Agilent/Keysight 10529A

The Agilent/Keysight 10529A is an in-circuit logic comparator for troubleshooting digital logic failures in TTL and DTL circuits. It identifies faulty nodes and integrated circuits by comparing a suspected faulty IC against a known-good reference IC, eliminating the need for desoldering.

Technical Specifications

• Input Threshold: 1.4 V nominal (1.8 V nominal with socket board); TTL/DTL compatible


• Test IC Loading: Outputs driving Test IC inputs loaded by 5 low-power TTL loads plus Reference IC input; Test IC outputs loaded by 2 low-power TTL loads


• Input Protection: Voltages 7 V must be current-limited to 10 mA


• Supply Voltage: 5 V ± 5%; maximum 7 V


• Maximum Current Consumption: 300 mA


• Error Detection Sensitivity: 200 ns with reference board; 300 ns with socket board. Errors exceeding these durations are stretched to minimum 0.1 seconds


• Spurious Rejection: Errors shorter than 50 ns are ignored


• Maximum Operational Frequency: 3 MHz for full-cycle error detection


• Operating Temperature: 0 °C to 55 °C

Key Features

• In-circuit troubleshooting without component removal


• Dynamic error stretching and display


• Switch-programmable socket board included


• Self-powered, self-contained operation


• Suitable for use in digital feedback loops


• Rapid multi-IC screening capability

Typical Applications

• Locating bad nodes in TTL and DTL logic circuits


• Field troubleshooting of digital system failures


• IC fault isolation without PCB rework

Compatibility & Integration The 10529A operates with TTL and DTL logic families and requires a known-good reference IC for comparative analysis. It functions independently or in conjunction with other IC troubleshooters. Product Status: Discontinued. Documentation available for reference.
