The VXI Technology 4016-2-S-11015 is an analog comparator and interrupt module for VXIbus systems that enables high-speed threshold detection and event signaling across 16 true differential input channels. Each channel independently detects when input signals exceed software-defined bounds and triggers either a VXIbus interrupt or front panel interrupt, making it ideal for go/no-go testing and voltage-level monitoring in automated test and control applications.
Technical Specifications
• Module Type: Analog Comparator/Interrupter Module
• Form Factor: VXIbus C-size, single-wide
• Analog Input Channels: 16 true differential channels
• Input Type: Differential
• Input Polarity: Programmable (normal or inverted sense)
• Debounce Time: 10 µs to 0.6291456 s (programmable)
• VXIbus Interface: Message-based, word serial with direct register access for high-speed data retrieval
• Command Standard: SCPI-compliant command set
• Driver Support: VXIplug&play drivers supported
– Key Features
• Each channel triggers interrupts when input signals exceed programmed thresholds or exit software-defined windows
• Inputs can be masked, inverted, and logically combined; all enabled inputs are OR’d to generate a single interrupt signal
• Digitally debounced inputs prevent false interrupts from noise
• Front panel interrupt output is latched; VXIbus interrupt is also generated
• Dual-path data access: message-based (SCPI) and direct register access for throughput-critical operations
• Unused channels can be masked to prevent unwanted interrupt generation
– Typical Applications
• Go/no-go voltage verification where test failure occurs when outputs exceed programmed limits
• Safety shutdown and control circuits requiring immediate response to voltage threshold violations
• High-density automated test equipment requiring event-driven interrupt handling
– Compatibility & Integration
The module integrates within the VMIP™ (VXI Modular Instrumentation Platform) family, allowing consolidation of multiple instrument functions in a single C-size slot. This reduces overall system size and cost while enabling integration with other VMIP™ modules such as the VM1602 Time Stamp module.
