The Agilent 16910/11A Logic Analyzers—At a Glance
The Agilent Technologies 16910A and 16911A are logic analyzer modules for the
Agilent Technologies 16900-series logic analysis system. The 16910/11A offers
high performance measurement capability.
Features
Some of the main features of the 16910/11A are as follows:
• 98 data channels (16910A)
• 64 data channels (16911A)
• 4 clock/data channels
• 256 K to 64 M memory depth per channel (depends upon option chosen)
• 500 Mb/s maximum state data rate (with Option 500)
• 1 GHz, 128 M deep timing analysis on half channels
• “Eye Finder” feature
• 4 GHz timing zoom with 64 k memory depth
• Expandable to 340 channels (16911A) or 510 channels (16910A) on a single clock
Service Strategy
The service strategy for this instrument is the replacement of defective
assemblies. This service guide contains information for finding a defective
assembly by testing and servicing the 16910/11A state and timing analyzer
module.
The modules can be returned to Agilent Technologies for all service work,
including troubleshooting. Contact your nearest Agilent Technologies Sales
Office for more details.
Application
This service guide applies to a 16910A or 16911A module installed in the 16900-
series logic analysis system mainframes.
