HP 64794C 64K Trace Depth Emulation Bus Analyzer

The HP 64794C Emulation Bus Analyzer offers a trace buffer depth of 64K for capturing data. This analyzer has the triggering, sequencing, and qualification features necessary to provide real-time, transparent measurements common in embedded systems. Additionally, you can precisely position your measurement deep within complex embedded code. Then, in real-time, you can capture large quantities of data around the specified event.

[ Features ]

64K trace depth for capturing data.
Measurements include address, data, and status buses plus time and state count for compatible HP 16-and 32-bit emulators.
Eight full width hardware resources can be combined in sequential trace specifications using "find A followed by B..." constructs up to eight levels deep.
32-bit range comparators can be combined with any of the eight hardware resources at any level to specify exclusive areas for triggering or data capture.
Precise time tagging of events helps locate discrepancies in execution times. State and time counts are supported over the entire memory depth.
Prestore state can show an event occurring sometime before each stored event. You can observe which of several different functions is accessing a variable and corrupting it.
Receives and drives trigger signals to/from other HP 64700 series emulators/analyzers, logic analyzers, or oscilloscopes.
