input impedance:
- 50 Ω input is appropriate for impedance-matched signal sources and coaxial signal paths.
- 1 MΩ input reduces loading on the circuit under test and provides access to the 30 Vpp input range.
Correct impedance selection helps maintain signal amplitude and reduce reflections. Verify the signal source impedance and cable configuration before starting an acquisition.
AC/DC Coupling and Anti-Alias Filtering
DC coupling preserves the complete waveform, including any DC offset. AC coupling removes the DC component and is available with the 1 MΩ input configuration.
A programmable 24 MHz anti-alias filter restricts the signal bandwidth and reduces high-frequency components that could alias into the measured frequency range. The filter can also improve noise performance when the full 60 MHz bandwidth is unnecessary.
Advanced Triggering Options
The PXIe-5105 supports several trigger configurations for repeatable waveform acquisition:
- Edge triggering
- Window triggering
- Hysteresis triggering
- Digital triggering
- Immediate triggering
- Software triggering
Any of the eight analog channels can be used as an analog trigger source. Digital triggers can be received through the front-panel PFI connection or PXI backplane trigger lines.
The PFI connection can also import an external sample clock or reference clock and export supported timing or acquisition events.
Deep Memory and Multi-Record Acquisition
The PXIe-5105 is available with 16 MB, 128 MB or 512 MB of onboard memory. Larger memory configurations support longer waveform captures and more multi-record acquisitions before data must be transferred to the controller.
Multi-record acquisition is useful for collecting many triggered events with reduced software overhead. Applications include pulse testing, repeated transient analysis and production systems that capture one waveform for each tested device.
PXI Timing and Synchronization
The PXIe-5105 supports internal, external and PXI-based clock sources. It can use the PXI backplane reference clock or a front-panel PFI reference clock to synchronize measurements with other instruments.
NI-TClk synchronization can align multiple supported PXI instruments. This allows engineers to expand the channel count using several modules or coordinate waveform acquisition with compatible signal generators and other modular instruments.
Typical PXIe-5105 Applications
- Multi-channel automated waveform acquisition
- Three-phase power electronics testing
- Automotive electronic system validation
- Production-line functional testing
- Semiconductor device characterization
- Parallel sensor signal measurement
- Transient and pulse analysis
- Embedded system validation
- Physics and scientific research
- Synchronized high-channel-count PXI systems
NI-SCOPE and InstrumentStudio Support
The PXIe-5105 uses the NI-SCOPE instrument driver. NI-SCOPE provides functions for configuring input channels, sampling, triggering, waveform transfer, measurements and calibration.
Supported programming environments include LabVIEW, LabWindows/CVI, Measurement Studio, C/C++ and .NET languages such as C# and VB.NET, subject to driver and operating-system compatibility.
InstrumentStudio provides an interactive interface for monitoring, controlling and recording measurements. NI Measurement & Automation Explorer can be used to identify the module, run self-tests and access device configuration tools.
PXI Express System Integration
The PXIe-5105 installs in a compatible PXI Express chassis and requires an embedded PXI controller or an externally connected computer. Confirm slot compatibility, controller bandwidth and chassis cooling before installation.
The module requires approximately 23 W of power. For specified measurement performance, allow at least 15 minutes of warm-up time and maintain proper forced-air cooling.
PXIe-5105 Troubleshooting
Why is the PXIe-5105 not detected?
Confirm that the module is installed in a compatible PXI Express slot. Install a supported NI-SCOPE driver, restart the system and check the device in NI Measurement & Automation Explorer.
Why does the measured amplitude appear incorrect?
Check the selected input impedance, voltage range and probe attenuation. A source designed for 50 Ω termination can produce an unexpected amplitude when connected to a 1 MΩ input.
Why does the waveform appear clipped?
Select a larger input range or use an appropriate attenuating probe. Verify that the signal remains within both the measurement range and maximum input overload specifications.
Why is AC coupling unavailable?
AC coupling is available only with the 1 MΩ input configuration. Change the channel impedance to 1 MΩ before selecting AC coupling.
How can waveform noise be reduced?
Enable the 24 MHz anti-alias filter when full bandwidth is unnecessary. Proper grounding, shielded cables, correct termination and waveform averaging can also reduce noise.
Why is the available record length lower than expected?
Onboard memory is shared among all enabled channels. Reducing the number of active channels, record length or number of records can increase the available acquisition capacity.
Why are channels not properly synchronized?
Confirm that all channels use the same sample clock and acquisition settings. For multi-module systems, configure the shared reference clock, triggers and NI-TClk synchronization correctly.
