Keysight Technologies 68-Channel Portable Logic Analyzer Model customized-14

Overview

The Keysight Technologies 68-Channel Portable Logic Analyzer Model customized-14 is a high-fidelity digital signal acquisition and analysis platform engineered for rigorous embedded system validation, FPGA verification, and protocol-level debugging in resource-constrained or field-deployed environments. Unlike conventional benchtop logic analyzers, this instrument integrates state-of-the-art asynchronous timing capture with synchronous state analysis—leveraging dual-domain sampling architecture to resolve both deterministic clock-aligned behavior and non-deterministic signal anomalies. Its core measurement principle relies on parallel high-impedance CMOS input receivers synchronized to user-defined reference clocks (for state mode) or driven by ultra-stable internal timebases (for timing mode), enabling precise edge detection down to 80 ps resolution. Designed for compliance with IEEE 1149.1 (JTAG) and industry-standard bus protocols including I²C, SPI, UART, PCIe Gen3, and MIPI D-PHY, the analyzer supports real-time protocol decode, triggering, and correlation across all 68 channels without channel masking or bandwidth throttling.

Key Features

• 68 fully independent, high-impedance (1 MΩ || 10 pF) digital input channels with individually configurable threshold voltage and hysteresis settings
• Dual-mode acquisition engine: state analysis at up to 700 MHz clock rate and 1.4 Gb/s data throughput; timing analysis at up to 10 GHz equivalent sample rate (quarter-channel mode)
• 15-inch industrial-grade capacitive touchscreen with glove-compatible operation and customizable UI layout for rapid waveform navigation
• Onboard removable NVMe SSD (up to 1 TB capacity) supporting concurrent capture-to-disk streaming at sustained 1.2 GB/s write speeds
• Programmable 1.4 GHz trigger sequencer with nested conditional logic, deep pattern memory, and hardware-accelerated serial protocol matching
• Gigabit Ethernet and USB 3.0 interfaces compliant with USB Device Class Definition for Test & Measurement (USBTMC-USB488)
• Ruggedized magnesium alloy chassis rated IP52 for dust resistance and transient shock protection (MIL-STD-810H compliant)

Sample Compatibility & Compliance

The analyzer supports direct probing of LVCMOS, LVTTL, SSTL, HSTL, and differential standards including LVDS and RSDS via optional active probe modules. All input channels feature auto-ranging threshold detection calibrated traceably to NIST-traceable references. The instrument complies with IEC 61000-4-2 (ESD immunity), IEC 61000-4-3 (radiated RF immunity), and CISPR 32 Class B emission limits. Firmware and embedded software are developed under Keysight’s ISO 9001-certified design control process and support audit-ready configuration management per FDA 21 CFR Part 11 requirements when deployed in regulated development labs. Protocol decoders undergo annual conformance testing against official specification documents from JEDEC, PCI-SIG, and MIPI Alliance.

Software & Data Management

The bundled PathWave Logic Analyzer Software (v24.x) provides hierarchical signal grouping, multi-bus decode stacking, and cross-domain correlation between timing waveforms and state-based protocol views. All captured datasets include embedded metadata (timestamp, trigger context, hardware configuration hash) and support HDF5-based export for integration with MATLAB, Python (NumPy/Pandas), or LabVIEW environments. Role-based access control, encrypted project files, and immutable audit logs meet GLP/GMP documentation requirements. Remote operation is supported via RESTful API over HTTPS, enabling integration into CI/CD pipelines for automated regression testing of firmware revisions.

Applications

• FPGA bring-up and timing closure validation under real-world clock skew and jitter conditions
• Low-power IoT subsystem debugging using deep-sleep wake event correlation across multiple sensor interfaces
• Automotive ECUs validation against AUTOSAR-compliant CAN FD and LIN timing constraints
• High-speed memory interface characterization (DDR4/5, LPDDR4/5) using eye diagram overlay and jitter decomposition
• Security-critical SoC side-channel analysis requiring long-duration, gap-free capture across cryptographic peripheral buses
• Academic research in asynchronous circuit design and metastability propagation modeling

FAQ

What is the maximum sustained capture duration at full 68-channel, 2.5 GHz timing mode?
At full channel count and 2.5 GHz sample rate, the standard 2 Mb memory supports ~800 ns of continuous capture. Extended memory options enable up to 1.2 ms capture window at this rate.
Does the instrument support hardware-accelerated protocol triggering for PCIe Gen4?
No—PCIe Gen4 (16 GT/s) exceeds the maximum timing sample rate. However, Gen3 (8 GT/s) link-layer transactions can be triggered and decoded using the built-in hardware pattern matcher.
Can the SSD be replaced or upgraded by the end user?
Yes—the M.2 2280 NVMe slot is user-accessible and supports third-party drives meeting Keysight’s thermal and power specifications (tested models listed in the Hardware Maintenance Guide).
Is remote scripting supported via Python or MATLAB?
Yes—Keysight I/O Libraries Suite (version 2024+) includes native Python bindings and MATLAB Instrument Control Toolbox compatibility with SCPI command set extensions specific to logic analysis functions.
How is calibration maintained during field deployment?
The unit performs automatic internal reference calibration at power-on and every 24 hours during continuous operation. Full external calibration is recommended annually per Keysight Calibration Services Technical Bulletin 5992-2601EN.
