1 GHz Analog Bandwidth
The PXI-5154 provides 1 GHz analog bandwidth on both input channels. This makes it suitable for measuring fast digital edges, high-frequency clock signals, pulse waveforms, communication signals and broadband electronic events.
Available measurement bandwidth depends on the complete signal path, including probes, coaxial cables, adapters, fixtures and source termination. Use high-quality 50 Ω cabling and impedance-controlled connections to preserve the module’s frequency response.
2 GS/s Single-Channel Sampling
The PXI-5154 provides a maximum real-time sampling rate of 2 GS/s when operating with one analog input channel. This mode supports detailed acquisition of high-speed transient and single-shot signals without relying on repetitive waveform reconstruction.
A 2 GS/s sample rate corresponds to a sampling interval of 500 ps. The actual temporal detail available in a measurement also depends on analog bandwidth, trigger stability, signal-to-noise ratio and waveform interpolation.
Simultaneous Dual-Channel Acquisition
When both analog channels are enabled, the PXI-5154 supports simultaneous sampling at up to 1 GS/s per channel. This allows engineers to compare two related signals, such as input and output waveforms, clock and data signals or stimulus and response.
Because both channels share a common acquisition timing system, waveform timing can be compared without the uncertainty associated with separate standalone oscilloscopes.
Random-Interleaved Sampling
For repetitive signals, the PXI-5154 supports random-interleaved sampling at effective rates up to 20 GS/s. This mode combines samples from multiple repeated acquisitions to create a waveform with finer time spacing.
Random-interleaved sampling is not appropriate for nonrepetitive or single-shot events because it requires a stable waveform that repeats relative to the trigger. Real-time sampling should be used when every acquisition may contain unique information.
8-Bit Vertical Resolution
The PXI-5154 uses an 8-bit analog-to-digital converter. This resolution is optimized for high-speed waveform capture where sample rate and bandwidth are more important than precision DC measurement.
Selecting the smallest suitable input range improves utilization of the converter’s available codes. Excessively large ranges reduce voltage resolution, while ranges that are too small can clip or overload the acquired waveform.
Programmable Input Ranges
The oscilloscope provides full-scale input ranges of 100 mVpk-pk, 200 mVpk-pk, 500 mVpk-pk, 1 Vpk-pk, 2 Vpk-pk and 5 Vpk-pk. These ranges allow the acquisition system to be adapted to signals with different amplitudes.
Always account for the signal’s DC offset and transient peaks when selecting a range. The complete waveform must remain inside the configured acquisition window to avoid clipping.
50 Ω Input Termination
The PXI-5154 analog inputs use fixed 50 Ω termination. This impedance is appropriate for RF, communications and high-speed digital systems constructed with 50 Ω sources, cables and fixtures.
The module does not provide the 1 MΩ input commonly found on general-purpose benchtop oscilloscopes. A suitable high-impedance probe, active probe interface or external adapter is required when the circuit cannot safely drive a 50 Ω load.
AC, DC and Ground Coupling
DC coupling passes both the DC component and time-varying content of the input signal. AC coupling removes much of the DC component, helping users examine a smaller varying waveform superimposed on a larger offset.
Ground coupling disconnects the external signal from the acquisition path and connects the internal path to ground. It can be used to evaluate the oscilloscope baseline and offset condition.
Deep Onboard Acquisition Memory
Depending on the ordered configuration, the PXI-5154 includes 8 MB, 64 MB or 256 MB of onboard memory per channel. Deep memory allows longer time windows to be recorded while maintaining a high sampling rate.
Additional memory is particularly useful for protocol analysis, radar pulse capture, transient monitoring and applications where an event occurs long after acquisition begins.
Multirecord Acquisition
Multirecord acquisition divides onboard memory into separate waveform records. The PXI-5154 can capture many triggered events without transferring every waveform to the host controller immediately after acquisition.
The 8 MB configuration supports as many as 32,768 records, while the 64 MB and 256 MB configurations support as many as 100,000 records. The practical record count depends on record length, reference position and acquisition settings.
Advanced Triggering
The PXI-5154 supports analog edge triggering from its input channels as well as digital and software trigger sources. Trigger configuration can include source, level, slope, coupling, delay and reference position.
PXI trigger lines allow an acquisition to be initiated by another instrument, a PXI controller or a test-system event. The module can also participate in synchronized measurement sequences involving signal generators and additional digitizers.
PXI and NI-TClk Synchronization
PXI timing resources and NI-TClk technology allow the PXI-5154 to be synchronized with compatible modular instruments. Multiple digitizers can acquire additional channels, or a waveform generator can produce a stimulus aligned with the oscilloscope acquisition.
