Preprocessor
Function
This chapter explains how to connect the HP 1Q343B SCSI Bus
Preprocessor between your 8-Bit Single-Ended or Differential SCSI Bus
system and the HP 1630A/D/G or HP 1631A/D Logic Analyzer. This
includes loading the inverse assembler and configuring the logic analyzer.
The HP 10343B SCSI Bus Preprocessor consists of an interface module
which plugs into the HP 10269A/B General Purpose Probe Interface. The
connectors on the HP 10343B accept both shielded and nonshielded SCSI
bus cables which allow it to be connected quickly and easily into your
SCSI Bus system. Switches on the front panel allow you to the select the
appropriate bus type, parity, and SCSI lines to look at with timing. LED
lights as indicators allow you to look at the static condition of the bus at a
quick glance. The interface may be used with the HP 1630A/D/G and HP
1631A/D Logic Analyzers.
There are ten inverse assemblers available that can be loaded into the
logic analyzer. This gives you the flexiblity of selecting the appropriate
inverse assembler to decode any of the ten different device types that are
called out in the SCSI Standard X3T9.2/86-109 Revision 2. Tliese inverse
assemblers are all compatable to the HP 1630A/D/G and HP 1631A/D
Logic Analyzers.
