A logic analyzer records digital electrical signals.
Recording (sampling) is either...
Synchronous with some other signal, typically a clock or strobe
Asynchronous sampling a regular intervals controlled by an internal time base
The most outstanding diagnostic features of a logic analyzer
Pre-trigger view of signals leading to a TriggerEvent?
Channel Width large enough to view many signals, including busses
Logic analyzers are improved when they are made
LongerWiderFaster?, all attributes of their memory.
Equally important are sound MechanicalProbe? design
and SamplingElectronics?. Fancy information processing seems to
just get in the way. With complicated controls one is often