Synchronization accuracy depends on chassis timing architecture, cabling, reference-clock configuration and the capabilities of every participating module. NI-TClk synchronization should be configured through supported NI instrument drivers.
Self-Calibration and External Calibration
Self-calibration adjusts internal gain, offset, timing and trigger parameters to compensate for changes in operating temperature. Perform self-calibration after the module has warmed up and whenever the chassis temperature changes significantly.
The recommended warm-up period is 15 minutes, and the specified external calibration interval is two years. Measurement programs that require traceable results should follow the applicable calibration schedule.
NI-SCOPE Software Support
The PXI-5154 is controlled with the NI-SCOPE instrument driver. NI-SCOPE provides functions for configuring channels, sample rates, record lengths, triggers, multirecord acquisition and waveform transfer.
The driver can be used with LabVIEW, LabWindows/CVI, C, C++, .NET and other supported development environments. Soft Front Panel software can also be used for interactive configuration and initial signal inspection.

High-Speed Digital Signal Testing
The 1 GHz bandwidth and 2 GS/s single-channel rate allow the PXI-5154 to capture clock signals, pulse trains and other fast digital waveforms. Measurements can be used to evaluate amplitude, frequency, overshoot, undershoot and timing behavior.
For reliable results, use controlled-impedance fixtures and minimize cable length, connector transitions and unterminated branches. Signal-integrity problems in the fixture can otherwise appear as device-under-test behavior.
Communication and Modulated-Signal Analysis
The PXI-5154 can acquire intermediate-frequency and other broadband communication signals for time-domain or software-based spectral analysis. Captured data can be processed using custom algorithms or compatible NI analysis software.
Its 8-bit resolution should be considered when the application requires a large dynamic range or the detection of very small signals near larger spectral components.
Pulse and Transient Capture
Deep memory and multirecord acquisition make the PXI-5154 useful for observing short-duration pulses and intermittent transient events. A series of triggered pulses can be stored onboard and transferred as a group for analysis.
This approach can improve test throughput by reducing communication overhead between individual acquisitions.
Semiconductor and Component Validation
The PXI-5154 can measure high-speed responses from amplifiers, converters, clock devices, interfaces and other electronic components. When combined with PXI waveform generators, digital instruments and source-measure units, it can form part of an automated characterization system.
Fixture loss and frequency-dependent response should be characterized when testing devices near the upper end of the module’s analog bandwidth.
Production Test Integration
The PXI form factor allows the oscilloscope to operate in a compact automated test platform alongside switches, digital instruments, waveform generators and programmable power supplies.
Programmatic control enables consistent configuration, acquisition and analysis across repeated production tests. Stored calibration information and self-calibration support measurement stability during extended operation.
PXI-5154 Troubleshooting
The PXI-5154 Is Not Detected in NI MAX
Confirm that the module is fully installed in a compatible PXI or PXI hybrid slot. Check chassis power, controller communication and the installed NI-SCOPE version, then rescan the system in NI Measurement & Automation Explorer.
The Input Signal Amplitude Is Too Low
Verify that the source is designed to drive a 50 Ω load. A source specified for a high-impedance load may produce approximately half its open-circuit voltage when connected to the PXI-5154 input.
The Waveform Is Clipped
Select a larger voltage range or adjust the vertical offset. Confirm that both the signal amplitude and DC offset remain within the configured input range and the module’s absolute overload limits.
The Signal Shows Excessive Ringing
Check for impedance mismatches, unterminated cables, adapters, long fixture traces and connector discontinuities. Use 50 Ω cables and terminate every high-speed signal path correctly.
The Selected Sample Rate Is Unavailable
The 2 GS/s real-time rate is available in single-channel operation. When both analog channels are enabled, the maximum real-time sampling rate is 1 GS/s per channel.
Random-Interleaved Sampling Produces Poor Results
Confirm that the waveform is repetitive and stable relative to the trigger. Use real-time sampling for single-shot, changing or asynchronously timed signals.
Triggered Events Are Being Missed
Review the trigger source, level, slope, coupling and holdoff. For events that occur in rapid bursts, use multirecord acquisition to reduce the time required for waveform transfer between triggers.
The Baseline or Gain Changes with Temperature
Allow the module to warm up for at least 15 minutes and perform self-calibration. Verify chassis airflow and repeat self-calibration if the operating temperature changes significantly.
Two Instruments Are Not Properly Synchronized
Verify that the modules share the intended reference clock and trigger resources. Configure compatible devices through NI-TClk and confirm that every instrument supports the selected synchronization arrangement.
