SCS-320 and SCS-160 SCSI
The SCSI Analyzer is
typically used for monitoring, recording, and playing back the activity
occuring on a SCSI Bus. It auto-configures for Single-Ended or LVD
modes, and supports transfers from Asynchronous through 320/m on the SCS-320,
and through 160/m on the SCS-160. The SCSI Bus is used for a wide range of
storage devices, such as Hard Drives, Tape Drives, RAID Systems, Optical
Devices, CD-ROM's, and Storage Juke Boxes. It is also used for Printers and
Scanners. The SCSI Analyzer supports all of the various commands used on these
devices, while being easy-to-use, powerful, portable, versatile, and
cost-effective. It is a true stand alone instrument overcoming the
configuration drawbacks of PC-based analyzers, yet it is PC connect-able.

The analyzer uses a
"Transitional Time-Stamping" Capture method in both State and Timing
modes. This capture technique provides the ability to run for days
without filling the buffer when little activity is occuring. The analyzer can
show the time elapsed between events which are up to 999 seconds apart.
Timing Mode (Raw)
captures every signal transition. This can be viewed in waveform windows.
State Mode (Normal)
uses the buffer more efficiently by only capturing events on the specific
Whichever mode is used,
the State Listing and Timing Waveform displays can still be used to view the
The analyzer provides a
number of Loadable USB Triggering files, which configure the analyzer
to trigger on events that otherwise might be difficult to trigger on, due to
the complexity of the trigger event sequence.
These triggers include:
- Trigger on Check
- Trigger on Command
- Trigger on Wide
- Trigger on Synchronous
- Trigger on Parallel
- Trigger on Queue Tag
- Trigger on a Queue Full
The analyzer also provides a Powerful
8x7 Trigger Sequencer Array which is user-programmable to trigger on a
sequence of events. The triggering includes Counter and Timer levels,
and is unique in the industry due to its ability to branch to different
sequences depending on which events occur first on the bus.
The analyzer provides a
variety of Easy SCSI Filtering selections, which automatically
configure the capture to only store what the user is interested in.
These Filters include:
- Store a
user-selected portion of the data in each block, then Filter the
- Store activity for specific
The Filter Sequencer
is user programmable, and can Start or Stop capturing on any
user-defined events.The sequencer includes three Variable Sequence
Counters which allow the user to capture a specified number of
certain events and then begin filtering.
In addition to Sequence Filtering, Event Filtering is also
available. Any of the states captured in State Mode can be defined more
specifically to allow only a subset of the normally captured states. For
example, the "Info Xfer Phase" states can be redefined to
capture only Command and Status transfers.
The SCSI 320 pod
requires a Tektronix TLA-600 or TLA-700 series analyzer with ( 1 ) 68
channel, 200Mhz module, while the SCSI 160 pod requires a TLA-600 or
TLA-700 with (1) 68 channel, 100Mhz module.
