The three PXI-5152 versions provide the same principal channel count, sampling rate, resolution and bandwidth. Their primary difference is the amount of onboard acquisition memory installed for each channel.
Dual 1 GS/s Simultaneous Inputs
With both channels enabled, each input samples at up to 1 GS/s. The simultaneous architecture preserves phase and timing relationships between the two measured signals.
This is useful for comparing device input and output signals, measuring propagation delay, analyzing differential timing and capturing related transient events.
2 GS/s Single-Channel Sampling
When only one channel is required, the PXI-5152 combines its ADC resources in time-interleaved sampling mode to provide a real-time rate of 2 GS/s.
TIS mode is appropriate for nonrepetitive high-speed events because it captures the waveform in a single occurrence. Confirm the selected channel and mode in NI-SCOPE before configuring a 2 GS/s acquisition.
20 GS/s Random-Interleaved Sampling
For stable repetitive signals, random-interleaved sampling provides effective sample rates from 2 GS/s to 20 GS/s. The module combines samples from repeated waveform cycles to create finer time spacing.
RIS should not be used for single-shot, modulated or changing events because it assumes that successive waveform repetitions are substantially identical.
300 MHz Analog Bandwidth
The PXI-5152 provides at least 300 MHz bandwidth on most input ranges, with higher typical bandwidth on the 50 Ω signal path. This supports high-speed digital signals, communications waveforms, pulses and fast electronic transients.
The smallest 100 mVpp range has reduced bandwidth. Check the range-specific specification when both maximum sensitivity and maximum frequency response are required.
8-Bit Vertical Resolution
The ADC provides 256 theoretical amplitude levels across the selected range. Its architecture prioritizes high-speed waveform capture and precise timing rather than very-high-resolution DC measurement.
Selecting the smallest range that safely contains the waveform improves amplitude sensitivity. Allow margin for noise, DC offset, overshoot and ringing.
Input Ranges from 100 mVpp to 10 Vpp
The PXI-5152 offers seven ranges from 100 mVpp to 10 Vpp. Each channel can be configured independently according to its signal amplitude.
Programmable offset allows a smaller input range to be positioned around a nonzero voltage, improving the visibility of ripple or transient behavior on a DC level.
50 Ω Input Impedance
The 50 Ω path is optimized for impedance-matched signal generators, RF-style sources and high-speed coaxial measurement systems. Matching the source, cable and digitizer reduces reflections.
Observe the lower overload limits of the terminated input. Excessive voltage can activate protection or permanently damage the internal termination.
1 MΩ Input Impedance
The 1 MΩ path reduces loading on high-impedance circuits and supports conventional passive oscilloscope probes. Its approximately 22 pF input capacitance affects loading at higher frequencies.
Use a compensated probe with a short ground connection to minimize ringing, pickup and distortion.
AC, DC and Ground Coupling
DC coupling preserves the complete waveform, including its DC level. AC coupling blocks the DC component and helps measure ripple or noise on top of a larger DC voltage.
The low-frequency cutoff is approximately 12 Hz in 1 MΩ mode and significantly higher in 50 Ω mode. Ground coupling provides an internal baseline reference.
20 MHz Noise Filter
A software-selectable 20 MHz bandwidth filter reduces broadband noise when high-frequency content is not required. It can improve effective resolution and measurement stability for lower-frequency signals.
Disable the filter when capturing fast edges or signal components above 20 MHz.
Deep Onboard Memory
The PXI-5152 is available with 8 MB, 64 MB or 256 MB of memory per channel. Deep memory permits longer waveform records at high sampling rates.
In 2 GS/s single-channel TIS mode, the memory is used by the active channel. In conventional real-time or RIS operation, memory is available independently to the enabled channels.
Multiple-Record Acquisition
Multiple-record mode captures separate waveform segments associated with individual trigger events. Hardware rearming prepares the digitizer rapidly for each subsequent event.
The 64 MB and 256 MB configurations can store up to 100,000 records under supported record-length conditions.
Pretrigger and Post-Trigger Acquisition
Pretrigger data shows signal behavior before the trigger condition, while post-trigger samples capture what happens afterward. The trigger can be positioned anywhere within the supported record.
This is useful for diagnosing intermittent faults and identifying events that occurred immediately before a threshold crossing or failure.
Advanced Analog Triggering
Edge triggering starts an acquisition when a signal crosses a selected voltage level. Window triggering detects when a signal enters or exits a defined band, while hysteresis improves stability for noisy transitions.
The external trigger input provides AC or DC coupling and a high-impedance connection for external trigger signals.
Digital Triggering and PFI
Digital trigger sources include PXI trigger lines, the PXI Star Trigger and front-panel PFI connections. The two PFI connectors can be configured for trigger input, event output and other timing functions.
