Hi,
I have been looking for a way to record traces of 1W waveform. It is no different than a ttl-level rs232 with bit time of about 100uS which is no different than 9600 baud serial communication. The problem is that I don’t have digital scope and really, for something that slow I should be able to use a parallel port logic analyzer
The problem is that the logic analyzers that I have looked at all want to have their inputs clocked by an external clock source. That is understandable for the most common use of logic analyzer but in my case I want to use a logic analyzer much like one would use a digital oscilloscope. I want the analyzer to sample the input at specific time interval which is generated internally. So in my case, I expect a bit time of 100uS so the logic analyzer would need to read its input at a 50uS (the classic DSP sampling formula of f/2) rate which is about 20kHz
Can this be accomplished at all with a simple parallel port logic analyzer?
