The Keysight/Agilent/HP 16500A Logic Analyzer Mainframe is a modular platform that integrates logic state analysis, timing analysis, digitizing oscilloscope, and digital pattern generation into a single instrument. The mainframe provides five measurement module slots, each accommodating state/timing cards, timing cards, pattern generator cards, or digitizing oscilloscope modules to customize the system for specific debug, characterization, integration, or pass/fail testing requirements. An optional expansion frame increases total slots to nine for complex applications.
## Technical Specifications
**Mainframe Architecture**
• Five measurement module slots (nine total with optional expansion frame)
• Time-correlated measurements across modules via intermodule bus
• Support for simulation vectors enabling comparison of design simulation data with actual hardware measurements
**User Interface**
• 9-inch color touchscreen display
• Front panel knob and pop-up menu control
• Optional mouse input; later models (16500C) include DIN connectors for PS-2 keyboard and mouse
• Fully programmable
**Data Management**
• Two built-in 3-inch floppy disk drives for setup storage and test data archival
• File load, format, store, and rename capabilities
• Instant hardcopy output to graphics printers
## Key Features
• Modular design accommodating diverse measurement card types
• Expandable architecture supporting up to nine total measurement slots
• Single-instrument integration of four analyzer types eliminates need for separate instruments
• Intermodule bus enables synchronized, time-correlated analysis across different measurement domains
## Typical Applications
• Digital system debug and fault isolation
• Design characterization and hardware verification
• Systems integration testing
• Pass/fail production testing with simulation vector comparison
## Compatibility & Integration
The 16500A accepts a wide range of Keysight/Agilent/HP measurement modules. Module compatibility varies; users should consult manufacturer documentation for specific module selection. The system interfaces via HP-IB (GPIB) for remote programmability and integration into automated test environments.