PFI outputs can indicate the start or end of an acquisition, end of a record or another supported instrument event.
Low Trigger Jitter
Typical trigger jitter is approximately 10 ps RMS, with a specified maximum of 20 ps RMS under supported conditions. Low jitter improves the repeatability of high-speed edge and timing measurements.
Total system timing uncertainty also includes sample-clock jitter, signal noise, trigger slew rate and synchronization error.
PXI and NI-TClk Synchronization
The PXI-5152 can use PXI trigger lines, the Star Trigger and the PXI reference clock for coordination with other modules. NI-TClk technology aligns compatible instruments for phase-coherent acquisition.
Multiple PXI-5152 modules can be combined to create higher-channel-count systems while maintaining subnanosecond timing relationships.
Built-In Self-Calibration
Software-controlled self-calibration compensates for gain, offset, triggering and timing errors at the current operating temperature. A 15-minute warm-up period is recommended.
External calibration adjusts the internal timing and voltage references. NI recommends a two-year external calibration interval.
Communications Testing
The 300 MHz bandwidth and 50 Ω input path support baseband, intermediate-frequency and communications waveform acquisition. Software can calculate spectral content, power, timing and modulation-related parameters.
For measurements requiring higher dynamic range or onboard digital downconversion, consider a dedicated communications digitizer such as the PXI-5142 or PXIe-5622.
High-Speed Digital Testing
The PXI-5152 can capture clock signals, pulse trains and other digital waveforms for rise-time, fall-time, overshoot, ringing and propagation-delay analysis.
Use controlled-impedance connections and appropriate probes because the measurement fixture can significantly affect fast signal edges.
Radar and Pulsed-Signal Acquisition
Deep memory, multiple-record acquisition and rapid trigger rearming make the PXI-5152 useful for capturing radar, sonar and other pulsed events.
Instead of storing inactive time between pulses, multiple-record mode retains only the waveform region surrounding each trigger.
Power Electronics Testing
The module can acquire gate-drive, control, isolated voltage-probe and current-sensor signals from converters, inverters and motor-control systems.
Because the inputs are referenced to chassis ground, appropriate differential probes or isolated transducers are required for floating or high-voltage measurements.
Scientific and Research Measurements
The PXI-5152 can acquire detector outputs, optical pulses, ultrasonic waveforms and other fast experimental signals. Its deep memory supports long records or large numbers of events.
External timing inputs can synchronize the acquisition with a laser, pulser, mechanical system or other experimental hardware.
Automated Production Testing
NI-SCOPE enables software-defined waveform measurements for production systems. Test programs can calculate amplitude, frequency, rise time, pulse width and other parameters automatically.
PXI synchronization coordinates the digitizer with signal generators, switches and digital instruments to improve throughput and repeatability.
NI-SCOPE Software Support
The PXI-5152 is controlled through the IVI-compliant NI-SCOPE driver. NI-SCOPE provides functions for configuring ranges, coupling, impedance, sampling, triggering, memory and synchronization.
The driver supports LabVIEW, LabWindows/CVI, Measurement Studio and compatible C, C++ and .NET environments. The NI-SCOPE soft front panel provides interactive control and waveform display.

PXI-5152 Troubleshooting
The PXI-5152 is not detected in NI MAX
Confirm that the module is fully installed in a compatible PXI or PXI Express hybrid slot. Check chassis power, controller communication and NI-SCOPE installation, then restart NI Measurement & Automation Explorer.
The maximum rate is only 1 GS/s
With both channels enabled, the maximum rate is 1 GS/s per channel. Disable the unused channel and enable time-interleaved sampling to acquire one channel at 2 GS/s.
The acquired waveform is clipped
Select a larger input range or adjust the vertical offset. Verify that the complete signal, including DC offset, noise and overshoot, remains within the configured range.
The measured amplitude is incorrect
Check input impedance and source termination. A generator calibrated for a 50 Ω load can produce approximately twice its indicated open-circuit voltage when connected to a 1 MΩ input.
The signal contains reflections
Use 50 Ω coaxial cables and matching termination for high-frequency sources. Remove unterminated branches and minimize adapters or fixture discontinuities.
RIS produces an unstable waveform
Random-interleaved sampling requires a stable repetitive signal. Use 1 GS/s dual-channel or 2 GS/s single-channel real-time acquisition for nonrepetitive events.
The trigger is unstable
Review the trigger source, level, slope, coupling and hysteresis. Confirm that the trigger signal crosses the threshold with sufficient slew rate.
The 100 mV range does not reach 300 MHz
The smallest input range has reduced analog bandwidth. Select a larger range or add an appropriate external low-noise amplifier when both sensitivity and bandwidth are required.
Multiple modules are not synchronized
Confirm that all modules share the same reference clock and trigger source. Configure the NI-TClk group, clock master and trigger routing correctly.
