The Curtiss-Wright/VMETRO PBTM-515B is a third-generation PCI and PMC bus analyzer delivering real-time monitoring, debugging, and performance analysis in a single-slot PMC module. It functions as a complete logic analyzer for 64-bit and 33/66 MHz systems, enabling engineers to capture deep bus transaction insight, identify hardware and software issues rapidly, and validate system behavior across aerospace, defense, and industrial platforms.
## Technical Specifications
• **Bus Standards:** PCI version 2.3 compliant; PMC module form factor
• **Bus Width:** Supports 32-bit and 64-bit PCI buses
• **Clock Speeds:** 33 MHz and 66 MHz systems; up to 66.7 MHz operation
• **Signaling Levels:** 3.3V and 5V signaling support
• **Trace Memory:** 64K depth (PBTM-515B model)
## Key Features
**State Analyzer Capabilities**
• Three standard sampling modes: CLOCK, TRANSFER, and TRANSACTION; optional 500 MHz Timing Analyzer adds fourth mode
• Clock-by-clock sampling for low-level hardware protocol analysis via bus interface state machines
• Advanced triggering and filtering with 16-level Trigger/Qualifier Sequencer
• Multi-level triggering with trigger-after-delay or event-count logic
• Four full-speed Word Recognizers supporting true Address and Data Range definitions
• Address, command, and data de-multiplexing into separate trace channels
• Time tags in trace buffer indicating sample intervals
• Latency counter measuring target latency (FRAME# to TRDY#) and wait states between data transfers
**Exerciser Capabilities** (with optional EXERBAT companion board)
• Bus Master interface with DMA support
• Target interface with 8 MB zero-wait-state burst memory
• DMA transfers between Exerciser and target, or between two bus targets
• Interrupt generation and handling
• Burst and Single cycle support
• Memory test patterns: walking ones/zeros, random patterns
• Built-in Script Recording and Playback with programmable delay and loop functions
## Typical Applications
Aerospace and defense system development; industrial embedded PCI and PMC platform validation; real-time hardware-software co-verification.
## Compatibility & Integration
Member of PBT-515 product family. Pairs with EXERBAT exerciser board for combined analysis and stimulus capabilities. Compatible with 32/64-bit PCI systems operating at 33/66 MHz with both 3.3V and 5V signaling.
