The Analyzer Configuration Menu
Type field
The Type field lets you configure the logic 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 discrete activity. For more details on SPA, see Chapter 9.
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.
