Chapter 1: Getting Started
Probing and Sampling Mode Selection Steps
If you chose Timing Mode
1. Select the timing analyzer conventional/transitional configuration.
In the transitional timing configuration, the logic analyzer can capture a
greater period of execution because only transitions are stored in memory.
2. If you chose the transitional timing configuration, set the sample period.
To capture signal level changes reliably, the sample period should be less
than half (many engineers prefer one-fourth) of the period of the fastest
signal you want to measure.
If you chose State Mode
1. Select the state analyzer speed configuration.
There are trade-offs between high-speed sampling, the number of available
channels, triggering capabilities, and other logic analyzer characteristics.
For example, in the 1250 Mb/s configuration, a periodic clock input signal
is required.
2. In the Clock Setup, specify which clock signal edges from the device under
test will be used as the sampling clock.
