Chapter 2: Probing and Selecting the Sampling Mode

Choosing the Sampling Mode

 

• 800 Mb/s / 64M State

 

In this configuration: The input clock signal can be periodic or

 

aperiodic, and either rising, falling, or both edges can indicate valid

 

data. The logic analyzer setup/hold window is 1 ns, and sampling

 

positions may be adjusted automatically or manually. The limited set of

 

16760 State trigger functions are available.

 

• 400 Mb/s / 32M State

 

In this configuration: Either rising, falling, or both edges can indicate

 

valid data. The logic analyzer setup/hold window is 2.5 ns, and sampling

 

positions may be adjusted automatically or manually. The limited set of

 

Turbo State trigger functions are available.

 

• 200 Mb/s / 32M State

 

In this configuration: Rising, falling, or both edges can indicate valid

 

data. The logic analyzer setup/hold window is 3.0 ns, and sampling

 

positions may be adjusted automatically or manually. The General

 

State trigger functions are available.

 

In all configurations but the 200 Mb/s / 32M State configuration, if time is

 

counted (that is time tags are being stored), one pod must be left

 

unassigned in order to store the time tags. In the 200 Mb/s / 32M State

 

configuration, memory depth is reduced by half if all pods are used and

 

time or state counts are being stored.

To set up the sampling clock

For the clock input signal that will be used:

1. In the Clock Setup, select the desired Mode. Your choices are Periodic or Aperiodic. If the State Mode is set to 1250 or 1500 Mb/s configuration, the input clock must be Periodic.

2. Select the pod's Master button (under the activity indicator).
