Keysight EXR258A – Digital Oscilloscope (2.5 GHz / 8 Channels)

Description

The Keysight EXR258A digital storage oscilloscope isolates critical propagation delays across dense, multi-phase high-speed serial bus loops. This eight-channel instrumentation system projects real-time electrical trace metrics onto an expansive 15.6-inch visual tracking workspace, allowing automated test engineers to verify concurrent horizontal clock deviations and asynchronous glitch signatures without picking up nearby facility electromagnetic floor noise floors.

By unifying a 2.5 GHz bandwidth architecture with a blistering 16 GS/S maximum real-time sampling rate, an ultra-fast 172 ps sub-nanosecond rise time, and a 100 Mpts deep waveform memory allocation, the platform maintains superior signal integrity. The specialized multi-instrument framework incorporates a native 10-bit vertical resolution digitizer and an integrated 16-channel logic analyzer to minimize quantization errors and accelerate cross-domain debugging throughput.

Key Features of Keysight EXR258A

• Eight Analog Input Channels: Coordinates concurrent timing analysis across eight decoupled multi-phase power distribution networks.
• 10-Bit Vertical Quantization Depth: Cuts quantization errors fourfold, uncovering microvolt noise masked on standard 8-bit systems.
• High-Speed 16 GS/S Sampling: Details fast transient reflections and impedance mismatches along 2.5 GHz circuit nodes.
• 2.5 GHz Base Bandwidth: Profiles high-speed serial bus data streams and high-frequency microwave communications lines.
• 16 Integrated Logic Channels: Maps multi-channel firmware register outputs synchronously with analog power sequencing rails.
• 100 Mpts Waveform Memory: Stores dense telemetry datasets without reducing digitizer sample rates across extended measurements.
• 200,000 wfms/s Update Engine: Isolates transient clock path failures by eliminating long dead-time diagnostic intervals.

High-Density Multichannel Microwave Signal Capture

The core processing layer leverages a premium 10-bit vertical resolution digitizer combined with an ultra-fast 172 ps rise time and an exceptional 16 GS/S real-time sampling rate to eliminate configuration latency during unpredictable circuit evaluations. This eight-channel configuration enables automated test engineers and firmware developers to view elusive low-amplitude anomalies and random clock jitter across eight separate signal lines simultaneously without risking signal attenuation near the Nyquist frequency limit. All real-time waveforms pass directly through the integrated digitizer to achieve a superior signal-to-noise ratio and isolate delicate signal paths from ambient electromagnetic facility noise floor interference.

Aerospace Infrastructure and Asset Lifecycle Protection

Constructed to excel in automated testing environments (ATE), high-volume production benches, and advanced engineering laboratories, the heavy-duty enclosure optimizes workbench space while providing a 36.8 lbs shipping weight footprint built for secure long-distance logistics. The multi-instrument layout native to the EXR-Series framework packages critical digital logic mapping and multi-channel parametric testing right on the bench, ensuring immediate automated data extraction over standard communication loops without structural baseline thermal drift. Guaranteeing long-term corporate asset protection, the test instrument comes standard with a verified 3-Year Warranty framework to ensure continuous equipment dependability.
