In the debugging and validation of complex digital systems, multi-core processors, and high-speed backplanes, engineers often need to simultaneously observe the timing relationships of dozens or even hundreds of high-speed signals. The limited channel count of traditional oscilloscopes becomes a bottleneck. The Keysight T1141A Probe Amplifier System, through its innovative modular design, expands one or two oscilloscope input channels into up to 16 high-bandwidth probing channels, providing a powerful front-end solution for multi-channel logic state and timing analysis.
To ensure that such precision multi-channel probing systems maintain excellent signal fidelity and channel-to-channel consistency over the long term, professional calibration, maintenance, and system validation support are indispensable. Shenzhen Bao'an District Shajing Fangfengrui Instrument Equipment Business Department possesses specialized expertise in the field of multi-channel high-speed probing system services and can provide comprehensive technical support and service assurance for T1141A users.
T1141A: The Modular Probing System That Expands Oscilloscope Vision
Core Performance and Technical Features:
Efficient Channel Expansion: A single T1141A mainframe can accommodate 2 probe amplifier modules, each providing 8 probing channels. This transforms 1 or 2 analog input channels of an oscilloscope into 8 or 16 logic probing channels, significantly enhancing the capability for synchronous observation of multi-lane parallel buses (e.g., DDR address/data lines, multiple FPGA I/Os).
Excellent Electrical Performance and Signal Integrity: Each channel offers up to 2 GHz bandwidth (-3 dB), accurately capturing the edges and transients of high-speed digital signals. Features extremely low input capacitance (typical < 1 pF) and high input impedance to minimize loading effects on the device under test. Channel-to-channel deskew is adjustable to compensate for minor timing differences caused by cable length variations, ensuring accurate multi-channel time correlation.
Flexible Module Configuration and Probe Selection: Offers amplifier modules (e.g., N2780A series) with different bandwidths and attenuation ratios. Users can flexibly select based on signal voltage range (e.g., ±8 V, ±16 V) and speed requirements. Compatible with various micro-pitch probe accessories for easy connection to test points on compact packages like Fine-pitch BGA and QFP.
Convenient Power Supply and Integration: The mainframe is powered and communicates directly via a dedicated cable from a compatible oscilloscope (e.g., Keysight InfiniiVision or Infiniiium series), eliminating the need for an external power supply and simplifying setup. Features automatic recognition and configuration, with the oscilloscope interface directly displaying identifiers and settings for all expanded channels.
Typical Application Scenarios:
High-Speed Parallel Bus Analysis: Synchronously observe dozens of data and control lines of DDR memory or Flash interfaces to analyze setup/hold times and timing synchronization.
Multi-Channel Digital System Debugging: Simultaneously monitor multiple GPIOs and control signal groups of FPGAs or ASICs to locate complex state machine errors or cross-signal interference.
Power Sequencing and Monitoring: Simultaneously measure the power-up/down sequencing, ripple, and glitches of multiple power rails on a circuit board.
Embedded System Hardware Validation: Correlate activities across multiple peripheral interfaces in multi-core processor systems for system-level hardware validation.
Professional Services Ensure Multi-Channel Probing System Performance
For multi-channel systems like the T1141A, the core of performance assurance lies in the bandwidth and frequency response consistency of each channel, the channel-to-channel skew matching, the electrical contact reliability of probe connectors, and the gain/offset accuracy of the entire system.
Shenzhen Bao'an District Shajing Fangfengrui Instrument Equipment Business Department can provide users with critical support in this area:
Full-Channel Frequency Response and Bandwidth Calibration: Calibrates the bandwidth, rise time, and frequency response flatness of each probing channel using high-speed network analyzers or pulse generators to ensure signal fidelity.
Channel-to-Channel Skew Measurement and Matching: Precisely measures the relative propagation delay between all channels and performs software or hardware adjustments to achieve precise time alignment across channels, which is crucial for multi-channel timing analysis.
Gain, Offset, and Threshold Accuracy Calibration: Calibrates the vertical gain (attenuation ratio), DC offset, and logic threshold level of each channel to ensure accurate voltage measurement.
Probe and Connector Inspection and Maintenance: Inspects the physical condition and electrical contact performance of all probe tips, cables, and connectors, providing cleaning, repair, or replacement services.
System Integration and Oscilloscope Compatibility Verification: Verifies that the T1141A's power supply, communication, and automatic recognition functions operate correctly with the user's specific oscilloscope model.
Fault Diagnosis and Module-Level Repair: Provides professional diagnosis for faults such as no signal, reduced bandwidth, excessive noise, channel-to-channel crosstalk, and communication interruption, along with module or mainframe repair services.
