This unit
The Agilent/Keysight 34522B is a 32-bit digital I/O module engineered for parallel data acquisition and control within the HP 3235 Mainframe ecosystem. It has 32 bidirectional TTL-compatible data lines organized into four independent 8-bit ports, each with dedicated handshake control. Ports operate flexibly as individual read/write channels or combine for 16-bit and 32-bit parallel transfers.
The module delivers read/write rates exceeding 40 kHz, supporting time-critical applications requiring deterministic data exchange.
Technical Specifications
- Data Lines: 32 bidirectional, TTL-compatible
- Port Architecture: Four 8-bit ports with independent handshake lines
- Configurable Data Transfer: 8-bit, 16-bit, or 32-bit parallel operation
- Interrupt Lines: 8 edge-triggered
- High-Power Outputs: 16 FET outputs
- Data Rate: Greater than 40 kHz read/write
Key Features
- Flexible port configuration enables independent or combined operation for mixed-width parallel transfers
- Edge-triggered interrupt architecture supports responsive event handling in control applications
- High-power FET outputs drive external loads without additional buffering
- TTL signal levels ensure compatibility with standard digital logic families
- Modular design integrates directly into mainframe-based test and measurement systems
Typical Applications
- Automated test equipment (ATE) requiring parallel digital control and monitoring
- Real-time data acquisition from multiple sensor and device interfaces
- Industrial process control with deterministic timing requirements
- Hardware-in-the-loop simulation platforms
- Multi-channel digital signal routing and switching
Compatibility & Integration The 34522B works with the HP 3235 Mainframe, providing seamless integration into modular measurement platforms.
Agilent / Keysight 34522B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 34522B. Calibration covers per-channel threshold accuracy, input leakage current, logic level high/low margins, and signal timing verification. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight 34522B faults: ESD-damaged input protection, failed driver ICs, connector pin damage. Most failures involve ESD-damaged input protection circuitry, failed logic driver ICs, or mechanical connector pin damage. Board-level component replacement is standard practice.
