The Analyzer Configuration Menu

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.

State Compare (1670E-series only). When State Compare is

selected, the Compare menu is available in the main menu selection.

For more details on Compare, see "The Compare Menu." State

Compare mode functions much like State mode, except that total

memory is reduced.

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
