Using The Timing Analyzer
Introduction
Problem Solving with the Timing Analyzer
In this chapter you will learn how to use the timing analyzer by setting up the logic analyzer to make a simple measurement. We give you the measurement results as actually measured by the logic analyzer, since you may not have the same circuit available.
The exercise in this chapter is organized in a task format. The tasks are ordered in the same way you will most likely use them once you become an experienced user. The steps in this format are both numbered and lettered. The numbered steps state the step objective. The lettered steps explain how to accomplish each step objective. There is also an example of each menu after it has been properly set up.
How you use the steps depends on how much you remember from chapters 1 through 5. If you can set up each menu by just looking at the menu picture, go ahead and do so. If you need a reminder of what steps you need to perform, follow the numbered steps. If you still need more information about "how," use the lettered steps.
In this exercise, assume you are designing a dynamic RAM memory (DRAM) controller and you must verify the timing of the row address strobe (RAS) and the column address strobe (CAS). You are using a 4116 dynamic ram and the data book specifies that the minimum time from when LRAS is asserted (goes low) to when LCAS is no longer asserted (goes high) is 250 ns. You could use an oscilloscope but you have an HP 16500A/510B on your bench. Since the timing analyzer will do just fine when you don’t need voltage parametrics, you decide to go ahead and use the logic analyzer.
