Interface
Description
The HP 10343B provides a complete mechanical and electrical interface
between the HP 1630A/D/G or HP 1631A/D and your 8 Bit SCSI Bus
system. This interface allows the logic analyzer to capture and decode all
of the activaties on the SCSI bus. The SCSI bus is detected by high
impedence comparitors on the HP 10343B. The outputs of these
comparitors go directly to the logic analyzer for timing analysis.
For state analysis, the SCSI phase activities are decoded by the Phase
Detection Logic. The logic analyzer clock is sent out at the correct times
to capture the data.
