The National Instruments PXIe-5160 is a PXI oscilloscope module with two analog input channels, 500 MHz analog bandwidth, 2.5 GS/s sampling, and 10 bit resolution. The module is designed for high speed signal acquisition, electronic validation, automated test, and research applications that require waveform capture in a modular instrument platform.
Oscilloscopes convert analog waveforms into digital data for analysis. The PXIe-5160 brings high bandwidth acquisition to the PXI Express platform. Engineers can capture fast transients, measure signal quality, and analyze frequency content using software.
High Bandwidth Acquisition
The PXIe-5160 provides two analog input channels with 500 MHz bandwidth and 2.5 GS/s sampling. The high sampling rate supports capture of fast signals and short transients. The 10 bit resolution provides amplitude detail beyond standard 8 bit oscilloscopes.
Engineers should configure input range, coupling, and trigger settings for the signal. Proper probes and cabling are important for signal integrity at high frequencies. Calibration and verification help maintain accuracy.
Triggering and Data Capture
The module supports triggering for capturing events at the right time. Engineers can use edge, window, and other trigger modes. Triggering helps capture transients, pulses, and repetitive waveforms. Data can be stored in onboard memory and transferred to the host.
For automated test, triggering can be synchronized with stimuli and other instruments. The PXI Express backplane provides timing resources for multi instrument coordination.
PXI Express Integration
The PXIe-5160 operates in compatible PXI Express chassis. It can be combined with controllers, signal generators, switches, and DAQ modules. The PXI Express backplane supports high speed data transfer and timing synchronization.
System integration should consider chassis power, cooling, slot compatibility, and cabling. Test fixtures should provide stable connections and shielding.
Software and Analysis
The module is controlled through NI software and standard programming environments. Engineers can configure acquisition, triggers, and data transfer. Software can perform frequency analysis, amplitude measurement, and waveform characterization.
Applications
The PXIe-5160 is suited to electronic validation, automated test, transient capture, signal integrity analysis, and research. In a test station, it can capture device responses to stimuli. In a laboratory, it can analyze fast waveforms and noise.
Installation and Maintenance
Installation requires a compatible PXI Express slot, proper cabling, and a test fixture designed for the signal frequency and amplitude. Input connections should be shielded where appropriate. The chassis should provide adequate cooling and power.
Maintenance includes calibration, connector inspection, and verification of acquisition settings. Documentation helps troubleshooting.
Summary
The National Instruments PXIe-5160 Oscilloscope provides two channel 10 bit acquisition at 2.5 GS/s with 500 MHz bandwidth for PXI Express systems. It supports high speed waveform capture, automated test, and electronic validation. The PXIe-5160 is a practical oscilloscope for engineers who need modular high bandwidth signal acquisition.
