Testing Logic Analyzer Performance

determine performance which is better than specifications.
Not all channels of the logic analyzer will be tested; a
sample of channels is tested. The calibration laboratory may
choose to elaborate on these tests and test all channels at
their discretion.
Eye Finder is used to adjust the sampling position on every
channel. Eye Finder must be used to achieve maximum state
data rate performance.
The 2 Gb/s state logic analyzer will be tested. Both clocks
(Clk1 and Clk3) will be tested. All four pods will be tested,
one pod at a time.
The logic analyzer acquires data on both edges of the clock,
so the test frequency is set to half of the acquisition speed.
One-card Module
To perform a complete test on a one- card module, start at
the beginning of the chapter and follow each procedure.
Multi-card Module
To perform a complete test on a multi- card module, perform
the self- tests with the cards connected. Then, remove the
multi- card module from the mainframe and configure each
card as a one- card module. Install the one- card modules
into the mainframe and perform the performance
verification tests on each card. When the tests are complete,
remove the one- card modules, reconfigure them into their
original multi- card module configuration, reinstall it into the
mainframe and perform the self- tests again. These steps are
necessary to ensure that the clocks are tested on each
module.
Instructions for removing and installing the module can be
found in the installation guide for the mainframe.
If you don't have the installation guide for your mainframe,
you can find the latest version on the Internet at
www.agilent.com.
