Logic Analysis made easy: a self-paced training guide This training kit will quickly teach you how to use the HP 1660 and HP 1670 Series Logic Analyzers to get your work done. The exercises in this book will teach you how to perform basic timing and state analysis measurements and how to make more complex measurements, such as comparing two state listings, setting up complex state triggers, and making state and timing measurements simultaneously. You will also learn oscilloscope measurements

Introduction Using a Mouse You can perform all of the exercises in this training kit using a mouse. When an instruction tells you to highlight an item and press the Select key, you can simply point to that item with the mouse pointer and press the left mouse button. When you want to scroll up or down a list, you can press and hold down the right mouse button and move the mouse forward and backward. Remember, to scroll a field, the field must be highlighted and have the knob icon at the top of t

2 Introduction to Timing Analysis
ملخص المحتوى في الصفحة رقم 20
Introduction to Timing Analysis Timing analysis in its simplest form means acquiring and storing data at equal time intervals. When doing timing analysis you must put the logic analyzer into timing mode. An analyzer in timing mode is referred to as a timing analyzer. The timing analyzer’s time interval is controlled by a clock inside the analyzer, just like the clock in a digitizing oscilloscope. However, there are key differences between a timing analyzer and a digitizing oscilloscope. The
