Curtiss-Wright / VMETRO PBTM-515B Bus Analyzer

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, capture deep bus transaction insight, identify hardware and software issues rapidly, and validate system behavior across aerospace, defense, and industrial platforms.

Technical Specifications

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
