Before I send a new major firmware release to customers I verify that it is tested and endorsed by the team at Medusa Labs. Nobody does a better job of testing products under extreme conditions.

Bus Doctor™ SCSI Protocol Analyzer

View Enlarged Image

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.

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.

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).

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.
