The Analyzer Configuration Menu

Type field

The Type field allows you to configure the analyzer with either an internal
clock (Timing mode) or an external clock (State and SPA). When the Type
field is selected, the following choices are available.
Timing When Timing is selected, the analyzer uses its own internal
clock to clock measurement data into the acquisition memory. This clock
is asynchronous to the signals in the target system. Fields relating to
external clocks such as the Analyzer Format menu's Master Clock do not
appear and certain menus such as Compare are not available.
The analyzer can only be configured with one timing analyzer. If two are
selected, the first will be turned off.
State When State is selected, the analyzer uses a clock from the system
under test to clock measurement data into acquisition memory. This
clock is synchronous to the signals in the target system.
SPA SPA stands for System Performance Analysis. It uses an external
clock like a state analyzer but measures overall system performance
rather than recording an activity trace. For more details on SPA, see
Chapter 8.

Illegal configuration

When both analyzers are turned on, the first pod pair 1,2 and the last pod
pair (5,6 in the 96-channel model or 7,8 in the 128-channel model) cannot be
assigned to the same analyzer machine. If this configuration is set, the
analyzer will display a re-assignment menu when you try to leave the
configuration screen. Use this re-assignment menu to configure the pod
assignment automatically to a legal configuration.
