Mixed Mode - Correlation of State and
Timing Data
Mixed mode allows you to analyze a system in both state and timing
modes simultaneously. A common example is using the state analyzer
to capture a problem that occurs infrequently and then using the
timing analyzer to analyze the problem in detail. The Mixed Mode
exercises will show you how to use the mixed mode capabilities of the
timing and state analyzers. These exercises are built on the timing
and state exercises in chapters 2 and 3.
If your logic analyzer is an HP 1663 or HP 1664, you will not be able to
perform these exercises. These analyzers have 32 data acquisition
channels on two pods. All 32 channels may be assigned to either state
or timing analysis, but they cannot be separated to perform mixed
mode measurements.
In this chapter you will:
• Connect the timing analyzer
• Enable time-correlation between the timing and state analyzers
• Arm the timing analyzer with the state analyzer
• Run the analyzers and view the mixed mode display with time
