Hi all,
I used to have an old Radio Shack logic probe that I really liked for its
audio output as I didn't have to take my eyes off of whatever I was probing
at the time to know if the corresponding signal was 'wiggling.' It also had
a 'level' mode -- where a high or low signal produced a high or low tone
(and indeterminate levels were mute) and a 'pulse' mode where each edge of a
signal would produce a quick 'beep.'
Unfortunately, it was designed for 5-15V and attempting to use it at 3.3V
didn't really work that well. Does anyone know of a comparable device that
does work at the now ubiquitous lower logic voltage rails? Down to 2.5V
woud be great -- even 1.8V is nice.
The Radio Shack probe's 'pulse' mode also had a minimum detectable pulse
width of 1us, I believe -- pretty glacial by today's standards. Something
<10ns would be good here too.
Thanks,
