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
