Automate measurement setup

and quickly gain diagnostic

clues

16850 Series logic analyzers make

it easy for you to get up and running

quickly by automating your measure-

ment setup process. In addition, the

logic analyzer’s setup/hold window

(or sampling position) and threshold

voltage settings are automatically

determined so you can capture data

on high-speed buses with the highest

accuracy. Auto Threshold and Sample

Position mode allow you to...

• Obtain accurate and reliable mea-

surements

• Save time during measurement

setup

• Gain diagnostic clues and identify

problem signals quickly

• Scan all signals and buses simulta-

neously or just a few

• View results as a composite dis-

play or as individual signals

• See skew between signals and

buses

• Find and fix inappropriate clock

thresholds

• Measure data valid windows

• Identify signal integrity problems

related to rise times, fall times,

data valid window widths

Figure 2. Eye scan automatically sets sample positions for accurate state capture

and also provides a signal integrity view of each input signal, without the need for an

oscilloscope.

Eye Scan to Set Sample Points and to View Signal Integrity

Identify problem signals over one hundred channels simultaneously

As timing and voltage margins continue to shrink, confidence in signal integrity

becomes an increasingly vital requirement in the design validation process. Eye

scan lets you acquire signal integrity information on all the buses in your design,

under a wide variety of operating conditions, in a matter of minutes. Identify

problem signals quickly for further investigation with an oscilloscope. Results

can be viewed for each individual signal or as a composite of multiple signals or

buses.
