SCSI Pod for Bus Doctor Analyzer

The SCSI 320 Pod turns the Bus Doctor into a full-featured protocol analyzer, with the depth, ease-of-use, protocol decoding and statistics needed by software and systems testers. It also provides the features needed by hardware engineers including multi-level triggering, filtering, state configuration and timing analysis of SE and LVD transfers.

SCSI 320 Displays
At the Command level, the SCSI 320 analyzer provides a big-picture view for testers who are troubleshooting system-level or application-level issues. The State display provides register-level access details for users who need to monitor SCSI 320 software, device drivers or firmware. For hardware engineers, the Timing Waveform display provides for analysis of SCSI 320 signal activity.

SCSI 320 Capturing
The SCSI 320 analyzer provides several predefined capture configurations:

• Timing Mode - (Store all transitions)
• State Mode
  • All Valid States
  • Valid States with Training Sequence
  • Packetized Non-Paced

Custom State Modes can also be created. You may select quick arbitration selection (QAS).

SCSI 320 Triggering
The SCSI Analyzer provides high-level trigger configurations for most common trigger scenarios. The high-leve user dilogs that alllow you to set triggers on a variety SCSI protocol components includings commands, messages, status, any phase, and the ITLQ nexus. You may set triggers for packetized and non-packetized environments. You may also set up customer triggering.

SCSI 320 Trace Filtering
The SCSI 320 Analyzer provides commonly used high-level filter configurations. Many of the high-level filters provide drop-down boxes for configuration options. Users can also create and save custom filters. After capturing, the Show/Hide control allows you to filter the contents of the trace with options for both the Command and State listings.

SCSI 320 Statistics
The Real-Time Monitor can be easily configured so you can see interesting and usable bus statistics while taking a trace or at any other time.
