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 are ...
- 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 left DebuggingTheDebugger.
A StripChartRecorder may be slow and narrow, but it sure is long.
