Logic Analyzer Reference
The Analyzer Format Menu
Setup/Hold field
Setup/Hold in the Master and Slave Clock fields adjusts the relative
position of the clock edge with respect to the time period that data is
valid. When the Setup/Hold field is selected, a configuration menu
appears. Use this Setup/ Hold configuration menu to select each pod in
the analyzer and assign a Setup/Hold selection from the selection list.
With a single clock edge assigned, the choices range from 3.5-ns Setup/
0.0-ns Hold to 0.0-ns Setup/3.5-ns Hold. With both edges of a single
clock assigned, the choices are from 4.0-ns Setup/0.0-ns Hold to 0.0-ns
Setup/4.0-ns Hold. If the analyzer has multiple clock edges assigned,
the choices range from 4.5-ns Setup/0.0-ns Hold to 0.0-ns Setup/4.5-ns
Hold.
The relationship of the clock signal and valid data under the default
setup and hold is shown in the upper figure. If the relationship of the
clock signal and valid data is such that the data is valid for 1 ns before
the clock occurs and 3 ns after the clock occurs, you will want to use
the 1.0 setup and 2.5 hold setting as shown in the lower figure.
